Buildah version 1.19.0 Release Announcement

We’re pleased to announce the release of Buildah version 1.19.0, which is now available from GitHub for any Linux distro. We are shipping this release on Fedora 32 & 33 and RHEL 8.4. 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 the notable enhancements: The --stdin and --from options have been added to the bud command, further support for multi-arch images were added to the bud and commit commands, container image short name aliasing is now enabled by default, a few speed improvements to the build process, and a number of bug fixes.

• When using the bud command, users can now employ the --stdin option to feed input into the build process. See the buildah bud man page for details.
• A new --from option has been added to the bud command. When used, the value in the first FROM declaration in the Containerfile is overridden by the argument passed to the --from option. See the buildah bud man page for details.
• Added support to the ‘bud and the commit commands for the –manifest option to allow the building of multi-arch images. See the buildah bud and buildah commit` man pages for details.
• Short-name aliasing has been enabled by default when running Buildah in a terminal. When pulling an image by a short name, Buildah may now present a prompt to choose which image to pull. Please refer to a recent blog post for details.

This release comprises changes made for v1.18.0 through v1.19.0.

Release Changes

Changes for v1.19.0

• The buildah inspect command can now inspect manifests.
• The buildah push command can now push manifests lists and digests.
• Fixed handling of TMPDIR environment variable to now work as designed.
• Added support to the ‘bud and the commit1 commands for the --manifest option to allow the building of multi-arch images. See the buildah bud and buildah commit man pages for details.
• When mounting over a destination directory in a container, the mode is now preserved on the destination directory.
• Enabled the --arch and --os options to be used in place of the --override-os and override-arch options to select architecture and os. The --override-os and override-arch options are still usable but are deprecated and no longer listed in the man pages.
• Attempting to ADD device nodes to a working container when running as an unprivileged user in rootless mode will now quietly ignore the device nodes and appear to succeed again, matching the behavior of versions before 1.16, instead of triggering an error.
• The buildah rmi --prune now works as expected.
• When using the bud command, users can now employ the --stdin option to feed input into the build process. See the buildah bud man page for details.
• A spurious error log message on failure to mount on /sys file systems when running rootless has been changed to an info log.
• Switched references of the /var/run directory to the /run directory. The /var/run directory is a legacy directory that has been replaced by the /run directory. In some environments, warnings were raised due to the use of the /var/run directory.
• A new --from option has been added to the bud command. When used, the value in the first FROM declaration in the Containerfile is overridden by the argument passed to the --from option. See the buildah bud man page for details.
• Several changes to the copier code were made to handle replacing directories with non-directories and a few efficiency changes.
• Added the U volume flag to chown source volumes within the container.
• Rootless operations now use the correct isolation, “rootless”, instead of “oci”.
• Enable short-name aliasing of container images by default.
• When calling the manifest create or manifest add commands, the registry is now checked before the local images.
• Added further container information to the .containerenv file.
• Added the --ignorefile and --contextdir options to the add, bud, and create commands. Using these two options allows for an alternative location of the context directory and the .dockerignore file.
• Fixed a crash on invalid filter commands.
• A few shebangs in some of the scripts and examples were non-portable and have been corrected.
• RUN instructions in builds will no longer run attached to a pseudo-terminal unless the --stdin flag is added.
• The diffID for a mapped-layer is now computed when creating the image source to avoid a failure during container creation.
• Bump to v1.19.0-dev
