0.10.0

Note

Buildx v0.10 enables support for a minimal SLSA Provenanceopen_in_new attestation, which requires support for OCI-compliantopen_in_new multi-platform images. This may introduce issues with registry and runtime support (e.g. Google Cloud Run and AWS Lambdaopen_in_new). You can optionally disable the default provenance attestation functionality using --provenance=false.

New

• The buildx build command supports new --attest flag, along with shorthands --sbom and --provenance, for adding attestations for your current build. docker/buildx#1412open_in_new docker/buildx#1475open_in_new
  • --attest type=sbom or --sbom=true adds SBOM attestations.
  • --attest type=provenance or --provenance=true adds SLSA provenance attestation.
  • When creating OCI images, a minimal provenance attestation is included with the image by default.
• When building with BuildKit that supports provenance attestations Buildx will automatically share the version control information of your build context, so it can be shown in provenance for later debugging. Previously this only happened when building from a Git URL directly. To opt-out of this behavior you can set BUILDX_GIT_INFO=0. Optionally you can also automatically define labels with VCS info by setting BUILDX_GIT_LABELS=1. docker/buildx#1462open_in_new, docker/buildx#1297open_in_new, docker/buildx#1341open_in_new, docker/buildx#1468open_in_new, docker/buildx#1477open_in_new
• Named contexts with --build-context now support oci-layout:// protocol for initializing the context with a value of a local OCI layout directory. E.g. --build-context stagename=oci-layout://path/to/dir. This feature requires BuildKit v0.11.0+ and Dockerfile 1.5.0+. docker/buildx#1456open_in_new
• Bake now supports resource interpolation where you can reuse the values from other target definitions. docker/buildx#1434open_in_new
• Buildx will now automatically forward SOURCE_DATE_EPOCH environment variable if it is defined in your environment. This feature is meant to be used with updated reproducible buildsopen_in_new support in BuildKit v0.11.0+. docker/buildx#1482open_in_new
• Buildx now remembers the last activity for a builder for better organization of builder instances. docker/buildx#1439open_in_new
• Bake definition now supports null values for variables and labels for build arguments and labels to use the defaults set in the Dockerfile. docker/buildx#1449open_in_new
• The buildx imagetools inspect command now supports showing SBOM and Provenance data. docker/buildx#1444open_in_new, docker/buildx#1498open_in_new
• Increase performance of ls command and inspect flows. docker/buildx#1430open_in_new, docker/buildx#1454open_in_new, docker/buildx#1455open_in_new, docker/buildx#1345open_in_new
• Adding extra hosts with Docker driver now supports Docker-specific host-gateway special value. docker/buildx#1446open_in_new
• OCI exporter now supports tar=false option for exporting OCI format directly in a directory. docker/buildx#1420open_in_new

Note that this feature depends on an unreleased BuildKit feature and builder instance from moby/buildkit:master needs to be used until BuildKit v0.11 is released. docker/buildx#1173open_in_new
• You can now use the new --print flag to run helper functions supported by the BuildKit frontend performing the build and print their results. You can use this feature in Dockerfile to show the build arguments and secrets that the current build supports with --print=outline and list all available Dockerfile stages with --print=targets. This feature is experimental for gathering early feedback and requires enabling BUILDX_EXPERIMENTAL=1 environment variable. We plan to update/extend this feature in the future without keeping backward compatibility. docker/buildx#1100open_in_new, docker/buildx#1272open_in_new
• You can now use the new --invoke flag to launch interactive containers from build results for an interactive debugging cycle. You can reload these containers with code changes or restore them to an initial state from the special monitor mode. This feature is experimental for gathering early feedback and requires enabling BUILDX_EXPERIMENTAL=1 environment variable. We plan to update/extend this feature in the future without enabling backward compatibility. docker/buildx#1168open_in_new, docker/buildx#1257open_in_new, docker/buildx#1259open_in_new

• You can now set the default builder config that is used when creating builder instances without passing custom --config value. docker/buildx#1111open_in_new
