## NAME
podman-systemd.unit - systemd units using Podman Quadlet

## SYNOPSIS
name.container, name.volume, name.network, name.kube name.image, name.build name.pod, name.artifact

### Podman rootful unit search path
Quadlet files for the root user can be placed in the following directories ordered in precedence. Meaning duplicate named quadlets found under /run take precedence over ones in /etc, as well as those in /usr:

Temporary quadlets, usually used for testing:

•

/run/containers/systemd/

System administrator's defined quadlets:

•

/etc/containers/systemd/

Distribution defined quadlets:

•

/usr/share/containers/systemd/

### Podman rootless unit search path
Quadlet files for non-root users can be placed in the following directories:

- $XDG_RUNTIME_DIR/containers/systemd/

- $XDG_CONFIG_HOME/containers/systemd/ or ~/.config/containers/systemd/

- /etc/containers/systemd/users/$(UID)

- /etc/containers/systemd/users/

### Using symbolic links
Quadlet supports using symbolic links for the base of the search paths and inside them.

## DESCRIPTION
Podman supports building and starting containers (and creating volumes) via systemd by using a systemd generator. These files are read during boot (and when systemctl daemon-reload is run) and generate corresponding regular systemd service unit files. Both system and user systemd units are supported. All options and tables available in standard systemd unit files are supported. For example, options defined in the [Service] table and [Install] tables pass directly to systemd and are handled by it. See systemd.unit(5) man page for more information.

The Podman generator reads the search paths above and reads files with the extensions .container .volume, .network, .build, .pod, .kube, and .artifact, and for each file generates a similarly named .service file. Be aware that existing vendor services (i.e., in /usr/) are replaced if they have the same name. The generated unit files can be started and managed with systemctl like any other systemd service. systemctl {--user} list-unit-files lists existing unit files on the system.

The Podman files use the same format as regular systemd unit files. Each file type has a custom section (for example, [Container]) that is handled by Podman, and all other sections are passed on untouched, allowing the use of any normal systemd configuration options like dependencies or cgroup limits.

The source files also support drop-ins in the same way systemd does. For a given source file (foo.container), the corresponding .d directory (foo.container.d) will be scanned for files with a .conf extension, which are then merged into the base file in alphabetical order. Top-level type drop-ins (container.d) will also be included. If the unit contains dashes ("-") in the name (foo-bar-baz.container), then the drop-in directories generated by truncating the name after the dash are searched as well (foo-.container.d and foo-bar-.container.d). Drop-in files with the same name further down the hierarchy override those further up (foo-bar-baz.container.d/10-override.conf overrides foo-bar-.container.d/10-override.conf, which overrides foo-.service.d/10-override.conf, which overrides container.d/10-override.conf). The format of these drop-in files is the same as the base file. This is useful to alter or add configuration settings for a unit, without having to modify unit files.

For rootless containers, when administrators place Quadlet files in the /etc/containers/systemd/users directory, all users' sessions execute the Quadlet when the login session begins. If the administrator places a Quadlet file in the /etc/containers/systemd/users/${UID}/ directory, then only the user with the matching UID executes the Quadlet when the login session gets started. For unit files placed in subdirectories within /etc/containers/systemd/user/${UID}/ and the other user unit search paths, Quadlet will recursively search and run the unit files present in these subdirectories.

Note that Quadlet units do not support running as a non-root user by defining the User, Group, or DynamicUser systemd options. If you want to run a rootless Quadlet, you will need to create the user and add the unit file to one of the above rootless unit search paths.

Note: When a Quadlet is starting, Podman often pulls or builds one more container images which may take a considerable amount of time. Systemd defaults service start time to 90 seconds, or fails the service. Pre-pulling the image or extending the systemd timeout time for the service using the TimeoutStartSec Service option can fix the problem. A word of caution: TimeoutStartSec is not available for Type=oneshot units. Refer to systemd.service(5) for more information on how to handle long startup times for units which do not need to stay active once their main process has finished.

Adding the following snippet to a Quadlet file extends the systemd timeout to 15 minutes.

```
[Service]
TimeoutStartSec=900
```

Quadlet requires the use of cgroup v2, use podman info --format {{.Host.CgroupsVersion}} to check on the system.

### Service Type
By default, the Type field of the Service section of the Quadlet file does not need to be set. Quadlet will set it to notify for .container and .kube files, forking for .pod files, and oneshot for .volume, .network, .build, .image, and .artifact files.

However, Type may be explicitly set to oneshot for .container and .kube files when no containers are expected to run once podman exits.

When setting Type=oneshot, it is recommended to also set RemainAfterExit=yes to prevent the service state from becoming inactive (dead). However, when activating a service via a timer unit, having RemainAfterExit=yes leaves the job in a "started" state which prevents subsequent activations by the timer. For more information, see the systemd.service(5) man page.

Examples for such cases: - .container file with an image that exits after their entrypoint has finished

•

.kube file pointing to a Kubernetes Yaml file that does not define any containers. E.g. PVCs only

### Enabling unit files
The services created by Podman are considered transient by systemd, which means they don't have the same persistence rules as regular units. In particular, it is not possible to systemctl enable them in order for them to become automatically enabled on the next boot.

To compensate for this, the generator manually applies the [Install] section of the container definition unit files during generation, in the same way systemctl enable does when run later.

For example, to start a container on boot, add something like this to the file:

```
[Install]
WantedBy=default.target
```

Currently, only the Alias, WantedBy, RequiredBy, and UpheldBy keys are supported.

The Install section can be part of the main file, or it can be in a separate drop-in file as described above. The latter allows you to install an non-enabled unit and then later enabling it by installing the drop-in.

### Template files
Systemd supports a concept of template files. They are units with names of the form "basename@instancename.service" when they are running, but that can be instantiated multiple times from a single "basename@.service" file. The individual instances can also be different by using drop-in files with the full instance name.

Quadlets support these in two ways. First of all, a quadlet unit with a template form will generate a systemd service with a template form, and the template systemd service can be used as a regular template. For example, "foo@.container" will generate "foo@.service" and you can then "systemctl start foo@bar.service".

Secondly, if you make a symlink like "foo@instance.container", that will generate an instantiated template file. When generating this file quadlet will read drop-in files both from the instanced directory (foo@instance.container.d) and the template directory (foo@.container.d). This allows customization of individual instances.

Instanced template files (like foo@bar.container) can be enabled just like non-templated ones. However, templated ones (foo@.container) are different, because they need to be instantiated. If the [Install] section contains a DefaultInstance= key, then that instance will be enabled, but if not, nothing will happen and the options will only be used as the default for units that are instantiated using symlinks.

An example template file sleep@.container might look like this:

```
[Unit]
Description=A templated sleepy container
[Container]
Image=quay.io/fedora/fedora
Exec=sleep %i
[Service]
# Restart service when sleep finishes
Restart=always
[Install]
WantedBy=multi-user.target
DefaultInstance=100
```

If this is installed, then on boot there will be a sleep@100.service running that sleeps for 100 seconds. You can then do something like systemctl start sleep@50.service to start another instance that sleeps 50 seconds, or alternatively another service can start it via a dependency like Wants=sleep@50.service.

In addition, if you do ln -s sleep@.container sleep@10.container you will also have a 10 second sleep running at boot. And, if you want that particular instance to be running with another image, you can create a drop-in file like sleep@10.container.d/10-image.conf:

```
[Container]
Image=quay.io/centos/centos
```

### Relative paths
In order to support Systemd specifiers, Quadlet does not resolve relative paths that start with %. To resolve such a path, prepend it with ./.

For example, instead of EnvironmentFile=%n/env use EnvironmentFile=./%n/env

### Debugging unit files
After placing the unit file in one of the unit search paths (mentioned above), you can start it with systemctl start {--user}. If it fails with "Failed to start example.service: Unit example.service not found.", then it is possible that you used incorrect syntax or you used an option from a newer version of Podman Quadlet and the generator failed to create a service file.

