RHEL 8.5 delivers key container improvements

RHEL 8.5, the newest version of Red Hat Enterprise Linux (RHEL), is out. As Joe Brockmeier, Red Hat Blogs’ Editorial Director, said, “Whether you’re deploying RHEL on-prem, in the public cloud, at the edge — or all of the above — RHEL 8.5 has improvements that users will be eager to dig into.” 

He’s not wrong.

In particular, as we continue to move to a container and Kubernetes-based world, RHEL 8.5 comes with significant container improvements. These include: 

Containerized Podman: The RHEL 8 Podman container image is now generally available and can help unlock the usage of Podman in cloud continuous integration/delivery (CI/CD) systems, on Windows Subsystem for Linux (WSL) 2, under Docker Desktop on macOS, and (of course) on RHEL 6, 7 and 8. You can use the Podman container image to help develop and run other container images. 

Verify container image signatures by default: In RHEL 8.5, users can pull container images with confidence. Out of the box, RHEL 8.5 will check container image signatures to verify that they are, in fact, from Red Hat and haven’t been tampered with or manipulated. 

Native OverlayFS as a Rootless container user: RHEL 8.5 offers better performance when building and running rootless containers, with native support for OverlayFS.
