Buildah version 1.41.0 Release Announcement

We’re pleased to announce the release of Buildah version 1.41.0, which is now available from GitHub for any Linux distro. We are shipping this release on Fedora 41 and Fedora 42. 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 changes:

A number of changes have been made to allow for “reproducible builds”, which, in specific scenarios, should reduce the pull time of images.
The --inherit-annotations, --source-date-epoch, --rewrite-timestamp, and --unsetannotation commands have been added to the build command. See the build man page for more details.
The --link option on the COPY and ADD commands in a Containerfile now fully supports layered build caching.

This release comprises changes made for v1.41.0 and will be included in Podman v5.6.

Buildah version 1.37.0 Release Announcement

We’re pleased to announce the release of Buildah version 1.37.0, which is now available from GitHub for any Linux distro. We are shipping this release on Fedora 39 and Fedora 40. 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 changes:

When building an image using buildah build, the contents of directories marked as volumes (defined by VOLUME instructions), whether as part of the build, or inherited from a base image, will no longer be saved before, and restored after, processing RUN instructions. The --compat-volumes flag can be used to re-enable this behavior.
The config command now supports the --healthcheck-start-interval option, which allows the user to specify the time between health checks during the start period.
When buildah copy is given the --from option, the ownership of items being copied from other images or containers will be preserved by default for better consistency with handling of the COPY instruction in Dockerfiles. The previous behavior can be forced by adding the --chown=0:0 flag,

This release comprises changes made for v1.37.0 and will be included in Podman v5.2.

Fix secret mounts for environment variables when using chroot isolation by @jonahbull in #5544
imagebuildah: Support custom image reference lookup for cache push/pull by @aaronlehmann in #5532
The config command now supports the --healthcheck-start-interval option, which allows the user to specify the time between healthchecks during the start period by @flouthoc in #5472
A nil pointer reference on that could occur on FreeBSD systems when using the buildah run command has been corrected by @dfr in #5580
Add some NetBSD support by @coypoop in #5559
When buildah copy is given the --from option, the ownership of items being copied from other images or containers will be preserved by default for better consistency with handling of the COPY instruction in Dockerfiles. The previous behavior can be forced by adding the --chown=0:0 flag, by @nalind in #5597
Images built using buildah build without --layers=true will describe their base image in the history entry for the first instruction that was processed, rather than the last instruction by @nalind in #5595
If the “FROM” command was used with a --platform option, it is now included when logging the instruction by @nalind in #5599
Unrecognized values for the --pull command line flag are no longer silently treated as if they were “missing” by @nalind in #5605
Change default for podman build to –pull missing by @rhatdan in #5583
When building an image using buildah build, the contents of directories marked as volumes (defined by VOLUME instructions), whether as part of the build, or inherited from a base image, will no longer be saved before, and restored after, processing RUN instructions. The --compat-volumes flag can be used to re-enable this behavior by @nalind in #5604

Overall Miscellaneous Changes

The prune command has been added to clean intermediate images as well as the build and mount cache.
Added support for the --group-add option to the from and build commands. One useful feature of this, it to use the –group-add keep-groups option, which allows rootless users to take advantage of their group access to file and devices mounted into the build containers.
The --cache-from and --cache-to options for the build command now allow for multiple sources. This can be used to improve the speed of builds, especially in CI/CD environments.

This release comprises changes made for v1.28.1 and v1.28.2 and will be included in Podman v4.4.

Release Changes

Changes for v1.29.0

Fixed an issue with the build command when using the --mount option with the RUN command. In some cases, the correct build stage was not being used (#4522).
When the --env command line flag conflicts with an ENV instruction in a Containerfile, the Containerfile’s value is now the one that is recorded in the output image.
Multiple --label command line flags now generate only one history entry in the output image.
The --env command line flag now generates a history entry in the output image.
Added support for the --group-add option to the from and build commands which assign additional groups to the primary user running within the container.

An error has been addressed that prevented the --secret type=env option from working when running the build command within a container.
Mult-stage builds now resolve the named image appropriately if a build arg is the same name.
When the build command used a RUN --mount=type=bind command to a previous stage, the contents were not accessible of the stage had been cached (#4375). This has been fixed.
An issue with the build ---cache-from not working properly with the ARG command has been corrected (#4315).
Locking mechanisms used for cacheing were simplified within the code and an issue was locks with multiple mounts was fixed..
Simplify the interface of GetCacheMount and getCacheMount.
When using the --mount=type=secret option for the Containerfile RUN command, relative paths from the configured work directory can now be specified.

