ansible-2.x - Ansible 角色 : What content should I wtrite in `site.yml` and `webservers.yml` ?

Question

文档中有一个角色目录结构示例( http://docs.ansible.com/ansible/latest/playbooks_reuse_roles.html#role-directory-structure )

Example project structure:

site.yml
webservers.yml
fooservers.yml
roles/
   common/
     tasks/
     handlers/
     files/
     templates/
     vars/
     defaults/
     meta/
   webservers/
     tasks/
     defaults/
     meta/

问题:
我应该写什么内容 site.yml和 webservers.yml ?

例如:

文档说( http://docs.ansible.com/ansible/latest/playbooks_reuse_roles.html#using-roles )，

The classic (original) way to use roles is via the roles: option for a given play:

---

- hosts: webservers
  roles:
     - common
     - webservers

上面的内容可以放在哪个文件里？

根据文档示例，您将拥有:

网络服务器.yml:

- hosts: webservers
  roles:
     - common
     - webservers

fooservers.yml:

- hosts: fooservers
  roles:
     - common
  tasks:
     - shell: /usr/bin/foo.sh

站点.yml:

- include: webservers.yml
- include: fooservers.yml
