To install it, use: ansible-galaxy collection install containers.podman.

To use it in a playbook, specify: containers.podman.podman_container.

New in version 1.0.0: of containers.podman

Synopsis

  • Start, stop, restart and manage Podman containers

blkio_weight

integer

Block IO weight (relative weight) accepts a weight value between 10 and 1000

list / elements=string

List of capabilities to drop from the container.

cgroup_parent

path

Path to cgroups under which the cgroup for the container will be created. If the path is not absolute, the path is considered to be relative to the cgroups path of the init process. Cgroups will be created if they do not already exist.

cgroupns

string

Path to cgroups under which the cgroup for the container will be created.

cgroups

string

Determines whether the container will create CGroups. Valid values are enabled and disabled, which the default being enabled. The disabled option will force the container to not create CGroups, and thus conflicts with CGroup options cgroupns and cgroup-parent.

cidfile
