Parameters

Parameter	Comments
annotation dictionary	Add an annotation to the container. The format is key value, multiple times.
authfile path	Path of the authentication file. Default is ${XDG_RUNTIME_DIR}/containers/auth.json (Not available for remote commands) You can also override the default path of the authentication file by setting the REGISTRY_AUTH_FILE environment variable. export REGISTRY_AUTH_FILE=path
blkio_weight integer	Block IO weight (relative weight) accepts a weight value between 10 and 1000
blkio_weight_device dictionary	Block IO weight (relative device weight, format DEVICE_NAME[:]WEIGHT).
cap_add aliases: capabilities list / elements=string	List of capabilities to add to the container.
cap_drop 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 path	Write the container ID to the file
cmd_args list / elements=string	Any additional command options you want to pass to podman command, cmd_args - [‘–other-param’, ‘value’] Be aware module doesn’t support idempotency if this is set.
command raw	Override command of container. Can be a string or a list.
conmon_pidfile path	Write the pid of the conmon process to a file. conmon runs in a separate process than Podman, so this is necessary when using systemd to restart Podman containers.

Use the recreate option to force the re-creation of the matching container. started - Asserts there is a running container matching the name and any provided configuration. If no container matches the name, a container will be created and started. Use recreate to always re-create a matching container, even if it is running.
