单体部署⑤——后端部署
# 单体部署⑤——后端部署
# 前言
下载本项目，进入到当前文件夹执行打包命令
git clone https://gitee.com/himitzh0730/hoj-deploy.git && cd hoj-deploy/src/backend
1
当前文件夹为打包hoj-backend镜像的相关文件，将这些文件复制到同一个文件夹内，然后打包DataBackup (opens new window)（SpringBoot项目）成jar包也放到当前文件夹，之后执行以下命令进行打包成镜像
docker build -t hoj-backend .
1
项目依赖于hoj-redis，hoj-nacos，hoj-mysql等镜像成功启动，以及根据前面三个镜像的配置修改环境参数才可正常启动
docker-compose 启动

用于检测nacos是否启动完成，然后再执行启动backend

if [[ $CODE -eq 200 ]]; then
# 输出绿色文字，并跳出循环
echo -e "\033[42;34m nacos is ok \033[0m"
break
else
# 暂停1秒
