构建最小的docker容器
黄尚 · 2016-03-25 · via 博客园 - 黄尚

创建一个最小的基本镜像:

tar cv --files-from /dev/null | sudo docker import - skycn/base

 建一个hello.go:

package main

import (
	"fmt"
	"net/http"
)

func helloHandler(w http.ResponseWriter, r *http.Request) {
	fmt.Fprintln(w, "Hello World from Go in docker")
}

func main() {
	http.HandleFunc("/", helloHandler)

	fmt.Println("Started, serving at 8080")
	err := http.ListenAndServe(":8080", nil)
	if err != nil {
		panic("ListenAndServe: " + err.Error())
	}
}

编译hello.go

建一个Dockerfile

FROM skycn/base:latest
COPY hello /
CMD ["/hello"]

编译Dockerfile

docker build -t skycn/hello-go .

运行hello-go

docker run -it -p 8080:8080 skycn/hello-go

发布docker image

docker push skycn/hello-go