View the generated files and/or error messages with:

```
/usr/lib/systemd/system-generators/podman-system-generator {--user} --dryrun
```

Alternatively, show only the errors with:

```
systemd-analyze {--user} --generators=true verify example.service
```

That command also performs additional checks on the generated service unit. For details, see systemd-analyze(1) man page.

### Debugging a limited set of unit files
If you would like to debug a limited set of unit files, you can copy them to a separate directory and set the QUADLET_UNIT_DIRS environment variable to this directory when running the command below:

```
QUADLET_UNIT_DIRS=<Directory> /usr/lib/systemd/system-generators/podman-system-generator {--user} --dryrun
```

This will instruct Quadlet to look for units in this directory instead of the common ones and by that limit the output to only the units you are debugging.

### Implicit network dependencies
Quadlet will add dependencies on network-online.target (as root) or podman-user-wait-network-online.service (as user) by adding After= and Wants= properties to the unit. This is to ensure that the network is reachable if an image needs to be pulled and by the time the container is started.

The special case podman-user-wait-network-online.service unit is needed as user because user units are unable to wait for system (root) units so network-online.target doesn't do anything there and is instead ignored. As this caused a significant amount of issues we decided to work around this with our own special purpose unit that simply checks if the network-online.target unit is active with systemctl is-active network-online.target.

This behavior can be disabled by adding DefaultDependencies=false in the Quadlet section. Note, the systemd [Unit] section has an option with the same name but a different meaning.

### Dependency between Quadlet units
Quadlet will automatically translate dependencies, specified in the keys Wants, Requires, Requisite, BindsTo, PartOf, Upholds, Conflicts, Before and After of the [Unit] section, between different Quadlet units.

For example the fedora.container unit below specifies a dependency on the basic.container unit.

```
[Unit]
After=basic.container
Requires=basic.container
[Container]
Image=registry.fedoraproject.org/fedora:41
```

### Setting resource names
Quadlet units allow setting the names of the created resources (e.g. VolumeName for .volume units or PodName for .pod units).

Note that using systemd specifiers that reference the generated service unit (e.g. $N) breaks Quadlet's ability to link between resources as they are translated differently in each service

## Container units [Container]
Container units are named with a .container extension and contain a [Container] section describing the container that is run as a service. The resulting service file contains a line like ExecStart=podman run … image-name, and most of the keys in this section control the command-line options passed to Podman. However, some options also affect the details of how systemd is set up to run and interact with the container.

By default, the Podman container has the same name as the unit, but with a systemd- prefix, i.e. a $name.container file creates a $name.service unit and a systemd-$name Podman container. The ContainerName option allows for overriding this default name with a user-provided one.

There is only one required key, Image, which defines the container image the service runs.

Valid options for [Container] are listed below:

Description of [Container] section are:

### AddCapability=
Add these capabilities, in addition to the default Podman capability set, to the container.

This is a space separated list of capabilities. This key can be listed multiple times.

For example:

```
AddCapability=CAP_DAC_OVERRIDE CAP_IPC_OWNER
```

### AddDevice=
Adds a device node from the host into the container. The format of this is HOST-DEVICE[:CONTAINER-DEVICE][:PERMISSIONS], where HOST-DEVICE is the path of the device node on the host, CONTAINER-DEVICE is the path of the device node in the container, and PERMISSIONS is a list of permissions combining 'r' for read, 'w' for write, and 'm' for mknod(2). The - prefix tells Quadlet to add the device only if it exists on the host.

This key can be listed multiple times.

### AddHost=
Add host-to-IP mapping to /etc/hosts. The format is hostname:ip.

Equivalent to the Podman --add-host option. This key can be listed multiple times.

### Annotation=
Set one or more OCI annotations on the container. The format is a list of key=value items, similar to Environment.

This key can be listed multiple times.

### AutoUpdate=
Indicates whether the container will be auto-updated (podman-auto-update(1)). The following values are supported:

- registry: Requires a fully-qualified image reference (e.g., quay.io/podman/stable:latest) to be used to create the container. This enforcement is necessary to know which image to actually check and pull. If an image ID was used, Podman does not know which image to check/pull anymore.

- local: Tells Podman to compare the image a container is using to the image with its raw name in local storage. If an image is updated locally, Podman simply restarts the systemd unit executing the container.

### CgroupsMode=
The cgroups mode of the Podman container. Equivalent to the Podman --cgroups option.

By default, the cgroups mode of the container created by Quadlet is split, which differs from the default (enabled) used by the Podman CLI.

If the container joins a pod (i.e. Pod= is specified), you may want to change this to no-conmon or enabled so that pod level cgroup resource limits can take effect.

### ContainerName=
The (optional) name of the Podman container. If this is not specified, the default value of systemd-%N is used, which is the same as the service name but with a systemd- prefix to avoid conflicts with user-managed containers.

### ContainersConfModule=
Load the specified containers.conf(5) module. Equivalent to the Podman --module option.

This key can be listed multiple times.

### DNS=
Set network-scoped DNS resolver/nameserver for containers in this network.

This key can be listed multiple times.

### DNSOption=
Set custom DNS options.

This key can be listed multiple times.

### DNSSearch=
Set custom DNS search domains. Use DNSSearch=. to remove the search domain.

This key can be listed multiple times.

### DropCapability=
Drop these capabilities from the default podman capability set, or all to drop all capabilities.

This is a space separated list of capabilities. This key can be listed multiple times.

For example:

```
DropCapability=CAP_DAC_OVERRIDE CAP_IPC_OWNER
```

### Entrypoint=
Override the default ENTRYPOINT from the image. Equivalent to the Podman --entrypoint option. Specify multi option commands in the form of a JSON string.

### Environment=
Set an environment variable in the container. This uses the same format as services in systemd and can be listed multiple times.

### EnvironmentFile=
Use a line-delimited file to set environment variables in the container. The path may be absolute or relative to the location of the unit file. This key may be used multiple times, and the order persists when passed to podman run.

### EnvironmentHost=
Use the host environment inside of the container.

### Exec=
Additional arguments for the container; this has exactly the same effect as passing more arguments after a podman run <image> <arguments> invocation.

The format is the same as for systemd command lines, However, unlike the usage scenario for similarly-named systemd ExecStart= verb which operates on the ambient root filesystem, it is very common for container images to have their own ENTRYPOINT or CMD metadata which this interacts with.

The default expectation for many images is that the image will include an ENTRYPOINT with a default binary, and this field will add arguments to that entrypoint.

Another way to describe this is that it works the same way as the args field in a Kubernetes pod.

### ExposeHostPort=
Exposes a port, or a range of ports (e.g. 50-59), from the host to the container. Equivalent to the Podman --expose option.

This key can be listed multiple times.

### GIDMap=
Run the container in a new user namespace using the supplied GID mapping. Equivalent to the Podman --gidmap option.

This key can be listed multiple times.

### GlobalArgs=
This key contains a list of arguments passed directly between podman and run in the generated file. It can be used to access Podman features otherwise unsupported by the generator. Since the generator is unaware of what unexpected interactions can be caused by these arguments, it is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### Group=
The (numeric) GID to run as inside the container. This does not need to match the GID on the host, which can be modified with UserNS, but if that is not specified, this GID is also used on the host.

Note: when both User= and Group= are specified, they are combined into a single --user USER:GROUP argument passed to Podman. Using Group= without User= will result in an error.

### GroupAdd=
Assign additional groups to the primary user running within the container process. Also supports the keep-groups special flag. Equivalent to the Podman --group-add option.

### HealthCmd=
Set or alter a healthcheck command for a container. A value of none disables existing healthchecks. Equivalent to the Podman --health-cmd option.

### HealthInterval=
Set an interval for the healthchecks. An interval of disable results in no automatic timer setup. Equivalent to the Podman --health-interval option.

### HealthLogDestination=
Set the destination of the HealthCheck log. Directory path, local or events_logger (local use container state file) (Default: local) Equivalent to the Podman --health-log-destination option.

