docker中使用golang:alpine镜像制作开启goweb的dockerfile
package main
import(
"net/http"
"fmt"
)
func main(){
fmt.Println("开启后端")
http.HandleFunc("/Hello",PrintHello)
err:=http.ListenAndServe(":8080",nil)
if err==nil{
fmt.Println("开启8080端口")
}
}
func PrintHello(w http.ResponseWriter, r *http.Request){
if r.Method!="GET"{
return
}
fmt.Fprint(w,"hello world")
}
from golang:alpine
workdir /app
copy . /app/
# run go build main.go
# expose 8080
# entrypoint ["./main"]
expose 8080
entrypoint go run main.go
- 感悟
- run和entrypoint,都可以执行命令,可以不用写中括号
