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

问题描述

具有这样的字典:

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子句中搜索此词典中的所有值?

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

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

但是我想搜索所有值以确保没有匹配项.

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

换句话说，我不想在该数据结构的任何位置找到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

如果要使用json_query(需要使用ansible 2.2)，则可以执行以下操作来搜索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"

或者如果您要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变体.