- local: (default) HealthCheck logs are stored in overlay containers. (For example: $runroot/healthcheck.log)

- directory: creates a log file named <container-ID>-healthcheck.log with HealthCheck logs in the specified directory.

- events_logger: The log will be written with logging mechanism set by events_logger. It also saves the log to a default directory, for performance on a system with a large number of logs.

### HealthMaxLogCount=
Set maximum number of attempts in the HealthCheck log file. ('0' value means an infinite number of attempts in the log file) (Default: 5 attempts) Equivalent to the Podman --Health-max-log-count option.

### HealthMaxLogSize=
Set maximum length in characters of stored HealthCheck log. ("0" value means an infinite log length) (Default: 500 characters) Equivalent to the Podman --Health-max-log-size option.

### HealthOnFailure=
Action to take once the container transitions to an unhealthy state. The "kill" action in combination integrates best with systemd. Once the container turns unhealthy, it gets killed, and systemd restarts the service. Equivalent to the Podman --health-on-failure option.

### HealthRetries=
The number of retries allowed before a healthcheck is considered to be unhealthy. Equivalent to the Podman --health-retries option.

### HealthStartPeriod=
The initialization time needed for a container to bootstrap. Equivalent to the Podman --health-start-period option.

### HealthStartupCmd=
Set a startup healthcheck command for a container. Equivalent to the Podman --health-startup-cmd option.

### HealthStartupInterval=
Set an interval for the startup healthcheck. An interval of disable results in no automatic timer setup. Equivalent to the Podman --health-startup-interval option.

### HealthStartupRetries=
The number of attempts allowed before the startup healthcheck restarts the container. Equivalent to the Podman --health-startup-retries option.

### HealthStartupSuccess=
The number of successful runs required before the startup healthcheck succeeds and the regular healthcheck begins. Equivalent to the Podman --health-startup-success option.

### HealthStartupTimeout=
The maximum time a startup healthcheck command has to complete before it is marked as failed. Equivalent to the Podman --health-startup-timeout option.

### HealthTimeout=
The maximum time allowed to complete the healthcheck before an interval is considered failed. Equivalent to the Podman --health-timeout option.

### HostName=
Sets the host name that is available inside the container. Equivalent to the Podman --hostname option.

### HttpProxy=
Controls whether proxy environment variables (http_proxy, https_proxy, ftp_proxy, no_proxy) are passed from the Podman process into the container during image pulls and builds.

Set to true to enable proxy inheritance (default Podman behavior) or false to disable it. This option is particularly useful on systems that require proxy configuration for internet access but don't want proxy settings passed to the container runtime.

Equivalent to the Podman --http-proxy option.

### Image=
The image to run in the container. It is recommended to use a fully qualified image name rather than a short name, both for performance and robustness reasons.

The format of the name is the same as when passed to podman pull. So, it supports using :tag or digests to guarantee the specific image version.

Special Cases:

- If the name of the image ends with .image, Quadlet will use the image pulled by the corresponding .image file, and the generated systemd service contains a dependency on the $name-image.service (or the service name set in the .image file). Note that the corresponding .image file must exist.

- If the name of the image ends with .build, Quadlet will use the image built by the corresponding .build file, and the generated systemd service contains a dependency on the $name-build.service. Note: the corresponding .build file must exist.

### IP=
Specify a static IPv4 address for the container, for example 10.88.64.128. Equivalent to the Podman --ip option.

### IP6=
Specify a static IPv6 address for the container, for example fd46:db93:aa76:ac37::10. Equivalent to the Podman --ip6 option.

### Label=
Set one or more OCI labels on the container. The format is a list of key=value items, similar to Environment.

This key can be listed multiple times.

### LogDriver=
Set the log-driver used by Podman when running the container. Equivalent to the Podman --log-driver option.

### LogOpt=
Set the log-opt (logging options) used by Podman when running the container. Equivalent to the Podman --log-opt option. This key can be listed multiple times.

### Mask=
Specify the paths to mask separated by a colon. Mask=/path/1:/path/2. A masked path cannot be accessed inside the container.

### Memory=
Specify the amount of memory for the container.

### Mount=
Attach a filesystem mount to the container. This is equivalent to the Podman --mount option, and generally has the form type=TYPE,TYPE-SPECIFIC-OPTION[,...].

Special cases:

- For type=volume, if source ends with .volume, the Podman named volume generated by the corresponding .volume file is used.

- For type=image, if source ends with .image, the image generated by the corresponding .image file is used.

In both cases, the generated systemd service will contain a dependency on the service generated for the corresponding unit. Note: the corresponding .volume or .image file must exist.

This key can be listed multiple times.

### Network=
Specify a custom network for the container. This has the same format as the --network option to podman run. For example, use host to use the host network in the container, or none to not set up networking in the container.

Special cases:

- If the name of the network ends with .network, a Podman network called systemd-$name is used, and the generated systemd service contains a dependency on the $name-network.service. Such a network can be automatically created by using a $name.network Quadlet file. Note: the corresponding .network file must exist.

- If the name ends with .container, the container will reuse the network stack of another container created by $name.container. The generated systemd service contains a dependency on $name.service. Note: the corresponding .container file must exist.

This key can be listed multiple times.

### NetworkAlias=
Add a network-scoped alias for the container. This has the same format as the --network-alias option to podman run. Aliases can be used to group containers together in DNS resolution: for example, setting NetworkAlias=web on multiple containers will make a DNS query for web resolve to all the containers with that alias.

This key can be listed multiple times.

### NoNewPrivileges= (defaults to false)
If enabled, this disables the container processes from gaining additional privileges via things like setuid and file capabilities.

### Notify= (defaults to false)
By default, Podman is run in such a way that the systemd startup notify command is handled by the container runtime. In other words, the service is deemed started when the container runtime starts the child in the container. However, if the container application supports sd_notify, then setting Notify to true passes the notification details to the container allowing it to notify of startup on its own.

In addition, setting Notify to healthy will postpone startup notifications until such time as the container is marked healthy, as determined by Podman healthchecks. Note that this requires setting up a container healthcheck, see the HealthCmd option for more.

### PidsLimit=
Tune the container's pids limit. This is equivalent to the Podman --pids-limit option.

### Pod=
Specify a Quadlet .pod unit to link the container to. The value must take the form of <name>.pod and the .pod unit must exist.

Quadlet will add all the necessary parameters to link between the container and the pod and between their corresponding services.

### PodmanArgs=
This key contains a list of arguments passed directly to the end of the podman run command in the generated file (right before the image name in the command line). It can be used to access Podman features otherwise unsupported by the generator. Since the generator is unaware of what unexpected interactions can be caused by these arguments, it is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### PublishPort=
Exposes a port, or a range of ports (e.g. 50-59), from the container to the host. Equivalent to the Podman --publish option. The format is similar to the Podman options, which is of the form ip:hostPort:containerPort, ip::containerPort, hostPort:containerPort or containerPort, where the number of host and container ports must be the same (in the case of a range).

If the IP is set to 0.0.0.0 or not set at all, the port is bound on all IPv4 addresses on the host; use [::] for IPv6.

Note that not listing a host port means that Podman automatically selects one, and it may be different for each invocation of service. This makes that a less useful option. The allocated port can be found with the podman port command.

This key can be listed multiple times.

### Pull=
Set the image pull policy. This is equivalent to the Podman --pull option

### ReadOnly= (defaults to false)
If enabled, makes the image read-only.

### ReadOnlyTmpfs= (defaults to true)
If ReadOnly is set to true, mount a read-write tmpfs on /dev, /dev/shm, /run, /tmp, and /var/tmp.

### ReloadCmd=
Add ExecReload line to the Service that runs podman exec with this command in this container.

In order to execute the reload run systemctl reload <Service>

Mutually exclusive with ReloadSignal

### ReloadSignal=
Add ExecReload line to the Service that runs podman kill with this signal which sends the signal to the main container process.

