Installation (using Helm)

Make sure both kubectl and helm are installed.
When creating a new workspace, take a look at the Kubectl recipe and the Helm recipe.
Install bazel buildfarm on your k8s cluster using the official helm chart:

helm install \
  -n bazel-buildfarm \
  --create-namespace \
  bazel-buildfarm \
  oci://ghcr.io/bazelbuild/buildfarm \
  --version "0.2.4"

kubectl port-forward service/bazel-buildfarm-server -n bazel-buildfarm 8980:8980 --address 0.0.0.0

Create the following bazel workspace file structure for testing:

main.cc

#include <iostream>
 
int main( int argc, char *argv[] )
{
  std::cout << "Hello, World!" << std::endl;
}

BUILD

cc_binary(
    name = "main",
    srcs = ["main.cc"],
)

WORKSPACE

Leave this file empty.

Run bazel run :main to verify the build locally.

bazel build --remote_executor=grpc://<your-devbox>:8980 :main

bazel build --remote_cache=grpc://<your-devbox>:8980 :main
