Question

我无法完成以下工作

柱：


    rabbitmq:
      version: '3.5.6'
      users:
        tmpchq_user:
          password: RvdeXurQ
      vhosts:
        tmpchq:
          - user: tmpchq_user
            permission: '".*" ".*" ".*"'
          - user: default_user
            permissions: '".*" ".*" ".*"'
        default:
          - user: temp
            permission: '".*" ".*" ".*"'

状态：


    {% for vhost in salt['pillar.get']('rabbitmq:vhosts') %}
      {% for items in salt['pillar.get']('rabbitmq:vhosts:{{ vhost }}') %}
    config_rabbitmq:
      cmd.run:
        - name: |
            rabbitmqctl add_vhost {{ vhost }} user {{ items['user'] }} permissions {{ items['permissions'] }}
        - cwd: /
        - shell: /bin/bash
      {% endfor %}
    {% endfor %}

现在，如果我在python中解决这个问题，它可以正常工作：


    >>> x = {'rabbitmq': {'users': {'tmpchq_user': {'password': 'RvdeXurQ'}},
    ...               'version': '3.5.6',
    ...               'vhosts': {'default': [{'permission': '".*" ".*" ".*"',
    ...                                       'user': 'temp'}],
    ...                          'tmpchq': [{'permission': '".*" ".*" ".*"',
    ...                                      'user': 'tmpchq_user'},
    ...                                     {'permission': '".*" ".*" ".*"',
    ...                                      'user': 'default_user'}]}}}
    >>> for vhost in x['rabbitmq']['vhosts']:
    ...     for items in x['rabbitmq']['vhosts'][vhost]:
    ...         print(vhost, items['user'], items['permission'])
    ...         
    ...     
    ... 
    default temp ".*" ".*" ".*"
    tmpchq tmpchq_user ".*" ".*" ".*"
    tmpchq default_user ".*" ".*" ".*"

时髦的部分是我不会因为盐而失败或成功。我什么都没得到：


    [root@salt-master srv]# salt 'client01p' state.sls rabbitmq.install_exp
    client01p:

    Summary for client01p
    -----------
    Succeeded: 0
    Failed:   0
    -----------
    Total states run:    0
    Total run time:  0.000 ms

任何想法？还要忽略这个命令只使用组合指令，我只是试图让嵌套工作，这只是一个虚构的例子。

{% for items in salt['pillar.get']('rabbitmq:vhosts:{{ vhost }}') %}

这是错误的。您在{{ }}块内不需要{% %}。请改用jinja的~字符串连接运算符：

{% for items in salt['pillar.get']('rabbitmq:vhosts:'~vhost) %}

此外，您应该知道，如果支柱中的'rabbitmq:vhosts:'~vhost为空，您将收到错误，因为您无法迭代None。

另外，我会像这样编写你的嵌套for循环：

{% for vhost, items in salt['pillar.get']('rabbitmq:vhosts', {}).items() %}
  {% for item in items %}
