Notable Changes

• This is a first version of Buildx with signed artifacts built using Docker Github Builder
• This release comes with new experimental support for source policy enforcement during builds using policies written in Rego language. There are some limitations in this release, for example, only builds from the local build context currently load policies. #3593 #3539 #3592 #3611 docs
  • Matching policy for Dockerfile is loaded automatically if one exists, e.g., Dockerfile.rego or app.Dockerfile.rego.
  • Additional policy configuration can be provided using new build --policy flag.
  • Bake also supports automatic policy loading and a new policy key in the target configuration.
  • New buildx policy command includes subcommands eval and test to help you write and test your policies.
• Bake command has a new --var flag to set variable values from the command line instead of setting environment variables. #3610
• When creating images in Docker image store, they no longer unpack if export was initialized with --push or -o type=registry #3519
• Add semvercmp helper function to Bake stdlib for easier version comparisons #3577
• Retry transient TLS errors when talking to Kubernetes nodes #3493
• Allow disabling Bake env lookups so bake can ignore host environment variables #3595
• Add possibility to load Docker configs scoped to specific repos/scopes for finer credential control #3562
• When building images from Docker Hardened Images (dhi.io) and Docker Scout registries, authentication will now automatically fall back to Docker Hub credentials if no specific credentials are found. #3612
• Fix the --debug flag issues in standalone mode #3554
• Fix handling @ characters inside OCI layout paths passed to build #3583
• Surface policy controls --policy, policy eval, custom builtins/Regos/gitsign checks so builds can enforce policies #3593 #3549
• Prevent DAP breakpoint overlaps from triggering false positives #3534
• Fix mount input names in DAP run mounts #3579
• Fix DAP breakpoint reason reporting #3581
