Zun CLI man page

SYNOPSIS

Zun operation use zun command, and also support use openstack command.

zun [options] <command> [command-options]

openstack appcontainer <command> [command-options]

DESCRIPTION

The zun command line utility interacts with OpenStack Containers Service (Zun).

In order to use the CLI, you must provide your OpenStack username, password, project (historically called tenant), and auth endpoint. You can use configuration options --os-username, --os-password, --os-tenant-name or --os-tenant-id, and --os-auth-url or set corresponding environment variables:

export OS_USERNAME=user
export OS_PASSWORD=pass
export OS_PROJECT_NAME=myproject
export OS_AUTH_URL=http://auth.example.com:5000/v3
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_DOMAIN_ID=default


OPTIONS

To get a list of available commands and options run:

zun help


To get usage and options of a command:

zun help <command>


You can also use openstack command as follow.

To get a list of available commands run:

Reference

The zunclient Python API

Usage

First create a client instance with your credentials:

>>> from zunclient import client
>>> zun = client.Client(VERSION, auth_url=AUTH_URL, username=USERNAME,
...                     password=PASSWORD, project_name=PROJECT_NAME,
...                     user_domain_name='default',
...                     project_domain_name='default')


Here VERSION can be a string or zunclient.api_versions.APIVersion obj. If you prefer string value, you can use 1 or 1.X (where X is a microversion).

Alternatively, you can create a client instance using the keystoneauth session API:

>>> from keystoneauth1 import loading
>>> from keystoneauth1 import session

If you have PROJECT_NAME instead of a PROJECT_ID, use the project_name parameter. Similarly, if your cloud uses keystone v3 and you have a DOMAIN_NAME or DOMAIN_ID, provide it as user_domain_(name|id) and if you are using a PROJECT_NAME also provide the domain information as project_domain_(name|id).

Then call methods on its managers:

>>> zun.containers.list()
[<Container {...}>]
>>> zun.containers.run(name="my-container", image='nginx')
<Container {...}>