In order to execute the reload run systemctl reload <Service>

Mutually exclusive with ReloadCmd

### Retry=
Number of times to retry the image pull when a HTTP error occurs. Equivalent to the Podman --retry option.

### RetryDelay=
Delay between retries. Equivalent to the Podman --retry-delay option.

### Rootfs=
The rootfs to use for the container. Rootfs points to a directory on the system that contains the content to be run within the container. This option conflicts with the Image option.

The format of the rootfs is the same as when passed to podman run --rootfs, so it supports overlay mounts as well.

Note: On SELinux systems, the rootfs needs the correct label, which is by default unconfined_u:object_r:container_file_t:s0.

### RunInit= (defaults to false)
If enabled, the container has a minimal init process inside the container that forwards signals and reaps processes.

### SeccompProfile=
Set the seccomp profile to use in the container. If unset, the default podman profile is used. Set to either the pathname of a JSON file, or unconfined to disable the seccomp filters.

### Secret=
Use a Podman secret in the container either as a file or an environment variable. This is equivalent to the Podman --secret option and generally has the form secret[,opt=opt ...]

### SecurityLabelDisable=
Turn off label separation for the container.

### SecurityLabelFileType=
Set the label file type for the container files.

### SecurityLabelLevel=
Set the label process level for the container processes.

### SecurityLabelNested=
Allow SecurityLabels to function within the container. This allows separation of containers created within the container.

### SecurityLabelType=
Set the label process type for the container processes.

### ShmSize=
Size of /dev/shm.

This is equivalent to the Podman --shm-size option and generally has the form number[unit]

### StartWithPod=
Start the container after the associated pod is created. Default to true.

If true, container will be started/stopped/restarted alongside the pod.

If false, the container will not be started when the pod starts. The container will be stopped with the pod. Restarting the pod will also restart the container as long as the container was also running before.

Note, the container can still be started manually or through a target by configuring the [Install] section. The pod will be started as needed in any case.

### StopSignal=
Signal to stop a container. Default is SIGTERM.

This is equivalent to the Podman --stop-signal option

### StopTimeout=
Seconds to wait before forcibly stopping the container.

Note, this value should be lower than the actual systemd unit timeout to make sure the podman rm command is not killed by systemd.

This is equivalent to the Podman --stop-timeout option

### SubGIDMap=
Run the container in a new user namespace using the map with name in the /etc/subgid file. Equivalent to the Podman --subgidname option.

### SubUIDMap=
Run the container in a new user namespace using the map with name in the /etc/subuid file. Equivalent to the Podman --subuidname option.

### Sysctl=
Configures namespaced kernel parameters for the container. The format is Sysctl=name=value.

This is a space separated list of kernel parameters. This key can be listed multiple times.

For example:

```
Sysctl=net.ipv6.conf.all.disable_ipv6=1 net.ipv6.conf.all.use_tempaddr=1
```

### Timezone= (if unset uses system-configured default)
The timezone to run the container in.

### Tmpfs=
Mount a tmpfs in the container. This is equivalent to the Podman --tmpfs option, and generally has the form CONTAINER-DIR[:OPTIONS].

This key can be listed multiple times.

### UIDMap=
Run the container in a new user namespace using the supplied UID mapping. Equivalent to the Podman --uidmap option.

This key can be listed multiple times.

### Ulimit=
Ulimit options. Sets the ulimits values inside of the container.

This key can be listed multiple times.

### Unmask=
Specify the paths to unmask separated by a colon. unmask=ALL or /path/1:/path/2, or shell expanded paths (/proc/*):

If set to ALL, Podman will unmask all the paths that are masked or made read-only by default.

The default masked paths are /proc/acpi, /proc/kcore, /proc/keys, /proc/latency_stats, /proc/sched_debug, /proc/scsi, /proc/timer_list, /proc/timer_stats, /sys/firmware, and /sys/fs/selinux.

The default paths that are read-only are /proc/asound, /proc/bus, /proc/fs, /proc/irq, /proc/sys, /proc/sysrq-trigger, /sys/fs/cgroup.

### User=
The (numeric) UID to run as inside the container. This does not need to match the UID on the host, which can be modified with UserNS, but if that is not specified, this UID is also used on the host.

Note: when both User= and Group= are specified, they are combined into a single --user USER:GROUP argument passed to Podman.

### UserNS=
Set the user namespace mode for the container. This is equivalent to the Podman --userns option and generally has the form MODE[:OPTIONS,...].

### Volume=
Mount a volume in the container. This is equivalent to the Podman --volume option, and generally has the form [[SOURCE-VOLUME|HOST-DIR:]CONTAINER-DIR[:OPTIONS]].

If SOURCE-VOLUME starts with ., Quadlet resolves the path relative to the location of the unit file.

Special case:

•

If SOURCE-VOLUME ends with .volume, a Podman named volume called systemd-$name is used as the source, and the generated systemd service contains a dependency on the $name-volume.service. Note that the corresponding .volume file must exist.

This key can be listed multiple times.

### WorkingDir=
Working directory inside the container.

The default working directory for running binaries within a container is the root directory (/). The image developer can set a different default with the WORKDIR instruction. This option overrides the working directory by using the -w option.

## Pod units [Pod]
Pod units are named with a .pod extension and contain a [Pod] section describing the pod that is created and run as a service. The resulting service file contains a line like ExecStartPre=podman pod create …, and most of the keys in this section control the command-line options passed to Podman.

By default, the Podman pod has the same name as the unit, but with a systemd- prefix, i.e. a $name.pod file creates a $name-pod.service unit and a systemd-$name Podman pod. The PodName option allows for overriding this default name with a user-provided one.

Valid options for [Pod] are listed below:

Supported keys in the [Pod] section are:

### AddHost=
Add host-to-IP mapping to /etc/hosts. The format is hostname:ip.

Equivalent to the Podman --add-host option. This key can be listed multiple times.

### ContainersConfModule=
Load the specified containers.conf(5) module. Equivalent to the Podman --module option.

This key can be listed multiple times.

### DNS=
Set network-scoped DNS resolver/nameserver for containers in this pod.

This key can be listed multiple times.

### DNSOption=
Set custom DNS options.

This key can be listed multiple times.

### DNSSearch=
Set custom DNS search domains. Use DNSSearch=. to remove the search domain.

This key can be listed multiple times.

### ExitPolicy=
Set the exit policy of the pod when the last container exits. Default for quadlets is stop.

To keep the pod active, set ExitPolicy=continue.

### GIDMap=
Create the pod in a new user namespace using the supplied GID mapping. Equivalent to the Podman --gidmap option.

This key can be listed multiple times.

### GlobalArgs=
This key contains a list of arguments passed directly between podman and pod in the generated file. It can be used to access Podman features otherwise unsupported by the generator. Since the generator is unaware of what unexpected interactions can be caused by these arguments, it is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### HostName=
Set the pod’s hostname inside all containers.

The given hostname is also added to the /etc/hosts file using the container’s primary IP address (also see the --add-host option).

Equivalent to the Podman --hostname option. This key can be listed multiple times.

### IP=
Specify a static IPv4 address for the pod, for example 10.88.64.128. Equivalent to the Podman --ip option.

### IP6=
Specify a static IPv6 address for the pod, for example fd46:db93:aa76:ac37::10. Equivalent to the Podman --ip6 option.

### Label=
Set one or more OCI labels on the pod. The format is a list of key=value items, similar to Environment.

This key can be listed multiple times.

### Network=
Specify a custom network for the pod. This has the same format as the --network option to podman pod create. For example, use host to use the host network in the pod, or none to not set up networking in the pod.

Special case:

•

If the name of the network ends with .network, Quadlet will look for the corresponding .network Quadlet unit. If found, Quadlet will use the name of the Network set in the Unit, otherwise, systemd-$name is used.

