bootc-container-inspect(8)

NAME()

bootc-container-inspect - Output JSON to stdout containing the container image metadata

SYNOPSIS

bootc container inspect

DESCRIPTION

Output JSON to stdout containing the container image metadata.

OUTPUT

The command outputs a JSON object with the following fields:

kargs: An array of kernel arguments embedded in the container image.
kernel: An object containing kernel information (or null if no kernel is found):

version: The kernel version identifier. For vmlinuz kernels, this is derived from the /usr/lib/modules/<version> directory name (equivalent to uname -r). For UKI images, this is the UKI filename without the .efi extension - which should usually be the same as the uname.
unified: A boolean indicating whether the kernel is packaged as a UKI (Unified Kernel Image).
