Notable Changes

FileOp

LLB supports new operation FileOp allowing built-in file operations during build like copying files, creating new files or directories and removing files. Previously ADD/COPY commands used a helper image that ran a custom binary inside a container, now these commands use FileOp directly. This allows better performance and use of these commands in air-gapped environments without preloading the helper image, as well as fixing issues reported with the helper image implementation.

#809

Security entitlements

BuildKit now supports modes for granting builds permissions to execute processes with privileged capabilities. Certain options for running processes with LLB will require users to grant a capability before their build can run.

This enables specific builds to run processes that require system capabilities without compromising on the security of the default builds.

Currently two entitlements are supported:

network.host - Runs a specific process in the host network namespace.
security.insecure - Runs a process with all system capabilities enabled and security modules (eg. seccomp) disabled. Similar to docker run --privileged.

The entitlements need to be enabled both in the daemon configuration file and passed with a build request using --allow to take effect.

#570

New connection helpers for buildctl

Buildctl now has support for connecting to BuildKit daemon running in a Docker container or Kubernetes pod by using docker-container://<name> or kube-pod://<name> as BUILDKIT_HOST value.

#904
#951

Tar exporter

Build output can now be exported to the client as a tarball. Similar to the local exporter but allows preserving the file owner values.

buildctl build -o type=tar,dest=foo.tar ...
buildctl build -o type=tar ... > foo.tar

#907

New progress output formatting

Progress output has been improved. The TTY output now shows the last logs for currently running processes directly in the interactive output. Plain progress has been also updated for better readability.

#916
#919

dockerfile/1.1.0

ADD/COPY commands now support implementation based on llb.FileOp and do not require helper image if builtin file operations support is available. #809

To find the files ignored from the build context Dockerfile frontend will first look for a file <path/to/Dockerfile>.dockerignore and if it is not found .dockerignore file will be looked up from the root of the build context. This allows projects with multiple Dockerfiles to use different .dockerignore definitions. #901

--chown flag for COPY command now supports variable expansion. #926

Notable Changes

securityContext is no longer needed for running BuildKit on Kubernetes (#768)

moby/buildkit:v0.4.0-rootless does not require securityContext.procMount (or securityContext.privileged) to be configured when launched with --oci-worker-no-process-sandbox, which disables isolating PID namespaces across buildkitd and build containers.

To run moby/buildkit:v0.4.0-rootless using docker run, you still need to specify --security-opt seccomp=unconfined --security-opt apparmor=unconfined but you no longer need to specify --privileged.

See also https://github.com/moby/buildkit/blob/v0.4.0/docs/rootless.md

Cache can be now embedded into an image and can be pushed together (#777)

Prior to v0.4.0, cache and image needed to be pushed separately: buildctl build --output type=image,name=example.com/foo/bar,push=true --export-cache type=registry,ref=example.com/foo/bar:cache --import-cache type=registry,ref=example.com/foo/bar:cache

Now cache be embedded into an image by specifying --export-cache type=inline and on importing you can just point the --import-cache type=registry,ref=example.com/foo/bar directly to your end image.

Cache can be now exported to a local filesystem (#615 , #807)

Cache can be now exported to a local filesystem (e.g. Travis CI cache directories) using --export-cache type=local,dest=/path/to/dir and can be imported using --import-cache type=local,src=/path/to/dir.

New buildctl CLI (#807)

CLI options for frontend options, exporters and cache export and import have been normalized to csv style for less verbosity and (future) support for multiple exporters and cache sources.

Frontend options:

Old:

--frontend-opt foo=bar --frontend-opt bar=baz

New:

--opt foo=bar,bar=baz --opt baz=bay

Exporters:

Old:

--exporter image --exporter-opt name=foo --exporter-opt push=true
--exporter local --exporter-opt output=out

New:

--output type=image,name=foo,push=true
--output type=local,dest=out

Cache:

Old:

--export-cache foo --export-cache-opt mode=max
--import-cache foo

New:

--export-cache type=registry,ref=foo,mode=max
--export-cache type=inline
--export-cache type=local,dest=/path/to/dir
--import-cache type=registry,ref=foo
--import-cache type=local,src=/path/to/dir

Legacy syntax is still supported but has been deprecated.