The generated systemd service contains a dependency on the service unit generated for that .network unit. Note: the corresponding .network file must exist.

This key can be listed multiple times.

### NetworkAlias=
Add a network-scoped alias for the pod. This has the same format as the --network-alias option to podman pod create. Aliases can be used to group containers together in DNS resolution: for example, setting NetworkAlias=web on multiple containers will make a DNS query for web resolve to all the containers with that alias.

This key can be listed multiple times.

### PodmanArgs=
This key contains a list of arguments passed directly to the end of the podman pod create command in the generated file. It can be used to access Podman features otherwise unsupported by the generator. Since the generator is unaware of what unexpected interactions can be caused by these arguments, is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### PodName=
The (optional) name of the Podman pod. If this is not specified, the default value is the same name as the unit, but with a systemd- prefix, i.e. a $name.pod file creates a systemd-$name Podman pod to avoid conflicts with user-managed pods.

Please note that pods and containers cannot have the same name. So, if PodName is set, it must not conflict with any container.

### PublishPort=
Exposes a port, or a range of ports (e.g. 50-59), from the pod to the host. Equivalent to the Podman --publish option. The format is similar to the Podman options, which is of the form ip:hostPort:containerPort, ip::containerPort, hostPort:containerPort or containerPort, where the number of host and container ports must be the same (in the case of a range).

If the IP is set to 0.0.0.0 or not set at all, the port is bound on all IPv4 addresses on the host; use [::] for IPv6.

Note that not listing a host port means that Podman automatically selects one, and it may be different for each invocation of service. This makes that a less useful option. The allocated port can be found with the podman port command.

When using host networking via Network=host, the PublishPort= option cannot be used.

This key can be listed multiple times.

### ServiceName=
By default, Quadlet will name the systemd service unit by appending -pod to the name of the Quadlet. Setting this key overrides this behavior by instructing Quadlet to use the provided name.

Note, the name should not include the .service file extension

### ShmSize=
Size of /dev/shm.

This is equivalent to the Podman --shm-size option and generally has the form number[unit]

### StopTimeout=
Sets the time in seconds to wait for the pod to gracefully stop. This value is equivalent to the --time argument in the podman pod stop command when the service is stopped. After this period expires, any running containers in the pod are forcibly killed.

### SubGIDMap=
Create the pod in a new user namespace using the map with name in the /etc/subgid file. Equivalent to the Podman --subgidname option.

### SubUIDMap=
Create the pod in a new user namespace using the map with name in the /etc/subuid file. Equivalent to the Podman --subuidname option.

### UIDMap=
Create the pod in a new user namespace using the supplied UID mapping. Equivalent to the Podman --uidmap option.

This key can be listed multiple times.

### UserNS=
Set the user namespace mode for the pod. This is equivalent to the Podman --userns option and generally has the form MODE[:OPTIONS,...].

### Volume=
Mount a volume in the pod. This is equivalent to the Podman --volume option, and generally has the form [[SOURCE-VOLUME|HOST-DIR:]CONTAINER-DIR[:OPTIONS]].

If SOURCE-VOLUME starts with ., Quadlet resolves the path relative to the location of the unit file.

Special case:

•

If SOURCE-VOLUME ends with .volume, Quadlet will look for the corresponding .volume Quadlet unit. If found, Quadlet will use the name of the Volume set in the Unit, otherwise, systemd-$name is used. Note: the corresponding .volume file must exist.

The generated systemd service contains a dependency on the service unit generated for that .volume unit, or on $name-volume.service if the .volume unit is not found.

This key can be listed multiple times.

## Kube units [Kube]
Kube units are named with a .kube extension and contain a [Kube] section describing how podman kube play runs as a service. The resulting service file contains a line like ExecStart=podman kube play … file.yml, and most of the keys in this section control the command-line options passed to Podman. However, some options also affect the details of how systemd is set up to run and interact with the container.

There is only one required key, Yaml, which defines the path to the Kubernetes YAML file.

Valid options for [Kube] are listed below:

[Kube] options

--userns keep-id:uid=200,gid=210

Yaml=/tmp/kube.yaml

podman kube play /tmp/kube.yaml

Supported keys in the [Kube] section are:

### AutoUpdate=
Indicates whether containers will be auto-updated (podman-auto-update(1)). AutoUpdate can be specified multiple times. The following values are supported:

- registry: Requires a fully-qualified image reference (e.g., quay.io/podman/stable:latest) to be used to create the container. This enforcement is necessary to know which images to actually check and pull. If an image ID was used, Podman does not know which image to check/pull anymore.

- local: Tells Podman to compare the image a container is using to the image with its raw name in local storage. If an image is updated locally, Podman simply restarts the systemd unit executing the Kubernetes Quadlet.

- name/(local|registry): Tells Podman to perform the local or registry autoupdate on the specified container name.

### ConfigMap=
Pass the Kubernetes ConfigMap YAML path to podman kube play via the --configmap argument. Unlike the configmap argument, the value may contain only one path but it may be absolute or relative to the location of the unit file.

This key may be used multiple times

### ContainersConfModule=
Load the specified containers.conf(5) module. Equivalent to the Podman --module option.

This key can be listed multiple times.

### ExitCodePropagation=
Control how the main PID of the systemd service should exit. The following values are supported: - all: exit non-zero if all containers have failed (i.e., exited non-zero) - any: exit non-zero if any container has failed - none: exit zero and ignore failed containers

The current default value is none.

### GlobalArgs=
This key contains a list of arguments passed directly between podman and kube in the generated file. It can be used to access Podman features otherwise unsupported by the generator. Since the generator is unaware of what unexpected interactions can be caused by these arguments, it is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### KubeDownForce=
Remove all resources, including volumes, when calling podman kube down. Equivalent to the Podman --force option.

### LogDriver=
Set the log-driver Podman uses when running the container. Equivalent to the Podman --log-driver option.

### Network=
Specify a custom network for the container. This has the same format as the --network option to podman kube play. For example, use host to use the host network in the container, or none to not set up networking in the container.

Special case:

•

If the name of the network ends with .network, a Podman network called systemd-$name is used, and the generated systemd service contains a dependency on the $name-network.service. Such a network can be automatically created by using a $name.network Quadlet file. Note: the corresponding .network file must exist.

This key can be listed multiple times.

### PodmanArgs=
This key contains a list of arguments passed directly to the end of the podman kube play command in the generated file (right before the path to the yaml file in the command line). It can be used to access Podman features otherwise unsupported by the generator. Since the generator is unaware of what unexpected interactions can be caused by these arguments, is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### PublishPort=
Exposes a port, or a range of ports (e.g. 50-59), from the container to the host. Equivalent to the podman kube play's --publish option. The format is similar to the Podman options, which is of the form ip:hostPort:containerPort, ip::containerPort, hostPort:containerPort or containerPort, where the number of host and container ports must be the same (in the case of a range).

If the IP is set to 0.0.0.0 or not set at all, the port is bound on all IPv4 addresses on the host; use [::] for IPv6.

The list of published ports specified in the unit file is merged with the list of ports specified in the Kubernetes YAML file. If the same container port and protocol is specified in both, the entry from the unit file takes precedence

This key can be listed multiple times.

### SetWorkingDirectory=
Set the WorkingDirectory field of the Service group of the Systemd service unit file. Used to allow podman kube play to correctly resolve relative paths. Supported values are yaml and unit to set the working directory to that of the YAML or Quadlet Unit file respectively.

Alternatively, users can explicitly set the WorkingDirectory field of the Service group in the .kube file. Please note that if the WorkingDirectory field of the Service group is set, Quadlet will not set it even if SetWorkingDirectory is set

Special case: * If multiple Yaml path are provided only unit is supported.

### UserNS=
Set the user namespace mode for the container. This is equivalent to the Podman --userns option and generally has the form MODE[:OPTIONS,...].

### Yaml=
The path, absolute or relative to the location of the unit file, to the Kubernetes YAML file to use.

This key can be listed multiple times.

