关于asaffold是个什么玩意以及安装，请自行百度；详细用法：https://skaffold.dev/docs/。
这里用一个简单的go程序做测试其功能，主要的文件如下：
main.go
package main
import (
"io"
"net/http"
)
func main() {
http.HandleFunc("/", helloWorldHandler)
http.ListenAndServe(":8800", nil)
}
func helloWorldHandler(w http.ResponseWriter, r *http.Request) {
io.WriteString(w, "Hello world! ,and from akaffold v1")
}
app.yaml

开始测试
skaffold run

通过nginx访问
[图片上传中...(image.png-f91f4c-1552897853420-0)]
更改main.go文件，将v1改为v2
skaffold run
再次通过nginx访问

顺利实现想象中的逻辑，skaffold的强大功能远不如此，值得深入研究；然后我越来越觉着这货的逻辑很像一个工具：circleci.
