golang 和docker初次搭建

https://studygolang.com/articles/12670
参考的这篇文章。踩了几个坑。
这里配上成功的流程:

1. 创建工程

mkdir helloWorldDocker
cd helloWorldDocker

2. 创建main.go文件

package main
import (
 "fmt"
 "net/http"
)
func main() {
 fmt.Println("abc")
 http.HandleFunc("/", homePage)
 http.HandleFunc("/login", login)
 _ = http.ListenAndServe(":80", nil)
}
func homePage(w http.ResponseWriter, r *http.Request) {
 fmt.Println("Hello Docker")
}
func login(w http.ResponseWriter, r *http.Request) {
 fmt.Println("Login Docker")
}

3 在helloWorldDocker下创建Dockerfile

FROM golang:latest
WORKDIR $GOPATH/src/helloWorldDocker
COPY . $GOPATH/src/helloWorldDocker
RUN go build .
EXPOSE 8080
ENTRYPOINT ["./helloWorldDocker"]

4 返回上级目录

cd ../

5 docker编译你的项目-注意docker的命名不能有大写

docker build -t hellow ./helloWorldDocker

5 docker 上运行项目

 docker run -p 8080:8080 hellow 

 abc
