(1). 需求
- 不想重复造轮子,因为,我要的就三个参数而已,为了这三个参数增加一个工程不划算.
- 开发或者运维工程师,可以通过Jenkins浏览(注意是:浏览,而不是手写输入)构建物,从而进行发版.
- 效果如下:
# 运维定义的发版构建物目录如下:
# 可以通过git去拿取,也可以sync同步过来.
lixin-macbook:Desktop lixin$ tree ansible_files/

└── test-service # 第一级下拉列表框

(2). Jenkins安装插件
Active Choices Plug-in这是一个构建动态参数的插件.
(3). Pipeline定义
Ansible脚本内容请参考该链接“Jenkins + Ansible 自动化部署解决方案(七)”

(6). 总结
实际上:运维需要的仅仅只是Jenkins的参数以及UI界面而已.主要是不想自己再研发一套UI界面出来,以及权限管理等等.
