我有一个变量yaml文件:
---
apps:
- client
- node
- gateway
- ic
- consul
这个任务:
- name: register if apps exists
stat: path="/etc/init.d/{{ item }}"
with_items: apps
register: "{{ item.stat.exists }}exists"
我需要为每个应用程序设置一个变量,其值为true或false,无论文件是否存在:
clientexists = true
nodeexists = true
gatewayexists = false
icexists = true
consulexists = false
出于某种原因,item
和exists
concat无效。
我怎样才能实现?

试试这个希望这会帮助你。在Stats.yml
中循环,然后msg
字段将包含您想要的输出。
Variables.yml Here we are defining variables

apps:
- client
- node
- gateway
- ic
- consul
<强> Stats.yml 强>

- hosts: localhost
name: Gathering facts
vars_files:
- /path/to/variables.yml
tasks:
- name: "Here we are printing variables"
debug:
msg: "{{apps}}"
- name: "Here we are gathering stats and registering it"
stat:
path: "/etc/init.d/{{item}}"
register: folder_stats
with_items:
- "{{apps}}"
- name: "Looping over registered variables, Its msg field will contain desired output"
debug:
msg: "{{item.invocation.module_args.path}}: {{item.stat.exists}}"
with_items:
- "{{folder_stats.results}}"
...
folder_stats
将包含整个结果,单独引用单个结果你可以在你的剧本中使用它。
folder_stats.results[0].stat.exists
folder_stats.results[1].stat.exists
folder_stats.results[2].stat.exists
folder_stats.results[3].stat.exists
