12.docker-compose II -- demo

分享docker-compose.yml编写案例，通过docker-compose 单host部署 springboot + mysql + redis。

springboot镜像是根据：项目通过maven插件生成docker image, 当jenkins构建完成后，执行shell脚本，把docker image push 到 private registry. 获得的。

docker-compose.yml文件

version: '3.3'

services:
    redis:
        container_name: myredis
        image: redis:6.0

        networks:
            - backend
        restart: always

    mysql:
        container_name: mymysql  #应用里面用mymysql就可以连接数据库了
        image: mysql:5.6

1.通过环境变量激活对应的配置springboot配置文件，环境变量在docker-compse.yml中配置；

2.application-test.yml中引用的数据库地址是docker-compose中指定的容器名称，通过docker的网络可以连接上。
