可以使用 ansible 变量在剧本中声明主机吗? [英] Can ansible variables be used to declare hosts in a playbook?

问题描述

我有一个格式如下的剧本:

I have a playbook in the format below:

---
- hosts: myIP
  tasks:
  - name: Install a yum package in Ansible example
    yum:
      name: ThePackageIWantToInstall
      state: present

其中 myIP 和 ThePackageIWantToInstall 是变量.

where myIP and ThePackageIWantToInstall are variables.

当作业模板运行时，我希望额外变量弹出窗口中的用户能够使用:

When the job template runs, I would like the user in the extra variables popup to be able to go with:

myIP = 192.168.1.1
ThePackageIWantToInstall = nano

由于文档没有提供通过作业模板提供变量的示例，这可能吗?

As the documentation doesn't provide an example of supplying a variable via a job template, is this possible?

推荐答案

是.

- name: Do The Thing
  hosts: "{{ foo }}"
  roles:
   - "{{ role }}"

需要胡子和引号.

(我不使用这个，但有人建议修改它，谢谢...)

foo: 值