Buildah will also be shipped on CentOS, OpenSUSE, RHEL, 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:

The buildah build command now includes a --env option to complement its --unsetenv option.
The buildah build and buildah config commands now accept --os-version and --os-feature flags for setting the corresponding fields in an image’s configuration.
Custom build outputs are now allowed (#3789) and the type and destination can be selected.

This release comprises changes made for v1.25.1 and the main branch and will be included in Podman v4.1.1.

Release Changes

Changes for v1.26.0

Changes were made to the copy algorithm of the build command to prevent concurrent read/write actions on the internal maps.
The buildah build command now includes a --env option to complement its --unsetenv option. See the buildah-build.1.md man page for details.
The default value of the io.buildah.version label can now be overridden at the buildah build command line using the --label option. See the buildah-build.1.md man page for details.
The buildah build and buildah config commands now accept --os-version and --os-feature flags for setting the corresponding fields in an image’s configuration. See the buildah-build.1.md and buildah-config.1.md mang pages for details.
The TARGETPLATFORM variable in the build process is now set correctly when one or more --platform options are specified.
When the --layers option was used, build did not always handle aliases as it should (#3939). This has been corrected.
Custom build outputs are now allowed (#3789) and the type and destination can be selected. See the --output option on the buildah-build.1.md man page for more information.
An error that at times did not allow for a file to be written to a directory during the build process has been corrected.
Error messages now use consistent lowercase ‘invalid’ in returned error messages.
The hostname within the container is now set to the server’s hostname rather than “localhost”.
Fixed an error where only an image with a shortname could be pushed (3915).
The network backend is now initialized appropriately before the first pull rather than defaulting to cni more times than it should have.
Changes were made to the mount functionality called when in a rootless environment to mount volumes appropriately.
Buildah now uses the settings in containers.conf for ‘netns’ configuration.
The buildah build command only accepts at most one argument, it errors now when multiple arguments are given instead of ignoring them.
When trying to add a local image to the manifest while also setting the variant or arch, would fail to find the local image and would pull it from the registry (#3511). This has been corrected.
The io.buildah.version labels can now be suppressed (#3826) in the build and commit commands with the --identity-label option. See the buildah-build.1.md and buildah-commit.1.md man pages for details.
Containers created by running “buildah from” and specifying the base image using its full ID, or during a “buildah build”, will be given shorter auto-generated names.
Fixed a hang caused by a timing issue when the oci runtime would fail.
Fixed an error when running in rootless, not all processes were killed that should have been.
Bump back to v1.26.0-dev

Buildah version 1.25.0 Release Announcement

We’re pleased to announce the release of Buildah version 1.25.0, which is now available from GitHub for any Linux distro. We are shipping this release on Fedora 34, and Fedora 35. 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:

A container will now wait up to four minutes, up from 5 seconds, when it is created before it will fail due to network issues.
A --no-hosts option was added to the build and run commands.
A new global option, --cgroup-manager, has been added.

This release comprises changes made for v1.24.1, v1.24.2, and v1.25.0 and will be included in Podman v4.1.

Release Changes

Changes for v1.25.0

A container will now wait up to four minutes, up from 5 seconds, when it is created before it will fail due to network issues.
A fix for CVE-2022-27651 addressed an issue with inheritable capabilities within the container.
The --mount=type=cache option now supports locking the external cache store.
A --no-hosts option was added to the build and run commands. When used, an /etc/host file is not created within the container or container image by default.
Processing was added to the add command to ensure the context directory is an absolute path.
During a build, if the base image has a healthconfig and the child image does not, the healthconfig is inherited from the base image. This emulates the processing that Docker does.
The buildah container images on quay.io now contain cpp.
The subuid/subgid values in buildah container images on quay.io have been increased to 65535.
Proxy variables are now only added to the container image’s history only if they are specified with the ARG command in the Containerfile. This emulates Docker’s behavior.
A new option, --cgroup-manager, has been added that allows the cgroup manager to be overridden. More information on the Buildah(1) man page.
When the --cgroup-manager is set to systemd, the --systemd-cgroup option for the OCI runtime is used, which is understood by both runc and crun.
A build would fail if a RUN command was specified in a Containerfile after a Volume command. This issue has been addressed.
An issue with the run command’s --cap-add=all option not appropriately setting the capabilities has been corrected.
Support has been added for the FROM command in a Containerfile to allow specification of the OS, ARCH, or VARIANT values. See the --platform option on the buildah-build (1) man page for more details.

