ansible playbook按此顺序执行:任务,角色,任务,角色,任务

Question

原谅我的新手问题,但是我想执行三个任务并在剧本中使用两个角色,顺序如下:

1. 任务
2. 角色
3. 任务
4. 角色
5. 任务

这是我到目前为止(任务,角色,任务):

---
- name: Task Role Task
  hosts: 127.0.0.1
  connection: local
  gather_facts: false

  pre_tasks:
   - name: Do this task first
     foo:

  roles:
  - role: this role second
    foo:

  post_tasks: 
   - name: Do this task third
     foo:

这是可能的,还是应该将我的任务转变为角色？

Answer 1

每个"主机:" - 块将逐个执行.因此,您可以使用多个块来强制执行所需的执行顺序:

---
- hosts: 127.0.0.1
  tasks:
   - name: Do this task first

- hosts: 127.0.0.1
  roles:
  - role: this role second

- hosts: 127.0.0.1
  tasks:
   - name: Do this task third

Answer 2

我建议您为post ans和pre任务创建角色.

你的site.yml必须是这样的:

---
- hosts: localhost
  remote_user: "{{remote_user}}"
  sudo: yes
  gather_facts: false
  roles:
    - pre
    - main_role
    - post

在roles文件夹中,您必须具有三个角色:pre,post和main_role.

---
- name: Task Role Task
  hosts: 127.0.0.1
  connection: local
  gather_facts: false

  tasks:
    - name: task1
      foo: 

    - name: include role1
      include_role: 
        name: myrole1

    - name: task2
      foo:

    - name: include role2
      include_role: 
        name: myrole2
