使用网络方式使容器互联

数据库使用两个别名 db mysql

docker network create -d bridge my-bridge-network # 创建一个网络
docker run -itd --name mariadb --env MYSQL_ROOT_PASSWORD=example \
--network=my-bridge-network --network-alias=db --network-alias=mysql mariadb # 启动数据库

docker run -itd --name MyWordPress --network=my-bridge-network --network-alias=lap -p 80:80 wordpress # 启动应用

直接使用命令 --link

docker run --name db --env MYSQL_ROOT_PASSWORD=example -d mariadb 启动数据
docker run --name MyWordPress --link db:mysql -p : -d wordpress 启动 LAP
