有没有办法允许 Docker 容器连接到主机但不连接到互联网

Question

I want to connect my container to host but not to internet ie It should be a able to connect to a non container process on host eg: localhost:5000

but not to internet

Answer 1

If you are executing calls from inside a container and you want to address your host , then you cannot use the localhost address (because that would still point to the inside of the container).

So, what you need to do, is use the 0.0.0.0 address ( 0.0.0.0:5000 in your case).
