Cloud Shell runs on Oracle Linux 8

Most preinstalled tools and utilities have been upgraded to newer versions.

Docker Engine is no longer installed in Oracle Linux 8 (OL8) Cloud Shell. Instead, it has been replaced by Podman, which provides a similar container management experience with a daemonless architecture. For backward compatibility purposes, OL8 Cloud Shell has a command "docker" available which is a wrapper of the command "podman". You can run the command "podman" or "docker" to run containers with commands largely compatible with Docker. For more information about podman, see: https://docs.oracle.com/en/operating-systems/oracle-linux/podman/index.html.
