- 参数：
- image：指定服务的镜像名称或镜像ID。如果镜像在本地不存在，Compose将会尝试拉取镜像。
- container_name：容器名称，相当于docker run --name xxx，里面的–name参数。
- build：指定Dockerfile所在文件夹的路径。Compose将会利用Dockerfile自动构建镜像，然后使用镜像启动服务容器。
- volumes：挂载一个目录或者一个已存在的数据卷容器，相当于docker run -v xxx:xxx里面的-v参数。
- environment：环境变量，相当于docker run -e xxx=xxx里面的-e参数。
- ports：映射端口，相当于docker run -p xx:xx里面的-p参数。
- restart：重启方式，相当于docker run --restart里面的–restart参数。
- command：覆盖容器启动后默认执行的命令，相当于docker run xxx /bin/bash里面最后一段命令。
- 这个 docker-compose，等于命令

- 生成镜像
docker-compose build --no-cache
- 启动docker-compose
docker-compose up -d
- 测试
使用mysql客户端，查看数据是否存在。
