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
CGO_ENABLED=0 go install
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