Overall Miscellaneous Changes

Documentation:
- The source files for the Containerfile and containeringore man pages have moved to the containers/common project.
- The options for commands in the man pages are now sorted alphabetically.
- Removed references to Kubic for CentOS and Ubuntu on the installation guide.
Vendored:

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

The --compression-format and compression-level flags have been added to the push command.
Several options were added to the --mount option for the Containerfile RUN and run commands.
The build --network option now supports custom networks.

This release comprises changes made for v1.24.0 and will be included in Podman v4.0.

Release Changes

Changes for v1.24.0

Label modification during a build now mimics Docker behavior.
Handle zstd compression when unmarshalling a layer.
A bug was fixed in the build that, under particular circumstances, could cause the build to stall.
The --compression-format and compression-level flags have been added to the push command.
Added the –all-platforms option to “buildah build”.
Added support for --mount=type=tmpfs to the Containerfile RUN and run commands to allow mounting volatile memory instead of persistent storage.
Added support for persistent caching across builds with –mount=type=cache.
Support for --mount=type=bind to the Containerfile RUN and run commands.
The from= field is now a valid option to pass to the --mount option for run. This allows images to be used as a source.
Add support for host.containers.internal in the /etc/hosts
Report ignorefile location when no content is added during a build, and an ignorefile is present.
Support has been added for overlayfs paths that contain a colon.
Rootless containers users should use additional groups by @rhatdan in #3593
USERS specified in a Containerfile can now become members of a supplementary group as specified in a Containerfile.
NetworkEnabled is now set appropriately when passed with the --network option.
Support was added to allow an environment variable to specify the source of a secret for a build command.
The image history no longer contains ARG values.
The /sys file system is no longer mounted if it is not needed.
An image’s variant field can now be seen via the inspect command or set with the config command.
The build --network option now supports custom networks.
Output for several errors were changed to show the command output for better debugging.
The --unsetenv option was added to the commit and build commands.
The time before closing an ssh connection has been Increased to allow for ssh enough time to close properly.
Multiple filters are now accepted by the images command.
The MediaType in OCI manifests is now set properly.
Rootless buildah commands can now set resource limits on cgroup V2.
The --memory-swap option for the build command can be set to -1 to allow unlimited memory swap.
Callers of the build command, such as Podman, can now replace the ContainerPrefix with a value of their choosing.
Fix default CNI paths so that their value is no longer hardcoded but pulled from the containers.conf file.
A number of changes were made to the Cobra CLI calls to make things more consistent for developers and end users.
Fixed the --platform option for the build command so it appropriately uses the value passed into it.
A fix was added to allow the runtime to be searched using a fully qualified path.
Added support to specify non-volatile upperdir and workdir for overlay volumes with the Containerfile RUN and run commands.
The pull commands are now: --pull, --pull=true, --pull=false, --pull=never, and --pull=always. Older commands such as --pull-always and --pull-never are still functional but are no longer documented.

Overall Miscellaneous Changes

Buildah version 1.22.0 Release Announcement

We’re pleased to announce the release of Buildah version 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.

Release Changes

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

Overall Miscellaneous Changes

Documentation:
- Remove specific kernel version number requirement from install.md.
- In buildah bud: –ignore-file requires a parameter.
- In push/pull man pages: clarify supported transports.
- Fix documentation of the –format option of buildah push.
- Clarify rmi removes dangling parents in the rmi man page.
- Fix links to containers/image master branch to the new main branch.
Vendored:

- Adjust conformance-test error-message regex to account for a change in output.
- Make it easier to override the location of the copy helper in some tests.
- Workarounds for the appearance of differing debug messages.
Changes to the build infrastructure:
- Always push updated version-tagged multi-arch container images.
- Made steps generic for the multi-arch container image build process.

Buildah version 1.21.0 Release Announcement

We’re pleased to announce the release of Buildah version 1.21.0, 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:

A --secret option has been added to the bud command, which allows passing secret information (such as a database password) to the Container without it being stored in the final image. See the buildah bud man page for more information.
The buildah manifest rm command has been added and allows the user to remove one or more manifest lists. See the buildah manifest and buildah manifest rm man pages for more information.
The code that did container image handling has been removed from Buildah and replaced with the new libimage package that resides in containers/common. This code is used by a number of projects in the Containers organization and has proven to be more efficient than the older code.

