Oracle Linux: Install Podman on Oracle Linux 8 (Doc ID 2869144.1)

Last updated on MAY 12, 2022

Applies to:

Linux OS - Version Oracle Linux 8.0 and later
Oracle Cloud Infrastructure - Version N/A and later
Linux x86-64

Goal

Podman provides a lightweight utility to run and manage Open Container Initiative (OCI) compatible containers. As such, a Podman deployment can re-use existing container images that are designed for Kubernetes, Oracle Container Runtime for Docker, and Oracle Linux Cloud Native Environment.

Podman is also intended as a drop-in replacement for Oracle Container Runtime for Docker, so the command-line interface (CLI) functions the same way if the podman-docker package is installed.

Unlike Oracle Container Runtime for Docker, Podman does not require a running daemon to function. Also, there is no dependency on the Unbreakable Enterprise Kernel (UEK). Containers run correctly on systems that are running either the Red Hat Compatible Kernel (RHCK) or the UEK release. In addition, Podman enables containers to start and run without root permissions.

As much as possible, Podman and its related utilities, Buildah and Skopeo, are designed to work independently of each other. For example, Buildah has no dependency on Podman, which means it is possible to separate the container build infrastructure from environments in which the containers are intended to run. You can install the buildah package on the same system that you run Podman; or, you can install the package on an alternate system, if required. Similarly, you can install Skopeo separate from the other utilities, according to your specific requirements.
