若依(前后端分离）项目构建docker 镜像
1. 构建好ruoyi-admin.jar包，上传到服务器项目目录下
2. 创建conf目录将若依项目（Spring boot ）配置文件修改好，上传存入conf目录
注意：这里的地址不能写127.0.0.1和localhost 这两个地址是容器内部的地址，容器（ruoyi-admin.jar访问mysql、redis）之间相互访问需要 宿主机ip +映射出的端口号
修改配置文件参数，数据库ip和账号密码
修改端口号，这个修改不修改都无所谓，docker run时端口映射时修改也可以的
redis ip和端口修改
输入目录 rz 上传
退出conf 目录，在/home/ruoyi 目录下，已传统的方式java -jar 方式执行看看能不能启动成功
java -jar ruoyi-admin.jar --spring.config.location=conf/application.yml,conf/application-druid.yml
[root@mojin ruoyi]# java -jar ruoyi-admin.jar --spring.config.location=conf/application.yml,conf/application-druid.yml
Application Version: 3.8.5

3. 编写Dockerfile
FROM openjdk:8
MAINTAINER mojin
VOLUME /tmp
RUN mkdir -p /home/ruoyi/conf
ADD ruoyi-admin.jar /home/ruoyi/ruoyi-admin.jar
ADD conf /home/ruoyi/conf
EXPOSE 8025
RUN bash -c 'touch /home/ruoyi/ruoyi-admin.jar'
ENTRYPOINT ["java", "-Xms256m", "-Xmx256m", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/home/ruoyi/ruoyi-admin.jar", "--spring.config.location=/home/ruoyi/conf/application.yml,/home/ruoyi/conf/application-druid.yml"]
输入命令：vim Dockerfile，复制粘贴上面的Dockerfile信息
按Esc 按键退出编辑模式，输入Shift+: 键 输入wq 回车 保存退出 Dockerfile
4. 构件镜像 docker build -t ruoyi-admin .
命令行输入docker build -t ruoyi-admin . 注意后面的 “.” 不能少，ruoyi-admin为镜像名称，只能小写
docker build -t ruoyi-admin .
[root@mojin ruoyi]# docker build -t ruoyi-admin .

5. 运行构建好的docker 镜像
运行构建的docker镜像
-v /home/ruoyi/conf:/home/ruoyi/conf # 挂载配置文件数据卷
-v /home/ruoyi/logs:/home/ruoyi/logs # 挂载日志文件数据卷
docker run -p 8025:8025 --name=ruoyi-admin -v /home/ruoyi/conf:/home/ruoyi/conf -v /home/ruoyi/logs:/home/ruoyi/logs --restart=always --privileged=true -d ruoyi-admin
查看镜像运行日志
docker logs -f ruoyi-admin
启动成功
6. 写个shell 脚本，一键执行卸载镜像、构建镜像、运行镜像步骤
vim ruoyi_build.sh 创建脚本 复制粘贴
chmod 777 ruoyi_build.sh 给读写执行权限
ruoyi_build.sh
#!/bin/bash
echo "开始部署…………"
prot_r=8025
prot_c=8025
BASE_PATH=/home/ruoyi
#docker 镜像/容器名字或者jar名字 这里都命名为这个【必须为小写】
SERVER_NAME=ruoyi-admin
#容器id
CID=$(docker ps | grep "$SERVER_NAME" | awk '{print $1}')
#镜像idls
IID=$(docker images | grep "$SERVER_NAME" | awk '{print $3}')
echo "修改*.jar文件的权限"
chmod 777 $BASE_PATH/ruoyi-admin.jar
#echo "迁移完成"
# 构建docker镜像
if [ -n "$IID" ]; then
echo "存在$SERVER_NAME镜像，IID=$IID"
echo "停止运行中的容器：docker stop $CID"
docker stop $CID # 停止运行中的容器
echo "删除原来的容器：docker rm $CID"
docker rm $CID ##删除原来的容器
echo "删除原来的镜像：docker rmi $IID"
docker rmi $IID ## 删除原来的镜像
else
echo "不存在$SERVER_NAME镜像，开始构建镜像"
fi
# 构建镜像
echo "构建镜像"
cd $BASE_PATH
echo "docker build -t $SERVER_NAME ."
docker build -t $SERVER_NAME .
echo "$SERVER_NAME 容器创建完成"
# 运行容器
echo "$SERVER_NAME 容器开始运行：docker run -p $prot_r:$prot_c --name=$SERVER_NAME -v /home/ruoyi/conf:/home/ruoyi/conf -v /home/ruoyi/logs:/home/ruoyi/logs --restart=always --privileged=true -d $SERVER_NAME"
#docker run -d -p $prot_r:$prot_c --name $SERVER_NAME $SERVER_NAME
docker run -p $prot_r:$prot_c --name=$SERVER_NAME -v /home/ruoyi/conf:/home/ruoyi/conf -v /home/ruoyi/logs:/home/ruoyi/logs --restart=always --privileged=true -d $SERVER_NAME
echo "完成部署。"
执行 sh ruoyi_build.sh
sh ruoyi_build.sh
[root@mojin ruoyi]# sh ruoyi_build.sh
开始部署…………
修改*.jar文件的权限
存在ruoyi-admin镜像，IID=d9a5fabe40d7
停止运行中的容器：docker stop 33a7462a936d
33a7462a936d
删除原来的容器：docker rm 33a7462a936d
33a7462a936d
删除原来的镜像：docker rmi d9a5fabe40d7
