Note

This version of buildx enables filesystem entitlement checks for buildx bake command by default. If your Bake definition needs to read or write files outside your current working directory, you need to allow access to these paths with --allow fs=<path|*>. On the terminal, you can also interactively approve these paths with the provided prompt. Optionally, you can disable these checks by setting BUILDX_BAKE_ENTITLEMENTS_FS=0. This validation produced a warning in Buildx v0.19.0+, but starting from current release it produces an error. For more information, see the reference documentation.

New

• New buildx history command has been added that allows working with build records of completed and running builds. You can use these commands to list, inspect, remove your builds, replay the logs of already completed builds, and quickly open your builds in Docker Desktop Build UI for further debugging. This is an early version of this command and we expect to add more features in the future releases. #2891, #2925

Enhancements

• Bake: Definition now supports new object notation for the fields that previously required CSV strings as inputs (attest, output, cache-from, cache-to, secret, ssh). docker/buildx#2758, docker/buildx#2848, docker/buildx#2871, docker/buildx#2814
• Bake: Filesystem entitlements now error by default. To disable this behavior, you can set BUILDX_BAKE_ENTITLEMENTS_FS=0. docker/buildx#2875
• Bake: Infer Git authentication token from remote files to build request. docker/buildx#2905
• Bake: Add support for --list flag to list targets and variables. docker/buildx#2900, docker/buildx#2907
• Bake: Update lookup order for default definition files to load the files with "override" suffix later. docker/buildx#2886

Bug fixes

• Bake: Fix entitlements check for default SSH socket. docker/buildx#2898
• Bake: Fix missing default target in group's default targets. docker/buildx#2863

0.19.1

The full release notes for this release are available on GitHub.

Bug fixes

• Reverted the change in v0.19.0 that added new object notation for the fields that previously required CSV strings in Bake definition. This enhancement was reverted because of backwards incompatibility issues were discovered in some edge cases. This feature has now been postponed to the v0.20.0 release. docker/buildx#2824

0.19.0

The full release notes for this release are available on GitHub.

New

• Bake now requires you to allow filesystem entitlements when your build needs to read or write files outside of your current working directory. docker/buildx#2796, docker/buildx#2812.

  To allow filesystem entitlements, use the --allow fs.read=<path> flag for the docker buildx bake command.

  This feature currently only reports a warning when using a local Bake definition, but will start to produce an error starting from the v0.20 release. To enable the error in the current release, you can set BUILDX_BAKE_ENTITLEMENTS_FS=1.

Enhancements
