按照步骤构建镜像，启动报错了，本地start可以起来

你好，很高兴你对我们的产品感兴趣。通过描述，我理解你是本地打得镜像直接 docker run 启动的镜像。

前端的应用，是通过 node 代理的形式去链接后端接口，这里的后端接口是通过跑起来镜像时注入的环境变量。所以会报拿不到环境变量的错误

推荐你使用我们的一键部署代码来启动应用

helm install klever-web $CWD/klever-web/manifests/klever-web
--namespace=kleveross-system
--set service.nodePort=$KLEVER_WEB_PORT
--set model.registry.address=http://$MASTER_IP:$KLEVER_MODEL_REGISTRY_PORT

脚本启动会自动注入环境变量并启动需要依赖的后端服务
