  Wrapper around docker/setup-buildx-action that defaults to the in-cluster
  buildkit service running in the gitea namespace of the aceofbase cluster.
  Lets workflow authors skip the boilerplate of pointing setup-buildx at a
  remote driver.

inputs:
  endpoint:
    description: 'BuildKit TCP endpoint. Defaults to the in-cluster service.'
    required: false
    default: 'tcp://buildkit.gitea.svc.cluster.local:1234'
  version:
    description: 'buildx version to install (passed through).'
    required: false
    default: 'latest'

runs:
  using: composite
  steps:
    - uses: docker/setup-buildx-action@v3
      with:
        driver: remote
        endpoint: ${{ inputs.endpoint }}
        version: ${{ inputs.version }}
