当状态存在时，Ansible lineinfile 找不到特定的字符串

我想检查admin_token我的文件中是否定义了keystone.conf。为此，我想使用 Ansible。但是，即使文件中存在该属性，任务也会失败。

我用该lineinfile模块比较了两个任务（相同的正则表达式，状态先出现然后消失）。在第一个任务中，Ansible 没有找到该行。但是，它在第​​二个任务中找到了它。任何时候都不会对文件进行任何修改。

这是从哪里来的？

该lineinfile模块旨在编辑文件，而不仅仅是检查其内容，因此要求您line在指定时提供替换state=present。由于您没有指定替换，因此您会收到错误："line is required with state=present"。

admin_token如何解决问题取决于您在问题中未提供的背景。但我猜您应该在替换中设置line。例如：

    line: "admin_token={{keystone_admin_token}}"
