We’re pleased to announce the release of Buildahversion 1.22.0, which is now available from GitHub for any Linux distro. We are shipping this release on Fedora 32, 33 & 34, 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:
To be more inclusive, the “master” branch has been renamed to “main” in the GitHub repository. A number of changes throughout the project were made to account for this.
A number of changes were made to the Dockerfiles and procedures that build the Buildah container images that are on quay.io to allow them to run Buildah more easily within them, especially as a rootless user.
A dangling image is now considered dangling if it is “untagged” and does not have children. This now matches the definition used by Docker.
This release comprises changes made for v1.21.0 through v1.22.0 and will be included in Podman v3.3.
Changes for v1.22.0
Changes were made to allow dst and destination to be used for targets in secret mounts.
Previously, a dangling image was an “untagged” image. This has been refined to an “untagged” image without children which emulates Docker’s definition.
An invalid ADD --chown <value> command in a Containerfile would not error 3380. This has been corrected.
Fixed a CVE where environment values could leak into intermediate processes.
Reuse code from containers/common/pkg/parse.
Excludes exceptions beginning with / or ./ in a .dockerignore file were being ignored [3272}(https://github.com/containers/buildah/issues/3272) and this has been corrected.
No longer set 0_NONBLOCK on stdin to address 3152.
The methods used to create a default network in a container have been moved to containers/common.
Added the --env and --workingdir flags to the run command. See the run man page for details.
Added the --json flag to the mount and version commands. See the mount and version man page for details.
The copy and add commands can now use a .containerignore file 3303.
When copying a single file to the workdir, the workdir is no longer mistakenly overwritten podman#10671.
The way that the auth.json file was searched for when running as a rootless user was different for a variety of commands 3259. This has been corrected to search for the file in the appropriate location.
Bump to v1.21.1-dev
