如何传递第二个列表来玩

Question

我正在尝试将项目列表应用于 when 条件，但它没有按预期工作

在循环中应用的第一个列表

{
"list2": [
{
"apname": "Standard",
"dname": "dom-cn-1",
"name": "cluster-01",
"names": [
"device-cn-c1",
"device-cn-c2"
],
"type": "CpmiGatewayclusterter"
},
{
"apname": "PolicyPKG1",
"dname": "dom-cn-1",
"name": "cluster-cn-02",
"names": [
"device-cn-4",
"device-cn-c3"
],
"type": "CpmiGatewayclusterter"
},
{
"apname": "Standard",
"dname": "dom-cn-2",
"name": "cluster-cn-3",
"names": [
"device-cn-5",
"device-cn-6"
],
"type": "CpmiGatewayclusterter"
},
{
"apname": "Standard",
"dname": "dom-cn-2",
"name": "cluster-cn-4",
"names": [
"device-cn-c7",
"device-cn-c8"
],
"type": "CpmiGatewayclusterter"
},
{
"apname": null,
"dname": "dom-cn-1",
"name": "device-cn-4",
"names": null,
"type": "CpmiclusterterMember"
},
{
"apname": null,
"dname": "dom-cn-2",
"name": "device-cn-5",
"names": null,
"type": "CpmiclusterterMember"
},
{
"apname": null,
"dname": "dom-cn-2",
"name": "device-cn-6",
"names": null,
"type": "CpmiclusterterMember"
},
{
"apname": null,
"dname": "dom-cn-1",
"name": "device-cn-c1",
"names": null,
"type": "CpmiclusterterMember"
},
{
"apname": "Standard",
"dname": "dom-cn-1",
"name": "device-cn-c10",
"names": null,
"type": "simple-gateway"
},
{
"apname": null,
"dname": "dom-cn-1",
"name": "device-cn-c2",
"names": null,
"type": "CpmiclusterterMember"
},
{
"apname": null,
"dname": "dom-cn-1",
"name": "device-cn-c3",
"names": null,
"type": "CpmiclusterterMember"
},
{
"apname": null,
"dname": "dom-cn-2",
"name": "device-cn-c7",
"names": null,
"type": "CpmiclusterterMember"
},
{
"apname": null,
"dname": "dom-cn-2",
"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"
}
]
}

我在以下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">

上面的任务按预期工作，但您可以在 we 条件中看到传递静态值"device-cn-c1"，我想使用不同的项目列表而不是这个静态变量。

示例 list3 有多个设备，我想在 when 条件下循环此列表。(- "'device-cn-c1' in item.names"(

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

我想在条件下使用相同的

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

但是设备名称应该能够像以下示例一样循环

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

这是您要找的条件吗？

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

可以循环include_tasks。例如(或者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) }}"

---

详。list3|intersect(outer_item.names在list3和outer_item.names中创建常见项目的列表。如果此列表为空，则将跳过循环。如果它不是空文件，则将包含loop1.yml。此文件中的循环将循环访问公共项。
