本文介绍了使用json_query的ansible过滤器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我这样写:
- name: test for seed
debug:
var: hostvars|json_query("*.ansible_host")
它会打印每个主机.但这不会过滤主机:
And it prints every host. But this does not filter hosts:
- name: test for seed
debug:
var: hostvars|json_query("*[?ansible_host=='192.168.56.101']")
它只是打印一个空列表，而我确定此主机存在.这是相关的库存行:
It just prints an empty list, while I'm sure this host exists. This is the relevant inventory line:
[build-servers]
build-server ansible_host=192.168.56.101
我做错什么了吗?
推荐答案
您应该过滤结果列表，而不是原始哈希:* | [?ansible_host=='192.168.168.21']
You should filter resulting list, not original hash: * | [?ansible_host=='192.168.168.21']
P.S.您通常不想使用debug模块的var选项来打印Jinja语句，请改用msg.
P.S. you usually don't want to use var option of debug module to print Jinja statements, use msg instead.
