Ansible 使用'；无法按预期在数组中循环

我正在尝试创建一个新的Ansible playbook来管理一些应用程序服务

我的剧本是：

- hosts: MyHost
  gather_facts: no
  vars:
    Services: []
  tasks:
  - name: "Search for service to manage"
    find:
      path: "/data/mgwroot/applications"
      file_type: directory
      patterns: '*{{ ELD }}*'
    register: FoundServices

  - name: "Add found services to array"
    no_log: true
    set_fact:
      Services: "{{ Services + [item.path | basename] }}"
    with_items: "{{ FoundServices.files }}"

  - name: "Display array content"
    debug:
      msg: "{{ Services }}"

  - name: "- TASK A -"
    shell: "echo {{ item.0 }} {{ item.1 }}"
    with_nested:
    - [ 'stop', 'start' ]
    - [ "{{ Services }}" ]

  - name: "- TASK B -"
    shell: "echo {{ item.0 }} and {{ item.1 }}"
    with_nested:
      - ['stop', 'start']
      - ['serviceA', 'serviceB']

• 查找要管理的服务
• 将这些服务添加到阵列中
• 循环此阵列以停止和启动我的不同服务

我做了这个剧本：

- hosts: MyHost
  gather_facts: no
  vars:
    Services: []
  tasks:
  - name: "Search for service to manage"
    find:
      path: "/data/mgwroot/applications"
      file_type: directory
      patterns: '*{{ ELD }}*'
    register: FoundServices

  - name: "Add found services to array"
    no_log: true
    set_fact:
      Services: "{{ Services + [item.path | basename] }}"
    with_items: "{{ FoundServices.files }}"

  - name: "Display array content"
    debug:
      msg: "{{ Services }}"

  - name: "- TASK A -"
    shell: "echo {{ item.0 }} {{ item.1 }}"
    with_nested:
    - [ 'stop', 'start' ]
    - [ "{{ Services }}" ]

  - name: "- TASK B -"
    shell: "echo {{ item.0 }} and {{ item.1 }}"
    with_nested:
      - ['stop', 'start']
      - ['serviceA', 'serviceB']

PLAY [MyHost] *************************************************************************************************************************************************************************

TASK [Search for service to manage] ******************************************************************************************************************************************************
Thursday 19 November 2020  13:25:46 +0100 (0:00:00.109)       0:00:00.109 *****
ok: [MyHost]

TASK [Add found service to array] ********************************************************************************************************************************************************
Thursday 19 November 2020  13:25:48 +0100 (0:00:01.260)       0:00:01.370 *****

Thursday 19 November 2020  13:25:48 +0100 (0:00:00.058)       0:00:01.429 *****
ok: [MyHost] => {
    "msg": [
        "PREPRO_MVZV14_batch",
        "PREPRO_MVZV14_tp"
    ]
}

TASK [- TASK A -] ************************************************************************************************************************************************************************
Thursday 19 November 2020  13:25:48 +0100 (0:00:00.038)       0:00:01.467 *****
changed: [MyHost] => (item=[u'stop', u'PREPRO_MVZV14_batch', u'PREPRO_MVZV14_tp'])
changed: [MyHost] => (item=[u'start', u'PREPRO_MVZV14_batch', u'PREPRO_MVZV14_tp'])

TASK [- TASK B -] ************************************************************************************************************************************************************************
Thursday 19 November 2020  13:25:49 +0100 (0:00:01.116)       0:00:02.583 *****
changed: [MyHost] => (item=[u'stop', u'serviceA'])
changed: [MyHost] => (item=[u'stop', u'serviceB'])
changed: [MyHost] => (item=[u'start', u'serviceA'])
changed: [MyHost] => (item=[u'start', u'serviceB'])

结果并不像预期的那样工作：-（：

• “-TASK B-”，静态列表中的哪个循环工作正常，但
• “-TASK A-”，在我的dynamics数组上的循环无效

这是结果：

- hosts: MyHost
  gather_facts: no
  vars:
    Services: []
  tasks:
  - name: "Search for service to manage"
    find:
      path: "/data/mgwroot/applications"
      file_type: directory
      patterns: '*{{ ELD }}*'
    register: FoundServices

  - name: "Add found services to array"
    no_log: true
    set_fact:
      Services: "{{ Services + [item.path | basename] }}"
    with_items: "{{ FoundServices.files }}"

  - name: "Display array content"
    debug:
      msg: "{{ Services }}"

  - name: "- TASK A -"
    shell: "echo {{ item.0 }} {{ item.1 }}"
    with_nested:
    - [ 'stop', 'start' ]
    - [ "{{ Services }}" ]

  - name: "- TASK B -"
    shell: "echo {{ item.0 }} and {{ item.1 }}"
    with_nested:
      - ['stop', 'start']
      - ['serviceA', 'serviceB']

• 停止预处理MVZV14\U批次
• 开始预处理MVZV14\U批次
• 停止预处理MVZV14\U tp
• 启动预处理MVZV14\U tp

有人能解释我做错了什么吗

谢谢大家！

我找到了解决方案

替换 -[“{{Services}}”] 到 -“{{Services}}”
