Ansible从命令行获取用户名

问题描述

在我的剧本中，我经常引用用户名(完全是用户名"ubuntu").

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

是否有内置的说法从命令行中传递的值中获取"?

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

我知道我能做

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

然后我可以在剧本中使用 {{user}} ，但是两次定义用户感觉很奇怪.

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

推荐答案

正如伍德汉姆(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 }} )

但是您不必自己在清单文件中对其进行定义.

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

您可以在以下位置进行定义:

You can define it in:

1.您的剧本(如果您使用ansible-playbook):请参阅Playbooks手册

- name: Some play
  hosts: all
  remote_user: ubuntu

2.在库存文件中:请参阅广告资源手册

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

3.如您所说，在命令行上:

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

4.一个可配置文件，作为 remote_user 指令.请参阅有关配置文件的手册

ansible配置文件可以放在当前文件夹 ansible.cfg ，您的homedir .ansible.cfg 或/etc/ansible/ansbile.cfg中.

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
