Ansible 从命令行获取用户名 [英] Ansible get the username from the command line

问题描述

在我的剧本中，我经常引用用户名(特别是ubuntu").

In my playbooks I reference username (exclusively its "ubuntu") a lot.

是否有内置的方式说从命令行中传递的值中获取它"?

Is there a built in way to say "get it from the value passed in the command line"?

我知道我能做到

ansible-playbook <task> -u <user> -K --extra-vars "user=<user>"

然后我可以在 playbook 中使用 {{user}} ，但是定义用户两次感觉很奇怪.

and then I can use {{user}} in the playbook, but it feels odd defining the user twice.

推荐答案

正如 Woodham 所说，代表连接用户的 ansible 变量是

As Woodham stated, the ansible variable that represents the connecting user is

{{ ansible_user }} (Ansible < 2.0 was {{ ansible_ssh_user }} )

但您不必在清单文件本身中定义它.

But you don't have to define it in the inventory file per se.

你可以在:

1.你的游戏，如果你使用 ansible-playbook:查看手册手册

- name: Some play
  hosts: all
  remote_user: ubuntu

2.在清单文件中:查看库存手册

[all]
other1.example.com     ansible_user=ubuntu (Ansible < 2.0 was ansible_ssh_user)

3.正如您所说，在命令行上:

ansible-playbook -i inventory -u ubuntu playbook.yml

4.作为 remote_user 指令的 ansible 配置文件.查看配置文件手册

4. An ansible config file as a remote_user directive. See the manual on a config file

ansible 配置文件可以放在当前文件夹 ansible.cfg、你的 homedir .ansible.cfg 或 /etc/ansible/ansbile.cfg.

The ansible config file can be placed in the current folder ansible.cfg, your homedir .ansible.cfg or /etc/ansible/ansbile.cfg.

[defaults]
remote_user=ubuntu
