在 Ansible 中解析一个 JSON 输出以嵌套显示信息
Parse a JSON Output in Ansible to display information in nested display
我正在尝试 运行 一个查询我们的 F5 特定池并仅显示我需要的内容的剧本。我可以直接在 ltm_pools 下解析任何数据，但如果它是像“成员”这样的子集，我无法为此过滤特定信息。我想过滤成员子集的特定信息。您可以看到我将成员列为输出显示，但它显示成员下的每个字段。我想过滤特定字段，例如“成员”字段下的“姓名”。
查看 JSON 输出：

这是我的剧本：
- hosts: localhost
tasks:
- name: collect device info
bigip_device_info:
gather_subset:
- ltm-pools
delegate_to: localhost
register: f5pools
# Show the name, IP address, port and status of a virtual server
- name: Display Config for a specific Virtual Server using a variable
debug:
var: item
loop: "{{ f5pools | json_query(pool_name) }}"
vars:
pool_name: "ltm_pools[?name=='{{ poolName }}'].{name: name, Method: lb_method, Members: members Monitors: monitors}"
您可以在多选中嵌套 JMESPath 查询，在您的情况下，以实现您要查找的内容。
所以不用普通的
Members: members
在你的多选中，你可以使用类似
的东西
Members: members[*].{name: name}
鉴于剧本：
