drone-docker-tagger

  build:
    image: chatkitinc/drone-docker-tagger
    source_image: source/image:tag
    registry: <your registry>
    username: ${REGISTRY_USERNAME}
    password: ${REGISTRY_PASSWORD}
    tags:
      - tag1
      - tag2
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:rw
