问题描述

我正在尝试检查提供的版本是否为有效的受支持版本.我已在变量中设置了可接受版本的列表,并且如果提供的版本不在列表中,则我想退出该任务.但是,我不确定该怎么做.

I'm trying to check if the version supplied is a valid supported version. I've set the list of acceptable versions in a variable, and I want to fail out of the task if the supplied version is not in the list. However, I'm unsure of how to do that.

#/role/vars/main.yml
---
  acceptable_versions: [2, 3, 4]

#/role/tasks/main.yml
---
  - fail:
      msg: "unsupported version"
      with_items: "{{acceptable_versions}}"
      when: "{{item}} != {{version}}"

  - name: continue with rest of tasks...

以上是我想要做的事情,但是我无法弄清楚是否有一种方法可以为故障模块构造列表包含"调用.

Above is sort of what I want to do, but I haven't been able to figure out if there's a one line way to construct a "list contains" call for the fail module.

推荐答案

在有条件的情况下不需要{{}}.您要搜索的是:

You do not need {{}} in when conditions. What you are searching for is:

- fail: msg="unsupported version"
  when: version not in acceptable_versions
