介绍

Docker Compose通过一个单独的docker-compose.yml模板文件(YAML格式)来定义一组相关联的应用容器，帮助我们实现多个相互关联的Docker容器的快速部署。

如：springboot+mysql+nginx 如果一个个去部署他会非常的麻烦，这时候可以选择Docker Compose一键部署

文件名称：docker-compose.yml

MySQL

docker run \--name=mysql \-e MYSQL_ROOT_PASSWORD=123456 \-p 3306:3306 \-v mysql_data:/var/lib/mysql \--restart unless-stopped \-d \mysql:8.0

Nginx

docker run -d --name nginx \-v /etc/local/nginx/dist:/usr/share/nginx/html \-p 80:80 \--restart always \nginx

SpringBoot

docker run -d --name java-app -p 8080:8080 --restart=always app

如果一个个去进行部署会非常麻烦，这时候可以打包成一个Docker Compose一键部署

version: "3.8"services:mysql:image: mysqlcontainer_name: mysqlports:- "3306:3306"environment:TZ: Asia/ShanghaiMYSQL_ROOT_PASSWORD: 123volumes:- "./mysql/conf:/etc/mysql/conf.d"- "./mysql/data:/var/lib/mysql"- "./mysql/init:/docker-entrypoint-initdb.d"networks:- hm-nethmall:build: context: .dockerfile: Dockerfilecontainer_name: hmallports:- "8080:8080"networks:- hm-netdepends_on:- mysqlnginx:image: nginxcontainer_name: nginxports:- "18080:18080"- "18081:18081"volumes:- "./nginx/nginx.conf:/etc/nginx/nginx.conf"- "./nginx/html:/usr/share/nginx/html"depends_on:- hmallnetworks:- hm-net
networks:hm-net:name: hmall

创建并启动

需要在当前目录下

docker-compose up -d

查看容器的状态

docker-compose ps

停止容器

docker-compose top

删除并移除网络

docker-compose down
