准备工作
我这里直接在 K8S 开发集群中部署相关实例。
生产求稳，建议大家还是买云数据库服务。
部署 Mysql、Redis、Etcd。
部署 Drone、Drone-Runner-Kube
开始探索
准备 DevOps 部署相关配置

验证
我这里已经部署好了一个开发测试的 Pod 实例，大家可以试用。
shorten api 调用
# curl -i "https://shorturl.your-domain.com/shorten?url=https://www.your-domain.com"curl -i "https://shorturl.hacker-linner.com/shorten?url=https://www.hacker-linner.com"复制代码
expand api 调用
# curl -i "https://shorturl.your-domain.com/expand?shorten=6d11a1"curl -i "https://shorturl.hacker-linner.com/expand?shorten=6d11a1"复制代码
利用工具查看 Redis 与 Etcd 中的键值对
