Notable Changes

• Imagetools create and inspect commands now support OCI layout paths as source and destination that can be used together with registry references #3721
• Bake command supports new builtin functions formattimestamp and unixtimestampparse for better handling of time values #3286
• DAP debugger support is now generally available without the need for the experimental features flag #3736
• policy eval command now supports --platform flag to specify the platform for evaluated image sources #3738

• policy eval flag --filename has been renamed to --file for consistency with other commands. The previous flag is deprecated. #3738

Notable Changes

• Imagetools now supports --metadata-file flag to capture properties like descriptor/digest values for the new image. #3638
• Imagetools auth libraries have now been combined with the ones used in build commands, enabling previously missing support for scoped credentials and automatic fallbacks for Docker Hardened Image registries. #3627
• Many commands now support --timeout flag to configure the timeout for waiting for responses from remote builders. #3665
• Rego Policy now supports validating builds from remote sources (Git, HTTP) #3661
• Rego Policies now include new builtins for validating signed Sigstore bundle attestations of HTTP source artifacts. Attestations can also be automatically fetched from Github API #3657
• Rego policies can now use input.image.provenance to write rules validating specific provenance attestation fields. Materials of provenance can be accessed as policy secondary inputs. Requires BuildKit v0.28+ #3652 #3662
• Builds failing due to policy violations now have better error messages with the failing step clearly marked and the last policy logs shown with the error. #3656
• Fix possible passing of incorrect Git auth token for Bake builds when multiple remotes with different hosts exist. #3648
• Fixed policy filesystem reference lifecycle handling to avoid stale policy filesystem state during builds. #3674
• Normalized default policy filename resolution from environment configuration for more consistent behavior. #3675
• Named contexts used in different projects now get unique "shared keys" (previously based on context name) to avoid overwriting destinations of other projects, with reduced performance. This feature requires Dockerfile 1.22+ #3618
• Fix local subdir named context copied with wrong parent directory for remote Bake builds #3678
• Bake builds now capture the original URL information of named contexts sent as inputs in request metadata #3682 #3462
• Additional metrics associated with DAP debugger have been added #3633
• DAP file explorer now gets a more accurate state of the file system via updated BuildKit API #3450
• DAP file explorer source names have been improved #3631
• Improve the output of -q used with --call #3655

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

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
  • 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.
• 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
• 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
