如果要在容器内连宿主机上的服务，宿主机的127.0.0.1并不是容器内的127.0.0.1。 要实现这种有两种方式，

一是使用host网络模式

docker run --network host --env db_type=REDIS --env db_host=127.0.0.1 --env db_port=6379  -p 5010:5010 jhao104/proxy_pool

二是使用host.docker.internal：

docker run  --env db_type=REDIS --env db_host=host.docker.internal --env db_port=6379  -p 5010:5010 jhao104/proxy_pool

我也是一样的错误，群辉Docker

docker run --net=host --env DB_CONN=redis://:@host.docker.internal:6379/0 -p 5010:5010 jhao104/proxy_pool:latest
