It is really easy to configure a user-space systemd autostart for Containers on OpenSuSE MicroOS with Podman-Compose.
When your Podman Container YourContainerService is running, then generate the systemd user unit:
podman generate systemd --new YourContainerService > ~/.config/systemd/user/YourContainer.service
Then enabe the systemd user unit for autostart:
systemctl --user daemon-reload
systemctl --user start YourContainer.service
If required, enable the systemd autostart:
systemctl --user enable YourContainer.service
If you are running more then one Container over Podman Compose, please add all the container service units, over the Container Name.
Easy. Thats it!
