使用外部MySQL主机进行zipkin跟踪

Question

我正在向我的服务添加zipkin跟踪，并尝试使用外部MySQL而不是本地mysql来存储跟踪，这可能吗

我正在为mysql使用默认的docker compose，如下所示

  version: '2'

    services:
      storage:
        image: openzipkin/zipkin-mysql
        container_name: mysql
        # Uncomment to expose the storage port for testing
        # ports:
        #   - 3306:3306

      # The zipkin process services the UI, and also exposes a POST endpoint that
      # instrumentation can send trace data to. Scribe is disabled by default.
      zipkin:
        image: openzipkin/zipkin
        container_name: zipkin
        # Environment settings are defined here https://github.com/openzipkin/zipkin/tree/1.19.0/zipkin-server#environment-variables
        environment:
          - STORAGE_TYPE=mysql
          # Point the zipkin at the storage backend
          - MYSQL_HOST=mysql
          # Uncomment to enable scribe
          # - SCRIBE_ENABLED=true
          # Uncomment to enable self-tracing
          # - SELF_TRACING_ENABLED=true
          # Uncomment to enable debug logging
          # - JAVA_OPTS=-Dlogging.level.zipkin=DEBUG -Dlogging.level.zipkin2=DEBUG
        ports:


     # Port used for the Zipkin UI and HTTP Api
      - 9411:9411
      # Uncomment if you set SCRIBE_ENABLED=true
      # - 9410:9410
    depends_on:
      - storage

  # Adds a cron to process spans since midnight every hour, and all spans each day
  # This data is served by http://192.168.99.100:8080/dependency
  #
  # For more details, see https://github.com/openzipkin/docker-zipkin-dependencies
  dependencies:
    image: openzipkin/zipkin-dependencies
    container_name: dependencies
    entrypoint: crond -f
    environment:
      - STORAGE_TYPE=mysql
      - MYSQL_HOST=mysql
      # Add the baked-in username and password for the zipkin-mysql image
      - MYSQL_USER=zipkin
      - MYSQL_PASS=zipkin
      # Uncomment to see dependency processing logs
      # - ZIPKIN_LOG_LEVEL=DEBUG
      # Uncomment to adjust memory used by the dependencies job
      # - JAVA_OPTS=-verbose:gc -Xms1G -Xmx1G
    depends_on:
      - storage

要使用外部sql我需要进行哪些更改？
