Bazel

The gcr.io/cloud-builders/bazel image is maintained by the Cloud Build team, but it may not support the most recent features or versions of Bazel. We also do not provide historical pinned versions of bazel.

The Bazel team provides a bazel image that supports multiple tagged versions at http://gcr.io/cloud-marketplace-containers/google/bazel.

To migrate to the Bazel team's official Bazel image, make the following changes to your cloudbuild.yaml:

- name: 'gcr.io/cloud-builders/bazel'
+ name: 'gcr.io/cloud-marketplace-containers/google/bazel'
+ entrypoint: 'bazel'

Example Usage

steps:
- name: 'gcr.io/cloud-marketplace-containers/google/bazel'
  entrypoint: 'bazel'
  args: ['build', '//java/com/company/service:server']

---

Usage Details

This is a tool builder to simply invoke bazel commands.

Arguments passed to this builder will be passed to bazel directly.

The latest available version of bazel is used.

Examples

The following examples demonstrate build request that use this builder:

Build a target

This cloudbuild.yaml simply builds a target. It might be a binary, a library, a test target, or any other buildable target.

steps:
- name: gcr.io/cloud-builders/bazel
  args: ['build', '//java/com/company/service:server']

Build and push a container image

If the rule is a docker_build target, then you can bazel run the target to build a Docker image and load it into the Docker daemon. You can then tag the resulting image so it can be pushed to the Container Registry.

path/to/some/BUILD file:

docker_build(
  name = "docker_target",
  base = "@docker_debian//:wheezy",
  entrypoint = ["echo", "foo"],
)

This docker_build rule produces a Docker container image based on debian that specifies "echo foo" as its ENTRYPOINT.

See https://bazel.build/versions/master/docs/be/docker.html for more options.

cloudbuild.yaml:

steps:
# Build the Docker image and load it into the Docker daemon.
# The loaded image name is the BUILD target's name, prefixed with bazel/.
- name: gcr.io/cloud-builders/bazel
  args: ['run', '//path/to/some:docker_target']
# Re-tag the image to something in your project's gcr.io repository.
- name: gcr.io/cloud-builders/docker
  args: ['tag', 'bazel/path/to/some:docker_target', 'gcr.io/$PROJECT_ID/server']
# Push the image.
images: ['gcr.io/$PROJECT_ID/server']
