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
