如何通过第二个列表来播放 [英] How to pass second list in to play
问题描述
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
I am trying to apply list of items in to when condition and it is not working as expected
循环中应用的第一个列表
First list which is applied in the loop
{
"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"
}
]
}
我在下面的任务中使用上面的列表 (list2)
I am using the above list (list2) in to the below task
- 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"
上述任务按预期工作，但您可以在传递静态值device-cn-c1"的我们条件中看到，我想使用不同的项目列表而不是这个静态变量.
above task is working as expected but you can see in the we condition passing a static value "device-cn-c1", i want to use different list of items instead of this static variable.
示例 list3 有多个设备，我想在 when 条件下循环此列表.(-item.names 中的‘device-cn-c1’")
example list3 have multiple devices, i want to loop this list in when condition. (- "'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
I want to use the same when condition
when:
- item.type == 'CpmiGatewayCluster'
- "'device-cn-c1' in item.name
但是设备名称应该能够像下面的例子一样循环
But device name should be able to loop like below example
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"
推荐答案
这是您要寻找的条件吗?
Is this the condition you're looking for?
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)
It is possible to loop include_tasks. For example (or rather a hint)
- 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) }}"
<小时>细节.list3|intersect(outer_item.names 在 list3 和 outer_item.names 中创建一个公共项目列表.如果此列表为空，循环将被跳过.如果它不是空文件 loop1.yml 将被包含在内.此文件中的循环将遍历公共项目.
Details.
list3|intersect(outer_item.names creates a list of common items in in list3 and outer_item.names. If this list is empty the loop will be skipped. If it's not empty file loop1.yml will be included. The loop inside this file will iterate over the common items.
