docker-compose搭建golang本地开发环境

目前仅使用到mysql，golang， redis

目录结构 root@suniceman:~/code/docker/compose-golang$ tree . ├── docker-compose.yml └── golang └── Dockerfile

    version: "3"
    services:
      golang:
        build: ./golang
        ports:
          - "8088:8088"
        links:
          - "mysql"
          - "redis"
        volumes:

        volumes:

      redis:

注意，上述代码中： 1. golang容器下 tty: true 必须 否则在执行docker-compose up -d时 golang容器将退出

1. golang容器下 volumes 是把本地所有的源码都映射到容器中。仅在本地开发时使用，上线部署时不可。

1. golang Dockerfile

    FROM golang
    RUN apt-get update && apt-get install -y vim
    WORKDIR $GOPATH/src
    EXPOSE 8088
   

2. 构建容器

   1
    docker-compose up -d
   

3. 查看所有容器

4. 进入golang容器

    ☁  compose-golang   docker exec -it composegolang_golang_1 bash
    root@71ae8893978a:/go/src# 
   

更新dockerfile或者docker-compose.yml文件后 在docker-compose.yml 同路径下执行 docker-compose down 然后再执行 docker-compose up -d
