buildx

Welcome to the 0.8.0 release of buildx!

Please try out the release binaries and report any issues at
https://github.com/docker/buildx/issues.

Notable Changes

• Build command now accepts --build-context flag to define additional named build contextes for your builds. For example, these can be used expose additional local directories to your build or pin an image to a specific digest. This feature requires using Dockerfile 1.4+ frontend. #904 Documentation

• Bake definitions now support defining dependencies between targets and using the result of one target in another build. This feature requires using Dockerfile 1.4+ frontend. #928 #965 #963 #962 #981 Documentation

• imagetools inspect now accepts --format flag allowing access to config and buildinfo for specific images. #854 #972

• New flag --no-cache-filter allows configuring build so it ignores cache only for specified Dockerfile stages #860

• --metadata-file output now supports embedded structure types. These are used for example for returning build info and image descriptors in BuildKit v0.10. #946

• Builds can now show a summary of warnings set by the building frontend #892

• buildx rm now accepts new flag --all-inactive for removing all builders that are not currently running #885

• Proxy config is now read from Docker configuration file and sent with build requests for backward compatibility #959

• Fix environment file handling in Compose files #905

• New build-arg BUILDKIT_INLINE_BUILDINFO_ATTRS allows opting-in to embedding building attributes to resulting image #908

• Support host networking in Compose #863 #880

• Bake files can now be read from stdin with -f - #864

• New flag --keep-buildkitd allows keeping BuildKit daemon running when removing a builder #852

• --iidfile now always writes the image config digest independently from the driver being used. Use --metadata-file to access image manifest digest. #980

• Show last access time in du command #867

• Target names in Bake are now restricted to not use special characters #929

• Image manifest digest can be read from metadata when pushed with Docker driver #989

• Fix possible double output logs when multiple bake targets run same build steps #977

• Fix possible errors on multi-node builder building multiple targets with mixed platform #985

• Fix some nested inheritance cases in Bake #914

• Fix printing default group on Bake files #884

• Fix UsernsMode when using rootless container #887
