So, you’ve been using Linux containers, and you want to check out what new features are available in Red Hat Enterprise Linux 8 Beta? We’ll provide a quick runthrough of some of the tools you’ll have available to work with containers.

This post will assume you can get a RHEL 8 Beta system installed - but, if you need a little guidance, check out the installation guide.

If you’re a container veteran, you may have developed a habit of tailoring your systems by installing the “docker” package. On your brand new RHEL 8 Beta system, the first thing you’ll likely do is go to your old friend yum. You’ll try to install the docker package, but to no avail. If you are crafty, next, you’ll search and find this package:

podman-docker.noarch : "package to Emulate Docker CLI using podman."

What is this Podman we speak of? The docker package is replaced by the Container Tools module, which consists of Podman, Buildah, Skopeo and several other tidbits. There are a lot of new names packed into that sentence so, let’s break them down.

  • Module - basically, a group of software that is released together in a single life cycle. For more see: Introducing Application Streams (AppStreams) in RHEL 8. Also, see the upstream Fedora Modularity documentation.

  • Podman -  Simpler, daemon-less tool that provides a command line experience. If you can use the docker cli, you already know how to use podman.  For more see this introduction by Doug Tidwell.

  • Buildah - powerful build tool which is designed to provide control over how image layers are committed, and how data is accessed during builds. For more, check out these tutorials.

  • Skopeo - flexible utility which enables moving, signing, and verifying of container images between registry servers and container hosts.  For a quick introduction, see this tutorial.

These tools are compatible with the OCI specifications which means they can find, run, build and share containers with other tools that target the OCI standards including Docker CE, Docker EE, Kata Containers, CRI-O, and other container engines, registries, and tools. You can build with Buildah, and run with CRI-O. You can copy images from an AWS container registry to a local Podman instance. The OCI standards offer greater flexibility and choice. So, how might one get these new tools in Red Hat Enterprise Linux 8 Beta? Run this command on your Red Hat Enterprise Linux 8 Beta system:

yum module install -y container-tools

When this command completes, you will have all three tools installed and ready to go. Experiment, have fun, and let us know what you think. Once you have your packages installed, checkout the RHEL 8 Beta documentation to get started with podman, buildah, and skopeo: Building, running, and managing containers.

As you find features you think would be useful, or even bugs, please let us know. To file a feature or bug during the life of Red Hat Enterprise Linux 8 Beta, file an issue on Red Hat's Bugzilla instanceThis link will take you directly to where you need to go, but you will need to create an account first, if you don't already have one.