This release comprises changes made for v1.20.0 through v1.21.0.

Release Changes

Changes for v1.21.0

Containerfiles no longer fail during CPP processing if a comment is contained within the file.
The --default-mounts-file option for the buildah bud command now works correctly.
The logrus messages for Info, Warning, and Debug are now being written to stderr when using the buildah bud command.
The check for a bad image name now happens much earlier in the build process rather than at the end.
When podman build pulled an image, it would use the --pull-never policy, using only the locally available image. This has been corrected, and the image is now pulled from the registry if it is available.
Fixed a couple of race conditions that were causing containers to fail just before they exited.
The ownership of a lower directory is preserved when doing an overlay mount, similar to the way that bind mounts work.
The handling of images with signatures could fail under certain circumstances, this has been corrected.
Errors emitting from the runtime are now more clearly labeled.
The logic involving built-in volumes has been reworked to better handle non-overlayfs mounts.
Changes were made to work better with the VFS driver.
A --secret option has been added to the bud command, which allows passing secret information (such as a database password) to the Container without it being stored in the final image. See the buildah bud man page for more information.
The buildah manifest rm command has been added and allows the user to remove one or more manifest lists. See the buildah manifest and buildah manifest rm man pages for more information.
The non functioning and unsupported buildah bud --loglevel option has been removed.
The code that did container image handling has been removed from Buildah and replaced with the new libimage package that resides in containers/common. This code is used by a number of projects in the Containers organization and has proven to be more efficient than the older code.
The buildah bud command handled multiple tags but did not report them to the user. If there are multiple tags, buildah bud now reports that.
Logged debugging and error messages will once again include a count of seconds elapsed since buildah was started.

Overall Miscellaneous Changes

Documentation:
- Documented the location of the auth.json file if XDG_RUNTIME_DIR is not set.
- Updated the steps for runc users on CentOS in the install guide.
- Removed several older distro from the install guide.
- Minor fixes to Buildah as a library tutorial documentation.
Vendored:
- Vendor in containers/common v0.38.4

We’re pleased to announce the release of Buildah version 1.20.0, 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 these notable enhancements:

A number of packages and dead code have been removed from Buildah to shrink the size of its executable.
- This included moving the internal structure definitions in Buildah to the ‘define’ subdirectory, so tools like Podman that vendor in Buildah could be streamlined.
Buildah’s copy processing has been changed to speed up the processing and better support rootless users.
Multi-arch container images are now built automatically and are available for Buildah on quay.io
The buildah add and buildah copy commands have added the --chmod option to set the destination permissions.
A few issues with the recently added buildah manifest command have been addressed.
A number of other bug fixes have been completed.

This release comprises changes made for v1.19.0 through v1.20.0.

Release Changes

Changes for v1.20.0

Multi-arch Buildah container images are now provided on quay.io.
Use a faster way to check the container image for a version tag existence during multi-arch build of Buildah images on quay.io.
Look for a Containerfile file if the user specifies a directory with the --file/-f option in the bud command.
Added a number of changes to Bulidah’s copy logic to gain speed improvements and allow more robust functionality for rootless users.
Changes were made to allow the different kinds of pull to work with Podman’s REST API.
An image would not be pulled when pulling a specific architecture and the same image with a different architecture was already present.
Permissions set on the destination directory of a container using overlayfs were not always set. This has been corrected.
A number of unused packages were removed to shrink the size of the Buildah executable.
Added a colon to the buildah images <image_name> error message to differentiate the error message from the error-inducing image name.
The add/copy man pages now have --chmod examples.
The buildah login and buildah logout commands entered user namespace and did not need to. This has been corrected.
Bash completions for the chmod and chown options have been corrected.
If an image was built with an older version of Buildah, the Buildah version label in the image is now being updated when a newer version of Buildah changes it.
The values of isolation strings: oci, chroot, and rootless, are now being handled appropriately.
Build stages with no instructions are no longer reaped.
The name of the base image is now stored in the comment of the image’s first layer.
The overlay file system has a new “volatile” mount option which reduces I/O by ignoring fsync and syncfs requests. This has been enabled for Buildah containers.
A number of options in the buildah config command now support the - value (single dash), which removes all values in the configuration for that option type. Examples are --label, --port, and more. See the buildah config man page for details.
When building an image with the same build args, the cache was not used Issue 2992. This has been corrected.
The buildah add and buildah copy commands have added the --chmod option to set the destination permissions.
The --iidfile option now prefixes the imageId with a hash character compatible with Docker.
A few issues with the recently added buildah manifest command have been addressed.
Several changes were made to better handle the --build-arg option in the buildah bud command.
Local container images can now be looked up by digest.
The default OCI Runtime is now determined by the value in the containers.conf file.
If the destination of a volume mount does not exist, Buildah now creates the destination directory in the container rather than throwing an error.

