12.8. Automatically updating containers using Podman

Procedure

1. Start a myubi container based on the registry.access.redhat.com/ubi10/ubi-init image:

   # podman run --label "io.containers.autoupdate=image" \
   --name myubi -dt registry.access.redhat.com/ubi10/ubi-init top
   bc219740a210455fa27deacc96d50a9e20516492f1417507c13ce1533dbdcd9d

2. Optional: List containers that are running or have exited:

   # podman ps -a
   CONTAINER ID  IMAGE                                            COMMAND  CREATED         STATUS             PORTS   NAMES
   76465a5e2933  registry.access.redhat.com/10/ubi-init:latest  top      24 seconds ago  Up 23 seconds ago          myubi

3. Generate a systemd unit file for the myubi container:

   # podman generate systemd --new --files --name myubi
   /root/container-myubi.service

4. Copy unit files to /usr/lib/systemd/system for installing it as a root user:

   # cp -Z ~/container-myubi.service /usr/lib/systemd/system

5. Reload systemd manager configuration:

   # systemctl daemon-reload

6. Start and check the status of a container:

   # systemctl start container-myubi.service
   # systemctl status container-myubi.service

7. Auto-update the container:

   # podman auto-update
