在 Ansible 中搜索字典值 [英] Search Dictionary Values in Ansible

问题描述

有一本这样的字典:

ossec_datacenter:
  atlanta:
    hostname: 'server1.fakedomain.net'
    ip: '192.168.12.170'
    port: '1515'
  miami:
    hostname: 'server2.fakedomain.net'
    ip: '192.168.20.31'
    port: '1514'
  dallas:
    hostname: 'server2.fakedomain.net'
    ip: '192.168.20.20'
    port: '1515'

如何在我的 when 子句中搜索此字典中的所有值?

How would I search for all values in this dictionary in my when clause?

我可以使用 ossec_datacenter[ossec_dc]['hostname']

但我想搜索所有值以确保不存在匹配项.

But I want so search all values to make sure no matches are present.

换句话说，我不希望在该数据结构的任何地方找到 inventory_hostname 或 IP.

In other words I don't want the inventory_hostname nor the IP to be found anywhere in that data structure.

推荐答案

如果你想使用json_query(需要ansible 2.2)你可以这样做来搜索ip和主机名:

If you want to use json_query (requires ansible 2.2) you can do this to search ip and hostname:

    - name: find inventory_hostname
      set_fact:
        found: True
      with_items:
        - "{{ ossec_datacenter | json_query('*.ip') }}"
        - "{{ ossec_datacenter | json_query('*.hostname') }}"
      when: "inventory_hostname == item"

或者如果您想搜索数据中心中的任何键(ip、主机名或端口):

or if you want to search any of the keys in the datacenters (ip, hostname, or port):

- name: find inventory_hostname
  set_fact:
    found: True
  with_items: "{{ ossec_datacenter | json_query('*.*') }}"
  when: "inventory_hostname == item"

然后测试 found 变量.
