多次创建相同的角色，但具有不同的项目 [英] Creating multiple times the same role, but with different items

问题描述

我有一个剧本，在我的机器中准备了 3 个不同的 Vagrant，所以我创建了一个角色来创建这个 Vagrant.我没有找到正确的语法.看起来 roles 不是模块，所以我不没有所有选项，只有教程.

I have a playbook that prepare 3 different Vagrants in my machine, so I have create a role that create this Vagrant. I don't find the correct syntax. It looks like roles is not a module, so I don't have all options, only tutorials.

剧本文件:

- hosts: localhost
  connection: local

  roles :
    - role: vagrant
      with_items:
        - {index: 1, ip: 192.168.222.1, name: mongo1, user: nicorama }
        - {index: 2, ip: 192.168.222.2, name: mongo2, user: nicorama }
        - {index: 3, ip: 192.168.222.3, name: mongo3, user: nicorama }

以及 vagrant 角色中的任务

And the tasks in the vagrant role

- file: path=/linux/{{item.name}} state=directory  owner={{item.user}} group={{item.user}} mode="u=rwx,g=rwx,o=rx"
- file: src=playbook.yml dest=/linux/{{item.name}}
- template: src=Vagrantfile dest=/linux/{{item.name}}/Vagrantfile

错误是item.name"未定义.在角色内部使用 with_items 确实有效，但它甚至会伤害我祖母的眼睛

The error is 'item.name' undefined. It does work using with_items inside the role, but it would even hurt my grandmother eyes

- file: path=/linux/{{item.name}} state=directory  owner={{item.user}} group={{item.user}} mode="u=rwx,g=rwx,o=rx"
  with_items:
        - {index: 1, ip: 192.168.222.1, name: mongo1, user: nicorama }
        - {index: 2, ip: 192.168.222.2, name: mongo2, user: nicorama }
        - {index: 3, ip: 192.168.222.3, name: mongo3, user: nicorama }
- copy: src=playbook.yml dest=/linux/{{item.name}}/playbook.yml
  with_items:
        - {index: 1, ip: 192.168.222.1, name: mongo1, user: nicorama }
        - {index: 2, ip: 192.168.222.2, name: mongo2, user: nicorama }
        - {index: 3, ip: 192.168.222.3, name: mongo3, user: nicorama }
...

推荐答案

再次阅读您的问题，我注意到您实际上并没有提到它必须是某种循环.也许应用 3 次不同参数的相同角色适合您的需求:

Reading your question again, I noticed you did actually not mention it has to be some kind of loop. Maybe applying 3 times the same role with different parameters suits your needs:

- hosts: localhost
  connection: local

  roles :

    - role: vagrant
      index: 1
      ip: 192.168.222.1
      name: mongo1
      user: nicorama

    - role: vagrant
      index: 2,
      ip: 192.168.222.2
      name: mongo2
      user: nicorama

    - role: vagrant
      index: 3
      ip: 192.168.222.3
      name: mongo3
      user: nicorama

然后在你的角色中你可以使用 vars index, ip 等

Then in your role you can use the vars index, ip etc.
