我有一个springboot应用程序访问我的localhost：5432 postgress数据库
我已将它停靠并希望从docker容器连接到数据库
像这样运行容器
docker run -p 8080:8080 risk-assesment:v1
我收到以下错误

答案 0 :(得分：0)
如果您使用的是mac而不是localhost：5432使用此功能从docker容器内部连接到您的计算机。
docker.for.mac.localhost:5432
如果这不起作用
进入泊坞窗容器
docker exec -it yourcontainername /bin/bash
获取主机IP地址
netstat -nr | grep '^0\.0\.0\.0' | awk '{print $2}'
在springboot aplication中使用此ip而不是localhost。