## Network units [Network]
Network files are named with a .network extension and contain a section [Network] describing the named Podman network. The generated service is a one-time command that ensures that the network exists on the host, creating it if needed.

By default, the Podman network has the same name as the unit, but with a systemd- prefix, i.e. for a network file named $NAME.network, the generated Podman network is called systemd-$NAME, and the generated service file is $NAME-network.service. The NetworkName option allows for overriding this default name with a user-provided one.

Please note that stopping the corresponding service will not remove the podman network. In addition, updating an existing network is not supported. In order to update the network parameters you will first need to manually remove the podman network and then restart the service.

Using network units allows containers to depend on networks being automatically pre-created. This is particularly interesting when using special options to control network creation, as Podman otherwise creates networks with the default options.

Valid options for [Network] are listed below:

This key can be listed multiple times.

### GlobalArgs=
This key contains a list of arguments passed directly between podman and network in the generated file. It can be used to access Podman features otherwise unsupported by the generator. Since the generator is unaware of what unexpected interactions can be caused by these arguments, it is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### InterfaceName=
This option maps the network_interface option in the network config, see podman network inspect. Depending on the driver, this can have different effects; for bridge, it uses the bridge interface name. For macvlan and ipvlan, it is the parent device on the host. It is the same as --opt parent=....

This is equivalent to the Podman --interface-name option.

### Internal= (defaults to false)
Restrict external access of this network.

This is equivalent to the Podman --internal option

### IPAMDriver=
Set the ipam driver (IP Address Management Driver) for the network. Currently host-local, dhcp and none are supported.

This is equivalent to the Podman --ipam-driver option

### IPRange=

### NetworkDeleteOnStop= (defaults to false)
When set to true the network is deleted when the service is stopped

### NetworkName=
The (optional) name of the Podman network. If this is not specified, the default value is the same name as the unit, but with a systemd- prefix, i.e. a $name.network file creates a systemd-$name Podman network to avoid conflicts with user-managed network.

### Options=
Set driver specific options.

This is equivalent to the Podman --opt option

### PodmanArgs=
This key contains a list of arguments passed directly to the end of the podman network create command in the generated file (right before the name of the network in the command line). It can be used to access Podman features otherwise unsupported by the generator. Since the generator is unaware of what unexpected interactions can be caused by these arguments, is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### Subnet=
The subnet in CIDR notation.

This is equivalent to the Podman --subnet option

Volume files are named with a .volume extension and contain a section [Volume] describing the named Podman volume. The generated service is a one-time command that ensures that the volume exists on the host, creating it if needed.

By default, the Podman volume has the same name as the unit, but with a systemd- prefix, i.e. for a volume file named $NAME.volume, the generated Podman volume is called systemd-$NAME, and the generated service file is $NAME-volume.service. The VolumeName option allows for overriding this default name with a user-provided one.

Using volume units allows containers to depend on volumes being automatically pre-created. This is particularly interesting when using special options to control volume creation, as Podman otherwise creates volumes with the default options.

Valid options for [Volume] are listed below:

[Volume] options

podman volume create equivalent

ContainersConfModule=/etc/nvd.conf

--module=/etc/nvd.conf

Copy=true

--opt copy

Device=tmpfs

--opt device=tmpfs

Driver=image

--driver=image

GlobalArgs=--log-level=debug

--log-level=debug

Group=192

--opt group=192

Image=quay.io/centos/centos:latest

--opt image=quay.io/centos/centos:latest

Label="foo=bar"

--label "foo=bar"

Options=XYZ

--opt "o=XYZ"

PodmanArgs=--driver=image

--driver=image

Type=type

Filesystem type of Device

User=123

--opt uid=123

VolumeName=foo

podman volume create foo

Supported keys in [Volume] section are:

### ContainersConfModule=
Load the specified containers.conf(5) module. Equivalent to the Podman --module option.

This key can be listed multiple times.

### Copy= (default to true)
If enabled, the content of the image located at the mountpoint of the volume is copied into the volume on the first run.

### Device=
The path of a device which is mounted for the volume.

### Driver=
Specify the volume driver name. When set to image, the Image key must also be set.

This is equivalent to the Podman --driver option.

### GlobalArgs=
This key contains a list of arguments passed directly between podman and volume in the generated file. It can be used to access Podman features otherwise unsupported by the generator. Since the generator is unaware of what unexpected interactions can be caused by these arguments, it is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### Group=
The host (numeric) GID, or group name to use as the group for the volume

### Image=
Specifies the image the volume is based on when Driver is set to the image. It is recommended to use a fully qualified image name rather than a short name, both for performance and robustness reasons.

The format of the name is the same as when passed to podman pull. So, it supports using :tag or digests to guarantee the specific image version.

Special case:

•

If the name of the image ends with .image, Quadlet will use the image pulled by the corresponding .image file, and the generated systemd service contains a dependency on the $name-image.service (or the service name set in the .image file). Note: the corresponding .image file must exist.

### Label=
Set one or more OCI labels on the volume. The format is a list of key=value items, similar to Environment.

This key can be listed multiple times.

### Options=
The mount options to use for a filesystem as used by the mount(8) command -o option.

### PodmanArgs=
This key contains a list of arguments passed directly to the end of the podman volume create command in the generated file (right before the name of the volume in the command line). It can be used to access Podman features otherwise unsupported by the generator. Since the generator is unaware of what unexpected interactions can be caused by these arguments, is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### Type=
The filesystem type of Device as used by the mount(8) commands -t option.

### User=
The host (numeric) UID, or user name to use as the owner for the volume

### VolumeName=
The (optional) name of the Podman volume. If this is not specified, the default value is the same name as the unit, but with a systemd- prefix, i.e. a $name.volume file creates a systemd-$name Podman volume to avoid conflicts with user-managed volumes.

## Build units [Build]
Build files are named with a .build extension and contain a section [Build] describing the image build command. The generated service is a one-time command that ensures that the image is built on the host from a supplied Containerfile and context directory. Subsequent (re-)starts of the generated built service will usually finish quickly, as image layer caching will skip unchanged build steps.

A minimal .build unit needs at least the ImageTag= key, and either of File= or SetWorkingDirectory= keys.

Using build units allows containers and volumes to depend on images being built locally. This can be interesting for creating container images not available on container registries, or for local testing and development.

Valid options for [Build] are listed below:

### Annotation=
Add an image annotation (e.g. annotation=value) to the image metadata. Can be used multiple times.

This is equivalent to the --annotation option of podman build.

### Arch=
Override the architecture, defaults to hosts', of the image to be built.

This is equivalent to the --arch option of podman build.

### AuthFile=
Path of the authentication file.

This is equivalent to the --authfile option of podman build.

### BuildArg=
Specifies a build argument and its value in the same way environment variables are (e.g., env=value), but it is not added to the environment variable list in the resulting image's configuration. Can be listed multiple times.

This is equivalent to the --build-arg option of podman build.

### ContainersConfModule=
Load the specified containers.conf(5) module. Equivalent to the Podman --module option.

This key can be listed multiple times.

### DNS=
Set network-scoped DNS resolver/nameserver for the build container.

This key can be listed multiple times.

This is equivalent to the --dns option of podman build.

### DNSOption=
Set custom DNS options.

This key can be listed multiple times.

This is equivalent to the --dns-option option of podman build.

### DNSSearch=
Set custom DNS search domains. Use DNSSearch=. to remove the search domain.

This key can be listed multiple times.

This is equivalent to the --dns-search option of podman build.

### Environment=
Add a value (e.g. env=value) to the built image. This uses the same format as services in systemd ⟨https://www.freedesktop.org/software/systemd/man/systemd.exec.html#Environment=⟩ and can be listed multiple times.

### File=
Specifies a Containerfile which contains instructions for building the image. A URL starting with http(s):// allows you to specify a remote Containerfile to be downloaded. Note that for a given relative path to a Containerfile, or when using a http(s):// URL, you also must set SetWorkingDirectory= in order for podman build to find a valid context directory for the resources specified in the Containerfile.

