0.10.0
2023-01-10Note
Buildx v0.10 enables support for a minimal SLSA Provenance attestation, which requires support for OCI-compliant multi-platform images. This may introduce issues with registry and runtime support (e.g. Google Cloud Run and AWS Lambda). 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#1412 docker/buildx#1475--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 settingBUILDX_GIT_LABELS=1
. docker/buildx#1462, docker/buildx#1297, docker/buildx#1341, docker/buildx#1468, docker/buildx#1477 - Named contexts with
--build-context
now supportoci-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#1456 - Bake now supports resource interpolation where you can reuse the values from other target definitions. docker/buildx#1434
- 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 builds support in BuildKit v0.11.0+. docker/buildx#1482 - Buildx now remembers the last activity for a builder for better organization of builder instances. docker/buildx#1439
- 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#1449
- The
buildx imagetools inspect
command now supports showing SBOM and Provenance data. docker/buildx#1444, docker/buildx#1498 - Increase performance of
ls
command and inspect flows. docker/buildx#1430, docker/buildx#1454, docker/buildx#1455, docker/buildx#1345 - Adding extra hosts with
Docker driver now supports
Docker-specific
host-gateway
special value. docker/buildx#1446 - OCI exporter now supports
tar=false
option for exporting OCI format directly in a directory. docker/buildx#1420

0.9.0
2022-08-17New

- Build commands now support new the build context type
oci-layout://
for loading build context from local OCI layout directories. Note that this feature depends on an unreleased BuildKit feature and builder instance frommoby/buildkit:master
needs to be used until BuildKit v0.11 is released. docker/buildx#1173 - 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

. This feature is experimental for gathering early feedback and requires enablingBUILDX_EXPERIMENTAL=1
environment variable. We plan to update/extend this feature in the future without keeping backward compatibility. docker/buildx#1100, docker/buildx#1272 - 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 enablingBUILDX_EXPERIMENTAL=1
environment variable. We plan to update/extend this feature in the future without enabling backward compatibility. docker/buildx#1168, docker/buildx#1257, docker/buildx#1259 - Buildx now understands environment variable
BUILDKIT_COLORS
andNO_COLOR
to customize/disable the colors of interactive build progressbar. docker/buildx#1230, docker/buildx#1226 buildx ls
command now shows the current BuildKit version of each builder instance. docker/buildx#998- The
bake
command now loads.env
file automatically when building Compose files for compatibility. docker/buildx#1261 - Bake now supports Compose files with
cache_to
definition. docker/buildx#1155 - Bake now supports new builtin function
