ansible 实例笔记3: 部署程式

在安装 docker 之前，有一些套件是必需要用到，使用 ansible 统一部署安装：目前个人觉得可程式化部署最方便
增加以下变数清单:
其实一般照原则是要统一放在 vars.yml，为了能让大家更了解直接写在全域变数较容易理解

vars:  requried_packages:    - apt-transport-https    - ca-certificates    - curl    - gnupg-agent    - software-properties-common  

主程式说明:
部署程式跟之前的差别如下:
1.增加 list vars
2.利用项目迴圈安装

- hosts: web7  name: play-test  gather_facts: no  become: yes  vars:    ansible_become: yes     ansible_become_method: sudo    ansible_become_pass: docker    requried_packages:      - apt-transport-https      - ca-certificates      - curl      - gnupg-agent      - software-properties-common    tasks:    - name: Install required packages      apt:        name: "{{ item }}"        state: latest        update_cache: true      loop: "{{ requried_packages }}"     

执行以下程式:

ansible-playbook -i inventory.ini playbook6.yml

成功画面如下:
