容器项目之前后端分离

容器化部署ruoyi项目

#需要的镜像nginx、java、mysql、redis、
#导入maven镜像、Java镜像和node镜像
docker load -i java-8u111-jdk.tar
docker load -i maven-3.8.8-sapmachine-11.tar
docker load -i node-18.20.3-alpine3.20.tar
#拉取MySQL和nginx镜像
docker pull mysql:5.7
docker pull nginx:1.16.1
#准备数据库
docker run -itd --name ruoyi-mysql -v ./sql:/docker-entrypoint-initdb.d -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=ry-vue mysql:5.7 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
#准备redis
docker run -itd --name ruoyi-redis
#获取ruoyi的源码包
git clone https://gitee.com/y_project/RuoYi-Vue.git && cd RuoYi-Vue
#修改后端的代码
vim /opt/RuoYi-Vue/ruoyi-admin/src/main/resources/application.yml

vim /opt/RuoYi-Vue/ruoyi-admin/src/main/resources/application-druid.yml

#打包后端代码
docker run -it --rm -v .:/opt/app -v /root/.m2:/root/.m2 -w /opt/app maven:3.8.8-sapmachine-11 mvn package
#打包前端代码
cd 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"
#打包好的的代码
java ： ruoyi-admin/target
前端 ： ruoyi-ui/dist
