Buildah version 1.23.0 Release Announcement

We’re pleased to announce the release of Buildah version 1.23.0, which is now available from GitHub for any Linux distro. We are shipping this release on Fedora 34 & 35, and RHEL 8.5. Buildah will also be shipped on CentOS, OpenSUSE, and Ubuntu soon. In addition, container images will be available at https://quay.io/repository/buildah/stable and https://quay.io/repository/containers/buildah.

The Buildah project has continued to grow over the past several weeks, welcoming several new contributors to the mix. This release features notable enhancements:

• Support has been added for rootless containers to use overlay mounts.
• An epoch time field has been added to the container images created by Buildah.
• The bud command has been renamed to build. An alias for bud was created for backward compatibility and to not break existing scripts.
• The platform option for build can now take multiple values.
• The login and logout commands now accept repositories as Podman does.

This release comprises changes made for v1.23.0 and will be included in Podman v3.3.1
