Nativelink Cloud action

This action sets up your repository to use Nativelink Cloud for your Bazel build. We primarily set the values in your .bazelrc (creating or appending this as necessary) and assume you're doing the rest of the Bazel setup.

Usage

1. Goto https://app.nativelink.com and signup for an account
2. Add the following to your Github steps

steps:
  # Other methods of getting Bazel are also usable, but this works well
  - uses: bazel-contrib/[email protected]
    with:
      # Avoid downloading Bazel every time.
      bazelisk-cache: true
      # Build cache is all in Nativelink
      disk-cache: false
      # Share repository cache between workflows.
      repository-cache: true

  - name: Nativelink setup
    uses: TraceMachina/nativelink-action@latest
    with:
      api_key: ${{ secrets.NATIVELINK_API_KEY }}
      account: your-account-here
      prefix: your-account-prefix-here

You'll need to set your-account-here and your-account-prefix-here, as well as the NATIVELINK_API_KEY value.

To determine these values, look at the Quickstart Bazel settings for your account. If your build --remote-cache= value is say for example build --remote_cache=grpcs://cas-tom-parker-shemilt-y0738m.build-faster.nativelink.net, then your-account-here is tom-parker-shemilt and your-account-prefix-here is tom-parker-shemilt-y0738m.

NATIVELINK_API_KEY is your build --remote_header value. e.g. if you have build --remote_header=x-nativelink-api-key=some-key-value, then NATIVELINK_API_KEY is some-key-value
