Manage podman with systemd

Submitted by gill on Tue, 01/03/2023 - 17:42

After getting the containers running you can have systemd start and stop them for you.

$ podman pull docker.io/library/httpd

$ podman run -dt -p 8080:80/tcp --name httpd docker.io/library/httpd

Now you can create systemd files:

$ cd $HOME/.config/systemd/user

$ podman generate systemd --new --files --name httpd

The podman generate command creates a systemd service file named container-httpd.service. Reload the daemon to read the new file:

$ systemctl --user daemon-reload

Stop the running container
