Ansible with_dict 需要一个 dict

Tec*_*eer 7 ansible ansible-2.x

我知道这个问题之前已经被问过很多次了,但我一定在这里遗漏了一些东西!

这是重现问题的最小剧本。

这是剧本:

---
- hosts:
    - localhost
  gather_facts: false
  vars:
    zones_hash:
      location1:
        id: 1
        control_prefix: '10.1.254'
        data_prefix: '10.1.100'
      location2:
        id: 2
        control_prefix: '10.2.254'
        data_prefix: '10.2.100'
  tasks:
    - name: "test1"
      debug: var="zones_hash"

    - name: "test2"
      debug: var="item"
      with_dict:
      - "{{ zones_hash }}"

这是输出:

我希望 task2 中打印的 item 变量包含(例如):

key: location1
value: {
  id: 1
  control_prefix: '10.1.254'
  data_prefix: '10.1.100'
}

我们缺少什么?

看起来 Ansible 的文档需要更新,或者您发现了一个错误。 http://docs.ansible.com/ansible/latest/playbooks_loops.html#looping-over-hashes使用您的with_dict语法,但似乎不再起作用。字典需要与with_dict.

- name: "test2"
  debug: var="item"
  with_dict: "{{ zones_hash }}"

with_dict:
  - "{{ zones_hash }}"

声明一个以 dict 为第一个索引的列表,Ansible 理所当然地抱怨,因为它需要一个 dict。

kfreezy 提到的解决方案有效,因为它实际上提供了一个字典with_dict而不是一个列表:

with_dict: "{{ zones_hash }}"
