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. docs

Notable Changes

• 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
• 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) #2758 #2848 #2871 #2814
• Bake: Make FS entitlements error by default. To disable it, you can set BUILDX_BAKE_ENTITLEMENTS_FS=0 #2875
• Bake: Infer git auth token from remote files to build request #2905
• Bake: Add support for --list flag to list targets and variables #2900 #2907
• Bake: Update lookup order for default definition files to load the files with "override" suffix later #2886
• Bake: Fix entitlements check for default SSH socket #2898
• Bake: Fix named context from target platform matching #2877
• Bake: Fix missing default target in group's default targets #2863
• Validate BuildKit configuration before creating a builder #2864
• Compose compatibility has been updated to v2.4.7 #2893 #2857 #2829
• Fix missing last progress from loading layers #2876
• Fix missing documentation for quiet progress mode #2899