Overall Miscellaneous Changes

Documentation:
- Fixed rootful typo in docs.
- Added documentation and testing for .containerignore.
- Clarified userns options in man pages.
- Remove the duplicate arch and os from the from man page.

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

This will also be shipped on CentOS, openSUSE and Ubuntu in the near future. 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: A number of changes made to the bud command in order to speed up build processing, a static build of Buidah is now available via nix, environment variables can now be set in containers.conf and the --jobs option has been added to the bud command.

A number of changes to the internal processing of the bud command have been made to speed up the processing of that command. Some nice gains have been made and work continues on further improvements.
The Nix package manager can now be run to create a static build of Buildah.
Environment variables that will be common to all your container images can now be set in the containers.conf file. See the containers.conf man page for more details.
The --jobs option in the bud command now allows for multiple jobs to be run in parallel. See the bud man page for more details.

This release comprises changes made for v1.15.1 through v1.15.2 and v1.16.0.

Release Changes

Changes for v1.16.0

When a new layer is created in the build process, the time of the layer is no longer set to the current time if a timestamp is not provided.
The retry delay option values for retrying that were sent to the commit, pull and push commands are now honored.
The handling of seccomp is now done in the containers/common project.
The --timestamp option has been added to the bud and commit commands to allow the ‘create’ timestamp to be set to seconds since epoch, replacing the --omit-timestamp option. See the respective man pages for more information.
The --quiet option should be more quiet.
Fix ownership of content copied using COPY --from, prior ownership information on files was being dropped.
Error handling was improved in the run command and a few messages were clarified.
A copier package is now used internally to rework the handling of caches during ADD and COPY operations.
When doing a COPY of an archive file, the destination file name was incorrectly being blanked out; this has been corrected.
The retry functions have been replaced by functions from the common/pkg/retry package.
A number of timestamp comparisons were being done with == and they have been converted to use time.Time.Equal() which is more accurate.
Fixed errors found in a Coverity scan.
Namespace handling options in the bud, from and run commands have been changed to match the same options in Podman. In addition the --network option for bud now accepts the same values that the corresponding Podman command does.
A dependency on the xz package has been added to Buildah images that are built for quay.io.
Storage was not always shutdown as it should have been on error, which could lead to a leaked mount point. This has been corrected.
The COPY --from command now works when an argument is given to it.
The version of Buildah used to build an image is now embedded in the BuilderIdentityAnnotation within the image.
The /etc/host and /etc/resolv.conf files are no longer bound if network is not present in the container.
An unnecessary call to the function NewImage() has been removed from the build processing.
When processing multiple archives during a .dockerignore process, the processing would stop at the end of the first archive. Now all archives are processed as they should be.
Fixed & added notes regarding problematic language in the codebase that were not inclusive.
Added a dependency on github.com/stretchr/testify/require.
The build processing now waits for stages that might not have even started yet instead of trying to continue and then failing.
Mounts under /sys were not always accessible to rootless users. This has been corrected.
Environment variables can now be pre-declared in the containers.conf(5) file.
The right stage’s image is now returned as the “final” image.
When build arguments and environment variables have duplicate names, the values are now deduplicated. Build arguments override Default arguments and Environment variables set during the build process override both of those.
Made changes based on the project containers/libpod renaming itself to containers/podman.
A Containerfile to build the stable buildah image using Centos7 was added.
A race condition has been created that would cause a failure if the container would exit before the runtime sent a signal.
Made changes to how Buildah handled the /sys/fs/selinux mountpoint so that it would be available to Podman.
The files needed to run VFS in the Buildah container images were added.
The value “readonly” can now be used as an alias to “ro” in mount options.
The OS X specific --consistency mount option is now ignored.
When doing builds where one stage requires the result of an earlier stage, Buildah now waits for that first stage to complete before the dependent stage starts.
Resolved a possible race in map handling during build stage processing.
The Dockerfiles that build the Buildah container images now use a containers.conf file.
The --jobs option in the bud command now allows for multiple jobs to be run in parallel.
Bump to v1.17.0-dev

We are shipping this release on Fedora, RHEL 8, CentOS, openSUSE and Ubuntu in the near future. Also container images will be available at https://quay.io/repository/buildah/stable.

