Bazel Buildfarm

This repository will host a Bazel remote caching and execution system.

This project is just getting started.

Read the meeting notes. Get involved by joining the discussion on the dedicated mailing list.

Usage

In general do not execute server binaries with bazel run, since bazel does not support running multiple targets.

All commandline options override corresponding config settings.

Bazel BuildFarmServer

Run via

bazel build //src/main/java/build/buildfarm:buildfarm-server && \
bazel-bin/src/main/java/build/buildfarm/buildfarm-server <configfile> [-p PORT] [--port PORT]

• configfile has to be in (undocumented) Protocol Buffer text format.

  For format details see here. Protocol Buffer structure at src/main/protobuf/build/buildfarm/v1test/buildfarm.proto

• PORT to expose service endpoints on

Bazel BuildFarmWorker

Run via

bazel build //src/main/java/build/buildfarm:buildfarm-worker && \
bazel-bin/src/main/java/build/buildfarm/buildfarm-worker <configfile> [--root ROOT] [--cas_cache_directory CAS_CACHE_DIRECTORY]

• configfile has to be in (undocumented) Protocol Buffer text format.

  For format details see here. Protocol Buffer structure at src/main/protobuf/build/buildfarm/v1test/buildfarm.proto

• ROOT base directory path for all work being performed.

• CAS_CACHE_DIRECTORY is (absolute or relative) directory path to cached files from CAS.

Developer Information

Third-party Dependencies

Most third-party dependencies (e.g. protobuf, gRPC, ...) are managed automatically via bazel-deps. After changing the dependencies.yaml file, just run this to regenerate the 3rdparty folder:

git clone https://github.com/johnynek/bazel-deps.git ../bazel-deps2
cd ../bazel-deps
bazel build //src/scala/com/github/johnynek/bazel_deps:parseproject_deploy.jar
cd ../bazel-buildfarm
../bazel-deps/gen_maven_deps.sh generate -r `pwd` -s 3rdparty/workspace.bzl -d dependencies.yaml

Things that aren't supported by bazel-deps are being imported as manually managed remote repos via the WORKSPACE file.
