Docker Build only specific target

Drone Support

is there a way in docker plugin to build only a specific target?
On my machine I would just provide DOCKER_BUILDKIT=1, is there a way to achieve this with docker plugin?

I haven’t tried the latest Drone, but I did this some months ago with Drone 0.8:

  build-image:
    image: docker:18.09
    commands:
      - >-
        docker image build
        -f Dockerfile
        --tag $DOCKER_REPO:${DRONE_COMMIT}
        --tag $DOCKER_REPO:latest
        --pull
        --target production
        --build-arg DRONE_BRANCH=${DRONE_BRANCH}
        --build-arg DRONE_COMMIT=${DRONE_COMMIT}
        --label org.label-schema.schema-version=1.0
        --label org.label-schema.build-date=$(date -u +'%Y-%m-%dT%H:%M:%SZ')
        --label org.label-schema.vcs-ref=${DRONE_COMMIT}
        --label org.label-schema.vcs-url=https://example.com/scm/org/repo.git
        .
      - echo $DOCKER_PASSWORD | docker login --username $DOCKER_USERNAME --password-stdin
      - docker image push $DOCKER_REPO:${DRONE_COMMIT}
      - docker image push $DOCKER_REPO:latest
      - docker image rm $DOCKER_REPO:${DRONE_COMMIT} $DOCKER_REPO:latest
      - docker image prune -f
    environment:
      - DOCKER_BUILDKIT=1
      - DOCKER_REPO=org/repo
    secrets:
      - docker_username
      - docker_password
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    when:
      branch:
        - master
      event: push