The Buildah project has continued to grow over the past several weeks, welcoming several new contributors to the mix. This release features a new containers.conf file, added options for the bud, commit, push and pull commands, and many bug fixes. Notable enhancements:

Containers.conf support. Containers.conf is a way to modify the default ways containers run on the system. The /usr/share/containers/containers.conf and /etc/containers/containers.conf files can now be used by Buildah to attain configuration options. In the near future Podman, Skopeo and other projects in the Containers repository will make use of these files too.
A number of performance improvements were made to the bud command, especially so when a .dockerignore file was in use.
The bud command now accepts --os and --arch as options.
A --sign-by option has been added to the bud, commit and push commands.
A --remove-signatures option has been added to the pull and/push commands.

This release comprises changes made for v1.13.1, v1.13.2 and v1.14.0.

Environment variables were not always resolved appropriately in COPY commands in Dockerfiles, this has been corrected.
A --sign-by option has been added to the bud, commit and push commands. See the man pages for details.
A --remove-signatures option has been added to the pull andpush commands. See the man pages for details.
Support was added for /etc/containers/containers.conf when running as root, and /usr/share/containers/containers.conf when running as a rootless user.
Added codespell support to the builds to catch spelling errors.
A number of internal changes were made to tar file handling in the build process to close files at an appropriate time and to not digest files that the process would otherwise ignore.
A number of changes were made to speed up the bud command when .dockerignore was in use.
Set the HOME environment variable to /root on chroot-isolation by default.
When the buildah bud --volume command runs, it now runs in TMPDIR rather than in the source directory.
The format of images names returned from the from command are now more consistent.
The bud command has been made quiet again when the --quiet option is used.

Buildah version 1.13.0 Release Announcement

We’re pleased to announce the release of Buildah version 1.13.0 which is now available from GitHub for any Linux distro. We are shipping this release on Fedora, RHEL 8, RHEL 7, CentOS, openSUSE and Ubuntu in the near future. Also container images will be available at https://quay.io/repository/buildah/stable.

The Buildah project has continued to grow over the past several weeks, welcoming several new contributors to the mix. This release had a quick release cadence due to a few critical issues with volume handling. Notable enhancements:

Changes to unmount volumes cleanly and to handle full volume specifications in the bud command.
$TMPDIR, which defaults to /var/tmp is now used when pulling and pushing images.
Further support added to enable FIPS-Mode.

This release comprises changes made for v1.13.0.

Release Changes

Changes for v1.13.0

The version of containers/storage vendored in this release has a fix to handle the situation when a volume was ‘unmounted’ by the user, but due to namespace handling, the counter tracking the number of mounts the volume had was not decremented as it should have been.
Fixed option handling for volumes in build. If a volume specification had a comma within it i.e. myvol:/myvol:rw,Z, the CLI parsed the ,Z incorrectly and errored.
Reworked the overlay pkg so it could be more easily shared with libpod.
Fixed buildahimage builds for the Buildah images on quay.io. The shadows-utils package is now installed on those images and a default user build has been added to force the generation of the /etc/subuid and /etc/subgid files. This should allow for the building of a container in that image by a non-root user.
Add support for FIPS-Mode backends to the project.
The TMPDIR used for pushing and pulling images is now set to $TMPDIR. By default this points to the /var/tmp directory. This should correct the issue of running out of space when doing a push or pull.

Overall Miscellaneous Changes

Vendored:
- Bump github.com/containers/storage to v1.15.5
- Bump github.com/containers/image/v5 from 5.0.0 to 5.1.0
- Bump github.com/containers/common from 0.0.3 to 0.0.5
Tests:
- Develop a safer test for pull –all-tags
- BATS major cleanup: blobcache.bats: refactor
- BATS major cleanup: Added a number of missing ‘run_buildah’ commands, changed the log-level in the tests, and a number of small cleanups throughout.
Plus a number of smaller fixes.
