有条件地将Ansible角色设置为默认值 [英] Set Ansible role defaults conditionally

问题描述

伪代码:

如果env是de，则将变量名设置为hello，否则，如果env是prod，则将变量名设置为bye.

If env is de, set variable name to hello else if env is prod, set variable name to bye.

我尝试了 https://serverfault.com/questions/715769/ansible-change-default-value-according to a-condition

 - name: setting variable
   set_fact: name="hello"
   when: "{{ env }}" == "de"

 - name: setting variable
   set_fact: name="bye"
   when: "{{ env }}" == "prod"

错误！角色试用"的default/main.yml文件必须包含一个 变量字典

ERROR! The default/main.yml file for role 'trial' must contain a dictionary of variables

推荐答案

根据我的要求，它需要按角色进行操作.因此，操作如下:

As per my requirement, it needs to be done in role.So it is done as follows:

名称:"{％如果env =='de'％} hello {％elif env =='prod'％}再见{％endif％}"

name: "{% if env == 'de' %}hello{% elif env == 'prod' %}bye{% endif %}"