Note that setting a File= field is mandatory for a .build file, unless SetWorkingDirectory (or a WorkingDirectory in the Service group) has also been set.

This is equivalent to the --file option of podman build.

### ForceRM=
Always remove intermediate containers after a build, even if the build fails (default true).

This is equivalent to the --force-rm option of podman build.

### GlobalArgs=
This key contains a list of arguments passed directly between podman and build in the generated file. It can be used to access Podman features otherwise unsupported by the generator. Since the generator is unaware of what unexpected interactions can be caused by these arguments, it is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### GroupAdd=
Assign additional groups to the primary user running within the container process. Also supports the keep-groups special flag.

This is equivalent to the --group-add option of podman build.

### IgnoreFile=
Path to an alternate .containerignore file to use when building the image. Note that when using a relative path you should also set SetWorkingDirectory=

This is equivalent to the --ignorefile option of podman build.

### ImageTag=
Specifies the name which is assigned to the resulting image if the build process completes successfully.

This is equivalent to the --tag option of podman build.

This key can be listed multiple times. The first instance will be used as the name of the created artifact when the .build file is referenced by another Quadlet unit.

### Label=
Add an image label (e.g. label=value) to the image metadata. Can be used multiple times.

This is equivalent to the --label option of podman build.

### Network=
Sets the configuration for network namespaces when handling RUN instructions. This has the same format as the --network option to podman build. For example, use host to use the host network, or none to not set up networking.

Special case:

•

If the name of the network ends with .network, Quadlet will look for the corresponding .network Quadlet unit. If found, Quadlet will use the name of the Network set in the Unit, otherwise, systemd-$name is used. The generated systemd service contains a dependency on the service unit generated for that .network unit, or on $name-network.service if the .network unit is not found. Note: the corresponding .network file must exist.

This key can be listed multiple times.

### PodmanArgs=
This key contains a list of arguments passed directly to the end of the podman build command in the generated file (right before the image name in the command line). It can be used to access Podman features otherwise unsupported by the generator. Since the generator is unaware of what unexpected interactions can be caused by these arguments, it is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### Pull=
Set the image pull policy.

This is equivalent to the --pull option of podman build.

### Retry=
Number of times to retry the image pull when a HTTP error occurs. Equivalent to the Podman --retry option.

### RetryDelay=
Delay between retries. Equivalent to the Podman --retry-delay option.

### Secret=
Pass secret information used in Containerfile build stages in a safe way.

This is equivalent to the --secret option of podman build and generally has the form secret[,opt=opt ...].

### SetWorkingDirectory=
Provide context (a working directory) to podman build. Supported values are a path, a URL, or the special keys file or unit to set the context directory to the parent directory of the file from the File= key or to that of the Quadlet .build unit file, respectively. This allows Quadlet to resolve relative paths.

When using one of the special keys (file or unit), the WorkingDirectory field of the Service group of the Systemd service unit will also be set to accordingly. Alternatively, users can explicitly set the WorkingDirectory field of the Service group in the .build file. Please note that if the WorkingDirectory field of the Service group is set by the user, Quadlet will not overwrite it even if SetWorkingDirectory is set to file or unit.

By providing a URL to SetWorkingDirectory= you can instruct podman build to clone a Git repository or download an archive file extracted to a temporary location by podman build as build context. Note that in this case, the WorkingDirectory of the Systemd service unit is left untouched by Quadlet.

Note that providing context directory is mandatory for a .build file, unless a File= key has also been provided.

### Target=
Set the target build stage to build. Commands in the Containerfile after the target stage are skipped.

This is equivalent to the --target option of podman build.

### TLSVerify=
Require HTTPS and verification of certificates when contacting registries.

This is equivalent to the --tls-verify option of podman build.

### Variant=
Override the default architecture variant of the container image to be built.

This is equivalent to the --variant option of podman build.

### Volume=
Mount a volume to containers when executing RUN instructions during the build. This is equivalent to the --volume option of podman build, and generally has the form [[SOURCE-VOLUME|HOST-DIR:]CONTAINER-DIR[:OPTIONS]].

If SOURCE-VOLUME starts with ., Quadlet resolves the path relative to the location of the unit file.

Special case:

•

If SOURCE-VOLUME ends with .volume, Quadlet will look for the corresponding .volume Quadlet unit. If found, Quadlet will use the name of the Volume set in the Unit, otherwise, systemd-$name is used. The generated systemd service contains a dependency on the service unit generated for that .volume unit, or on $name-volume.service if the .volume unit is not found. Note: the corresponding .volume file must exist.

This key can be listed multiple times.

## Image units [Image]
Image files are named with a .image extension and contain a section [Image] describing the container image pull command. The generated service is a one-time command that ensures that the image exists on the host, pulling it if needed.

Using image units allows containers and volumes to depend on images being automatically pulled. This is particularly interesting when using special options to control image pulls.

Valid options for [Image] are listed below:

Since the generator is unaware of what unexpected interactions can be caused by these arguments, it is not recommended to use this option.

The format of this is a space separated list of arguments, which can optionally be individually escaped to allow inclusion of whitespace and other control characters.

This key can be listed multiple times.

### Image=
The image to pull. It is recommended to use a fully qualified image name rather than a short name, both for performance and robustness reasons.

The format of the name is the same as when passed to podman pull. So, it supports using :tag or digests to guarantee the specific image version.

### ImageTag=

## Artifact units [Artifact]

### WARNING: Experimental Unit
This unit is considered experimental and still in development. Inputs, options, and outputs are all subject to change.

Artifact units are named with a .artifact extension and contain a [Artifact] section describing the container artifact pull command. The generated service is a one-time command that ensures that the artifact exists on the host, pulling it if needed.

Using artifact units allows containers to depend on artifacts being automatically pulled. This is particularly useful for managing artifacts that containers need to mount or access, the Artifact key is mandatory inside of the [Artifact] unit.

Require HTTPS and verification of certificates when contacting registries.

This is equivalent to the Podman --tls-verify option.

## Quadlet section [Quadlet]
Some quadlet specific configuration is shared between different unit types. Those settings can be configured in the [Quadlet] section.

Valid options for [Quadlet] are listed below:

[Quadlet] options

Description

DefaultDependencies=false

Disable implicit network dependencies to the unit

### DefaultDependencies=
Add Quadlet's default network dependencies to the unit (default is true).

When set to false, Quadlet will not add a dependency (After=, Wants=) to network-online.target/podman-user-wait-network-online.service to the generated unit.

Note, this option is set in the [Quadlet] section. The systemd [Unit] section has an option with the same name but a different meaning.

## EXAMPLES
Example test.container:

```
[Unit]
Description=A minimal container
[Container]
# Use the centos image
Image=quay.io/centos/centos:latest
# Use volume and network defined below
Volume=test.volume:/data

# In the container we just run sleep
Exec=sleep 60
[Service]
# Restart service when sleep finishes
Restart=always
# Extend Timeout to allow time to pull the image

ImageTag=localhost/imagename
# Set the working directory to the path of the unit file,
# expecting to find a Containerfile/Dockerfile
# + other files needed to build the image
SetWorkingDirectory=unit
# Set build arguments VERSION and DEBUG
BuildArg=VERSION=1.0

          DEBUG=false
```

Example s3fs.volume:

For further details, please see the s3fs-fuse project. Remember to read the FAQ

NOTE: Enabling the cache massively speeds up access and write times on static files/objects.

However, use_cache is UNBOUNDED!

Be careful, it will fill up with any files accessed on the s3 bucket through the file system.

