ansible - 双循环 Ansible

Question

我有一个这样的对象

objs:
    - { key1: value1, key2: [value2, value3] }
    - { key1: value4, key2: [value5, value6] }

我想创建以下文件

value1/value2
value1/value3
value4/value5
value4/value6

但我不知道如何使用 with_items

进行双循环

Answer 1

看看 Ansible's docs for loops 中的 with_subelements .

1. 您需要创建目录:
2. 迭代objs并创建文件:

这是一个例子:

---

- hosts: localhost
  gather_facts: no
  vars:
    objs:
      - { key1: value1, key2: [ value2, value3] }
      - { key1: value4, key2: [ value5, value6] }
  tasks:
    - name: create directories
      file: path="{{ item.key1 }}"  state=directory
      with_items:
        objs

    - name: create files
      file: path="{{ item.0.key1 }}/{{ item.1 }}"  state=touch
      with_subelements:
        - objs
        - key2

输出非常不言自明，第二个循环按照您需要的方式迭代值:

PLAY [localhost] ************************************************************** 

TASK: [create files] ********************************************************** 
changed: [localhost] => (item={'key2': ['value2', 'value3'], 'key1': 'value1'})
changed: [localhost] => (item={'key2': ['value5', 'value6'], 'key1': 'value4'})

TASK: [create files] ********************************************************** 
changed: [localhost] => (item=({'key1': 'value1'}, 'value2'))
changed: [localhost] => (item=({'key1': 'value1'}, 'value3'))
changed: [localhost] => (item=({'key1': 'value4'}, 'value5'))
changed: [localhost] => (item=({'key1': 'value4'}, 'value6'))

PLAY RECAP ******************************************************************** 
localhost                  : ok=2    changed=2    unreachable=0    failed=0
