docker compose完成简单项目部署

1. 项目环境

centos7 + docker + mysql + redis + ruoyi项目

ruoyi项目链接：https://gitee.com/y_project/RuoYi-Vue.git

2. 进行项目前后端代码打包

后端打包：

修改mysql连接的相关配置文件 RuoYi-Vue/ruoyi-admin/src/main/resources/application-druid.yml

修改redis连接的相关配置文件 RuoYi-Vue/ruoyi-admin/src/main/resources/application.yml

使用maven打包(这里使用容器目录挂载方式进行打包)

cd RuoYi-Vue
docker run -it --rm -v .:/opt/app -v /root/.m2:/root/.m2 -w /opt/app maven:3.8.8-sapmachine-11 mvn package

前端打包：

使用node打包(这里使用容器目录挂载方式进行打包)

cd ruoyi-uicd ruoyi-ui
docker run -it --rm -v .:/opt/app -w /opt/app node:18.20.3-alpine3.20 /bin/sh -c "npm install  --registry http://registry.npmmirror.com && npm run build:prod"

3. docker compose来构建服务

目录层级如下

将打包好的jar包放在java目录下用于构建镜像

将打包好的dist前端代码放到nginx中来构建镜像

sql目录用于存放用于导入的sql数据

database进行mysql数据目录的映射

./java/

dockerfile

FROM java:8u111-jdk
COPY . /opt/app
WORKDIR /opt/app
COPY start.sh /
CMD sh /start.sh

java.sh

sleep 10java -jar ruoyi-admin.jar

等待10秒是因为Java构建镜像需要关联mysql，需等待mysql镜像构建完成

./nginx/

nginx.conf
