我对ansible相当新，我试图确定如何测试传递给我的playbook匹配的子串列表的变量。
我尝试过类似下面的内容。循环遍历我的badcmd列表，然后测试它是否在传递的变量中。
vars:
badcmds:
- clear
- no
tasks:
- name: validate input
debug:
msg: " {{ item }}"
when: item in my_command
with_items: "{{ badcmds }}"
我收到以下错误：
"msg": "The conditional check 'item in my_command' failed.
The error was: Unexpected templating type error occurred on
({% if item in my_command %} True {% else %} False {% endif %}):
coercing to Unicode: need string or buffer, bool found
非常感谢。

会自动转换为布尔- no。你应该使用＆＃34; no＆＃34;使Ansible将变量视为字符串。没有引号：
false输出：
---
- hosts: localhost
connection: local
gather_facts: false
vars:
badcmds:
- clear
- no
my_command: clear
tasks:
- name: print variable
debug:
msg: "{{ item }}"
with_items:
- "{{ badcmds }}"
我想你应该在引号中加上TASK [print variable] ***********************************************************************************************************************************************************************************************
ok: [localhost] => (item=None) => {
"msg": "clear"
}
ok: [localhost] => (item=None) => {
"msg": false
}
，因为这不是你的意图。
进行循环并检查变量是否与no列表中的任何项匹配，您可以使用：
badcmds希望有所帮助
