我对 ansible (v2.3) 的 docker_container 模块有疑问。当我尝试传递env_file剧本中的属性时，出现错误：no such file or directory

---
- hosts: preprod-api
  become: yes
  gather_facts: true
  tasks:
    - name: test configuration
      docker_container:
        name: "backend"
        image: "backend"
        state: started
        exposed_ports:
          - 80
        volumes:
          - /opt/application/i99/current/logs
        user: ansible
        env_file: 
          - "/opt/application/i99/current/backend/backend-PreProd-config.list"

我尝试使用 ansible 服务器上存在的一个文件和目标服务器上存在的一个文件，得到相同的结果。

这是错误：

`fatal: [my_hostname]: FAILED! => {"changed": false, "failed": true, "module_stderr": "Shared connection to my_hostname closed.\r\n", 
"module_stdout": "Traceback (most recent call last):
    File \"/tmp/ansible_rySqS2/ansible_module_docker_container.py\", 
    line 2036, in <module>    main() File \"/tmp/ansible_rySqS2/ansible_module_docker_container.py\", 
    line 2029, in …

我有一个像这样的字符串变量RCD_APIS=backend,api-alerting,api-tracking,api-versioning，其中包含我的泊坞窗图像的名称。我需要将它分成一个数组并循环它，这样我就可以提取每个泊坞窗图像

我尝试过 with_sequence 循环，但我只得到索引 (1,2,3,..)

- name: pull images from registry
  docker_image:
    name: "hostname:5000/{{ RCD_APIS.split(',') }}"
    pull: true
    state: present
    tag: "{{RCD_VERSION_CURRENT}}"
  with_sequence: count={{ RCD_APIS|count }}

我也尝试过 with_item 循环，但它不起作用，所以我尝试调试：

 vars:
    - container: "{{ RCD_APIS }}"
 tasks:
    - name: pull images from registry debug
      debug: var={{item|basename}}
      with_items: container.split(',')

我得到类似的东西：

(item=container.split(',')) => {
         "container.split(',')": [
         "backend", 
         "api-alerting", 
         "api-tracking", 
         "api-versioning", 
         "connecteur-gdfa", 
         "api-batch", 
         "ihm"
     ], 
     "item": "container.split(',')"
}

那么我如何循环该数组（如 foreach）并执行docker pull backend, docker pull api-alerting...？
