以下是一个简单的试用

环境准备

• 项目
  简单golang demo

go get github.com/gin-gonic/gin

main.go

package main

func main() {

    r := gin.Default()

    r.GET("/", func(context *gin.Context) {

        context.String(200, "ok")

    })

    r.Run(":8080")

}

Dockerfile

FROM golang:1.13-alpine AS build-env

WORKDIR /go/src/app

RUN  /bin/sed -i 's,http://dl-cdn.alpinelinux.org,https://mirrors.aliyun.com,g' /etc/apk/repositories

​

ENV  GO111MODULE=on

ENV  GOPROXY=https://goproxy.cn

COPY . .

RUN apk update && apk add git \

    && go build -o rest-api

​

FROM alpine:latest

WORKDIR /app

RUN  /bin/sed -i 's,http://dl-cdn.alpinelinux.org,https://mirrors.aliyun.com,g' /etc/apk/repositories

RUN apk update && apk add ca-certificates && rm -rf /var/cache/apk/*

COPY --from=ochinchina/supervisord:latest /usr/local/bin/supervisord /usr/local/bin/supervisord

COPY --from=build-env /go/src/app/rest-api /app/rest-api

COPY supervisor.conf /etc/supervisord.conf

EXPOSE 8080

CMD ["/usr/local/bin/supervisord"]

• docker-compose 文件

version: "3"

services: 

   api: 

     build: ./

     image: dalongrong/golang-supervisord

     ports: 

     - "8080:8080"