Please remember to set S3_BUCKET, PATH, AWS_REGION. CACHE_DIRECTORY should be set up by systemd

```
[Service]
CacheDirectory=s3fs
ExecStartPre=/usr/local/bin/aws s3api put-object --bucket ${S3_BUCKET} --key ${PATH}/
[Volume]
Device=${S3_BUCKET}:/${PATH}
Type=fuse.s3fs
VolumeName=s3fs-volume
Options=iam_role,endpoint=${AWS_REGION},use_xattr,listobjectsv2,del_cache,use_cache=${CACHE_DIRECTORY}
# `iam_role` assumes inside EC2, if not, Use `profile=` instead

title: selinux_config(5)

text:
# selinux_config(5)

## NAME
config - The SELinux sub-system configuration file.

## DESCRIPTION
The SELinux config file controls the state of SELinux regarding:

1.

The policy enforcement status - enforcing, permissive or disabled.

2.

The policy name or type that forms a path to the policy to be loaded and its supporting configuration files.

3.

How SELinux-aware login applications should behave if no valid SELinux users are configured.

4.

Whether the system is to be relabeled or not.

The entries controlling these functions are described in the FILE FORMAT section.

The fully qualified path name of the SELinux configuration file is /etc/selinux/config.

If the config file is missing or corrupt, then no SELinux policy is loaded (i.e. SELinux is disabled).

The sestatus (8) command and the libselinux function selinux_path (3) will return the location of the config file.

## FILE FORMAT
The config file supports the following parameters:

SELINUX = enforcing | permissive | disabled

SELINUXTYPE = policy_name

REQUIRESEUSERS = 0 | 1

AUTORELABEL = 0 | 1

Where:

SELINUX

This entry can contain one of three values: enforcing

SELinux security policy is enforced.

permissive

SELinux security policy is not enforced but logs the warnings (i.e. the action is allowed to proceed).

disabled

No SELinux policy is loaded. This option was used to disable SELinux completely, which is now deprecated. Use the selinux=0 kernel boot option instead (see selinux(8)).

The entry can be determined using the sestatus(8) command or selinux_getenforcemode(3).

SELINUXTYPE

The policy_name entry is used to identify the policy type, and becomes the directory name of where the policy and its configuration files are located. The entry can be determined using the sestatus(8) command or selinux_getpolicytype(3).

The policy_name is relative to a path that is defined within the SELinux subsystem that can be retrieved by using selinux_path(3). An example entry retrieved by selinux_path(3) is:

/etc/selinux/

The policy_name is then appended to this and becomes the 'policy root' location that can be retrieved by selinux_policy_root_path(3). An example entry retrieved is:

/etc/selinux/targeted

The actual binary policy is located relative to this directory and also has a policy name pre-allocated. This information can be retrieved using selinux_binary_policy_path(3). An example entry retrieved by selinux_binary_policy_path(3) is:

/etc/selinux/targeted/policy/policy

The binary policy name has by convention the SELinux policy version that it supports appended to it. The maximum policy version supported by the kernel can be determined using the sestatus(8) command or security_policyvers(3). An example binary policy file with the version is:

/etc/selinux/targeted/policy/policy.24

REQUIRESEUSERS

This optional entry can be used to fail a login if there is no matching or default entry in the seusers(5) file or if the seusers file is missing. It is checked by getseuserbyname(3) that is called by SELinux-aware login applications such as PAM(8).

If set to 0 or the entry missing:

getseuserbyname(3) will return the GNU / Linux user name as the SELinux user.

If set to 1:

getseuserbyname(3) will fail.

The getseuserbyname(3) man page should be consulted for its use. The format of the seusers file is shown in seusers(5).

AUTORELABEL

This is an optional entry that allows the file system to be relabeled. If set to 0 and there is a file called .autorelabel in the root directory, then on a reboot, the loader will drop to a shell where a root login is required. An administrator can then manually relabel the file system.

If set to 1 or no entry present (the default) and there is a .autorelabel file in the root directory, then the file system will be automatically relabeled using fixfiles -F restore

In both cases the /.autorelabel file will be removed so that relabeling is not done again.

## EXAMPLE
This example config file shows the minimum contents for a system to run SELinux in enforcing mode, with a policy_name of 'targeted':

SELINUX = enforcing

SELINUXTYPE = targeted

sestatus.conf

title: sestatus.conf(5)

summary: The sestatus(8) configuration file.

text:
# sestatus.conf(5)

## NAME
sestatus.conf - The sestatus(8) configuration file.

## DESCRIPTION
The sestatus.conf file is used by the sestatus(8) command with the -v option to determine what file and process security contexts should be displayed.

The fully qualified path name of the configuration file is:

/etc/sestatus.conf

The file consists of two optional sections as described in the FILE FORMAT section. Whether these exist or not, the following will always be displayed:

The current process context

The init process context

The controlling terminal file context

## FILE FORMAT
The format consists of two optional sections as follows:

[files]

file_name

[file_name]

... [process]

executable_file_name

[executable_file_name]

...

Where:

[files] The start of the file list block.

file_name One or more fully qualified file names, each on a new line will that will have its context displayed. If the file does not exist, then it is ignored. If the file is a symbolic link, then sestatus -v will also display the target file context.

[process]

The start of the process list block.

executable_file_name One or more fully qualified executable file names that should it be an active process, have its context displayed. Each entry is on a new line.

## EXAMPLE
\# /etc/sestatus.conf

[files]

/etc/passwd

/etc/shadow

/bin/bash

/bin/login

/lib/libc.so.6

/lib/ld-linux.so.2

/lib/ld.so.1

## NAME
setrans.conf - translation configuration file for MCS/MLS SELinux systems

## DESCRIPTION
The /etc/selinux/{SELINUXTYPE}/setrans.conf configuration file specifies the way that SELinux MCS/MLS labels are translated into human readable form by the mcstransd daemon. The default policies support 16 sensitivity levels (s0 through s15) and 1024 categories (c0 through c1023). Multiple categories can be separated with commas (c0,c1,c3,c5) and a range of categories can be shortened using dot notation (c0.c3,c5).

### Keywords
Base

once a base is declared, subsequent sensitivity label definitions will have all modifiers applied to them during translation. Sensitivity labels defined before the base declaration are immediately cached and no modifiers will be applied these are used as direct translations.

Default

defines the category bit range that will be used for inverse bits.

Domain

creates a new domain with the supplied name.

Include

read and process the contents of the specified configuration file.

Join

defines a character used to separate members of a modifier group when more than one is specified (ex. USA/AUS).

ModifierGroup

a means of grouping category bit definitions by how they modify the sensitivity label.

Prefix

word(s) that may proceed member(s) of a modifier group (ex. REL USA).

Suffix

word(s) that may follow member(s) of a modifier group (ex. USA EYES ONLY).

Whitespace

defines the set of acceptable white space characters that may be used in label being translated.

### Sensitivity Level Definition Examples
s0=SystemLow

defines a translation of s0 (the lowest sensitivity level) with no categories to SystemLow.

s15:c0.c1023=SystemHigh

defines a translation of s15:c0.c1023 to SystemHigh. c0.c1023 is shorthand for all categories. A colon separates the sensitivity level and categories.

s0-s15:c0.c1023=SystemLow-SystemHigh

defines a range translation of s0-s15:c0.c1023 to SystemLow-SystemHigh. The two range components are separated by a dash.

s0:c0=PatientRecord

defines a translation of sensitivity s0 with category c0 to PatientRecord.

s0:c1=Accounting

defines a translation of sensitivity s0 with category c1 to Accounting.

s2:c1,c2,c3=Confidential3Categories

s2:c1.c3=Confidential3Categories

both define a translation of sensitivity s2 with categories c1, c2 and c3 to Confidential3Categories.

s5=TopSecret

defines a translation of sensitivity s5 with no categories to TopSecret.

### Constraint Examples
c0!c1

if category bits 0 and 1 are both set, the constraint will fail and the original context will be returned.

c5.c9>c1

if category bits 5 through 9 are set, bit 1 must also be set or the constraint will fail and the original context will be returned.

s1!c5,c9

if category bits 5 and 9 are set and the sensitivity level is s1, the constraint will fail and the original context will be returned.
