Question

我正在尝试将项目列表应用到when条件，但无法按预期运行

在循环中应用的第一个列表

 {
        "list2": [
            {

            },
            {
                "apname": null,

                "name": "device-cn-c8",
                "names": null,
                "type": "CpmiclusterterMember"
            },
            {
                "apname": null,
                "dname": "dom-cn-1",
                "name": "dom_cn_1",
                "names": null,
                "type": "CpmiHostCkp"
            },
            {
                "apname": null,
                "dname": "dom-cn-2",
                "name": "dom_cn_2",
                "names": null,
                "type": "CpmiHostCkp"
            }
        ]
    }

我在下面的任务中使用上面的列表（list2）

  - name: Create a change request
    snow_record:
      state: present
      table: u_device
      username: admin
      password: password
      instance: dev970066
      data:
        u_name: "{{ item.name }}"
        u_domain: "{{ item.dname }}"
        u_policy: "{{ item.apname }}"
        u_cluster: "{{ item.name }}"
    loop: "{{ list2 }}"
    when:
      - item.type == 'CpmiGatewayCluster'
      - "'device-cn-c1' in item.name

s”

以上任务正在按预期方式工作，但是您可以看到在我们传递一个静态值“ device-cn-c1”的条件下，我想使用其他项目列表代替此静态变量。

example list3有多个设备，我想在条件出现时循环此列表。（-“ item.names中的'device-cn-c1'”）

  list3:
    - device-cn-c1
    - device-cn-c2
    - device-cn-c3
    - device-cn-c10

我想在条件满足时使用

when:
  - item.type == 'CpmiGatewayCluster'
  - "'device-cn-c1' in item.name

但是设备名称应该可以像下面的示例一样循环

1.

when:
  - item.type == 'CpmiGatewayCluster'
  - "'device-cn-c1' in item.names" 


    when:
      - item.type == 'CpmiGatewayCluster'
      - "'device-cn-c2' in item.names"  


    when:
      - item.type == 'CpmiGatewayCluster'
      - "'device-cn-c3' in item.names"  

    when:
      - item.type == 'CpmiGatewayCluster'
      - "'device-cn-c4' in item.names"

Answer 1

这是您要寻找的条件吗？

when: list3|intersect(item.names)|length > 0

可以循环include_tasks。例如（或更确切地说是一个提示）

- include_tasks: loop1.yml
  loop: "{{ list2 }}"
  loop_control:
    loop_var: outer_item
  when:
    - outer_item.type == 'CpmiGatewayCluster'
    - list3|intersect(outer_item.names)|length > 0

$ cat loop1.yml
- debug:
    msg: "{{ outer_item.apname }} - {{ item }}"
  loop: "{{ list3|intersect(outer_item.names) }}"

细节。 list3|intersect(outer_item.names在list3和outer_item.names中创建常用项目列表。如果此列表为空，则将跳过循环。如果不为空，则将包含文件loop1.yml。该文件内的循环将遍历常见项目。

如何通过第二个清单播放
