I created an unit file, with the following lines to start-up a podman container. Unfortunately, right after starting up, journalctl -xe tells me service not needed, shutting down, service shuts down. podman ps --all says exited (0), hence, it is a regular stop.

[Unit]
Description=Service for auto-start the Podman NGINX Container
After=syslog.target
After=network.target

[Service]
Type=simple
User=root
Group=root

ExecStart=podman start nginx
ExecStop=podman stop nginx

[Install]
WantedBy=multi-user.target

I tried also some variants with StopWhenUnneeded=false, which made no difference.

System is RedHat8. The official RedHat-description to solve this didn't work.

There is a Podman command for creating a systemd service unit file

podman generate systemd --name --new nginx.

See the podman generate systemd man page.

Here is an example:

[root@asus ~]# podman create --name nginx -p 80:80 docker.io/library/nginx
7844db33bf66233f71c74ce0d43e590a8478b087198dfc276477baaf20a9b503
[root@asus ~]# podman generate systemd --name --new nginx > /etc/systemd/system/nginx.service
[root@asus ~]# systemctl daemon-reload
[root@asus ~]# systemctl start nginx.service
[root@asus ~]# curl localhost:80
