Docker Compose 实现 Nginx 与 MySQL 多容器服务编排

热爱Liunx的丘丘人2026-05-29 12:12

（一）编写 docker-compose.yml

vim docker-compose.yml

复制代码

version: '3'

services:     
  nginx:

    image: nginx:latest       

    container_name: my-nginx

    ports:

       - "8080:80"     

    volumes:

       - ./html:/usr/share/nginx/html    

    depends_on:   

       - mysql



  mysql:

    image: uhub.service.ucloud.cn/library/mysql:5.5.46

    container_name: my-mysql

    ports:

       - "3306:3306"

    environment:

       MYSQL_ROOT_PASSWORD: 123456

    volumes:

       - mysql-data:/var/lib/mysql 



volumes:

  mysql-data:

（二）运行多容器

$root@Client compose-demo$ # docker compose up -d

WARN $0000$ /root/compose-demo/docker-compose.yml: the attribute `version` is obsolete, it will be ignored, please remove it to avoid potential confusion

$+$ up 2/2

✔ Container my-nginx Started 0.5s

✔ Container my-mysql Started

（三）测试Nginx

（四）测试mysql

（五）查看 Docker 自动创建的网络

（六）验证容器间通信

（1）进入容器内，安装ping。

apt update

apt install -y iputils-ping

（2）ping mysql

root@2fe955aa5b11:/# ping mysql

PING mysql (172.18.0.2) 56(84) bytes of data.

64 bytes from my-mysql.compose-demo_default (172.18.0.2): icmp_seq=1 ttl=64 time=0.079 ms

64 bytes from my-mysql.compose-demo_default (172.18.0.2): icmp_seq=2 ttl=64 time=0.072 ms

（七）停止服务

$root@Client compose-demo$ # docker compose up -d
