Managing Containers on RHEL 8 Using podman

In this lab, you're an otherwise experienced systems operator who has been tasked with working through how root-less containers can be configured on your server. You'll be querying for what container images are available, pulling container images, performaing basic operations on them, monitoring the state and operation of the containers, and testing for running services on the containers. You'll then configure the user environment for running a container as a `systemd` service, pull and execute a container with custom parameters, and then generate a custom `systemd` service unit and enable it to run automatically on system boot. Finally, you'll test that everything is set for being persistent upon reboot, then reboot and verify that the custom `systemd` service is verifiably persistent, and monitor it briefly for continued function. *This course is not approved or sponsored by Red Hat.*
