podman-generate-systemd — Generate systemd unit file(s) for a container. Not supported for the remote client

Synopsis

podman generate systemd [options] container|pod

Description

podman generate systemd will create a systemd unit file that can be used to control a container or pod. By default, the command will print the content of the unit files to stdout.

Note that this command is not supported for the remote client.

Options

--files, -f
Generate files instead of printing to stdout.  The generated files are named {container,pod}-{ID,name}.service and will be placed in the current working directory.
--name, -n
Use the name of the container for the start, stop, and description in the unit file
--new
Create a new container via podman-run instead of starting an existing one.  This option relies on container configuration files, which may not map directly to podman CLI flags; please review the generated output carefully before placing in production.
--timeout, -t=value
Override the default stop timeout for the container with the given value.
--restart-policy=policy
Set the systemd restart policy.  The restart-policy must be one of: "no", "on-success", "on-failure", "on-abnormal", "on-watchdog", "on-abort", or "always".  The default policy is on-failure.

Examples

Create and print a systemd unit file for a container running nginx with an always restart policy and 1-second timeout to stdout.

$ podman create --name nginx nginx:latest
$ podman generate systemd --restart-policy=always -t 1 nginx

Create systemd unit files for a pod with two simple alpine containers. Note that these container services cannot be started or stopped individually via systemctl; they are managed by the pod service. You can still use systemctl status or journalctl to examine them.

$ podman pod create --name systemd-pod
$ podman create --pod systemd-pod alpine top
$ podman create --pod systemd-pod alpine top
$ podman generate systemd --files --name systemd-pod
