Podman Release 1.5.0

podman logo

Podman has gone 1.5!

Podman 1.5.0 has been released! We’ve made major improvements to podman exec, podman generate kube, and rootless containers in this release. Stability has also been a focus, and we’ve fixed over 30 bugs and several performance issues. The new 1.5.0 release is available for Fedora and Ubuntu right now!

With this new release, Podman has picked up a number of improvements to core container functionality. The podman exec command has been completely reworked, including improved handling for attaching to containers. Expect to see more work on exec in future releases. CGroups have also seen major work, with support for CGroup namespaces via the --cgroupns flag to podman create and podman run, and support for CGroups v2 when using the crun OCI runtime - more details here. The podman generate kube command has also been improved and now includes volumes mounted into containers. Finally, we’ve addressed several memory leaks and other performance issues, and Podman should be much more responsive on systems under high load.

Rootless containers have also been improved, featuring improved handling for privileged containers and the ability to use container health checks. Podman now has experimental support for running rootless containers with a single UID and GID using the new ignore_chown_errors storage option. This allows Podman to be run without the newuidmap and newgidmap binaries, and removes the need for any elevated privileges to start rootless containers. This approach is more limited (but more secure) than normal rootless containers.

As always, please visit our release notes on GitHub to see the full changelog.
