Containers: Environment Variables and Persistent Storage

A worker container reads its mode from an environment variable and writes its log under /data. Last time it ran, its data vanished with the container. The brief in /root/case/brief.txt gives the name, the mode and the host directory. Run it so the setting is passed in and its data lands on the host. Lab machines have no internet access, so the image is already in podman's local store, as if you had pulled it.
