Welcome to the 0.8.0-rc1 release of buildx!
*This is a pre-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](https://github.com/docker/buildx/blob/v0.8.0-rc1/docs/reference/buildx_build.md#build-context)
- 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 [Documentation](https://github.com/docker/buildx/blob/v0.8.0-rc1/docs/reference/buildx_bake.md#defining-additional-build-contexts-and-linking-targets)
- `imagetools inspect` now accepts `--format` flag allowing access to config and buildinfo for specific images. 854
- 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
- Show last access time in `du` command 867
- Target names in Bake are now restricted to not use special characters 929
- Fix some nested inheritance cases in Bake 914
- Fix printing default group on Bake files 884
