Question

我收集了角色和运行这些角色的主机。但是我也有只需要其中一些角色的“自定义”主机，并且它改变了主机所需的角色。我该如何创建可针对特定主机组运行的剧本，并在每个角色之前询问是否应运行该角色？

到目前为止，我已经创建了剧本custom.yml（这不起作用...）：

- name: Select roles
  hosts: custom
  become: yes
  roles:
  - role: custom
  - { role: common, when: run_common == "Y" or run_common == "y" }
  - { role: system, when: run_system == "Y" or run_system == "y" }
  - { role: date, when: run_date == "Y" or run_date == "y" }
  - { role: swap, when: run_swap == "Y" or run_swap == "y" }
  - { role: users, when: run_users == "Y" or run_users == "y" }

我创建了一个角色来提示是否运行特定角色-custom / tasks / main.yml：

- include_tasks: select_roles.yml
  with_items:
  - common
  - system
  - date
  - swap
  - users

custom / tasks / select_roles.yml：

- include_vars:
  vars_prompt:
    - name: "run_{{ item }}"
      prompt: "Run {{ item }}?"
      default: "N"

  tasks:
    - set_fact:
        run_{{ item }}: "run_{{ item }}"
      when: "run_{{ item }}" == "Y"

目前，我将其全部运行在一个剧本中，但其中很多内容都是复制粘贴和编辑的，而且看起来很丑：

- name: Run select roles on all custom nodes
  hosts: custom
  become: yes
  vars_prompt:
     - name: "run_common"
     prompt: "Run common?"
     default: "N"
     private: no
     - name: "run_system"
     prompt: "Run system?"
     default: "N"
     private: no
     - name: "run_date"
     prompt: "Run date?"
     default: "N"
     private: no
     - name: "run_swap"
     prompt: "Run swap?"
     default: "N"
     private: no
     - name: "run_users"
     prompt: "Run users?"
     default: "N"
     private: no
  roles:
  - { role: common, when: run_common == "Y" or run_common == "y" }
  - { role: system, when: run_system == "Y" or run_system == "y" }
  - { role: date, when: run_date == "Y" or run_date == "y" }
  - { role: swap, when: run_swap == "Y" or run_swap == "y" }
  - { role: users, when: run_users == "Y" or run_users == "y" }

查找此解决方案。我觉得你会喜欢它的。您可以将var保存在另一个文件中，然后先加载它们。

---
- name: Run Specific Role
  hosts: localhost
  connection: local
  gather_facts: false

  vars:
    mymenu:
      - common
      - system
      - date
      - swap
      - users
    allowed_items:
      - "1"
      - "2"
      - "3"
      - "4"
      - "5"

  vars_prompt:
    - name: runmenu
      prompt: "Run\n1 - {{ mymenu[0] }}\n2 - {{ mymenu[1] }}\n3 - {{ mymenu[2] }}\n4 - {{ mymenu[3] }}\n5 - {{ mymenu[4] }}\n[Enter Values with Comma as Separator]"
      private: false

  pre_tasks:

    - name: Set Fact
      set_fact:
        menu{{ item  }}: "menu{{ item  }}"
      with_items: "{{ runmenu.split(',') }}"
      when: item in allowed_items

  roles:
  - role: common
    when: menu1 is defined

是否可以使用Ansible创建一个在运行每个角色之前都会提示的剧本？
