• 提交github
  实际上很简单，主要提交到github 就可以了，参考https://github.com/rongfengliang/ship-k8s-demo

使用ship 部署

• init

ship init github.com/rongfengliang/ship-k8s-demo

从下图可以看出，会自动进行项目类型的判断，还是很方便的，之后会提示是否使用ui工具，进行配置
效果

• UI 配置（生成kustomize&&部署文件）
  
  
  
  上边的确认之后，会自动退出UI
• 生成的文件
  
• 部署
  参考ui的说明就可以了

kubectl apply -f rendered.yaml

• 变更捕获&&更新
  修改github，查看变更信息

ship watch && ship update

修改镜像为openresty
