## NAME
|
|
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
|
|
|
|
**--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
