Ansible，docker_container和depends_on

我正在使用ansible和docker_container模块。但是，当我启动剧本时，出现类似以下错误：

"'depends_on' is not a valid attribute for a Task"

这是我的剧本：

- name: Docker-compose
  hosts: localhost
  connection: local
  gather_facts: no  
  tasks:
    - name: Start selenium hub
      docker_container:
        name: hub
        image: selenium:latest
        state: started
        restart: yes
        ports:
          - "4444:4444"

    - name: Start chromedriver
      docker_container:
        name: chromedriver
        image: chromedriver:latest
        state: started
        restart: yes
        depends_on:
          - "hub"
        links:
          - "hub:hub"  
        env:
            VNC_ENABLED: true
            EXPOSE_X11: true
        ports:
          - "5900:5900"

如您所见，名称为“ chromedriver”的容器取决于“ hub”。我怎样才能做到这一点？
