How to make a separate private port for express in docker?

Question

Node.js

The node used for ssr vue.js uses the port 8080/tcp. You need to add a separate port, with a route, so that access is only inside docker.

Answer 1

If you mean that you need other containers to be able to access this port, then you need to link them, or you can make a shared network for them. Here it is described how to do it. This is written for docker-compose, if anything.
