I can’t use port forward because I can’t change the listening default port from the application inside the container.
For example if I use port forward : -p 19100:9100 for my couchbase container on both docker server… The 2nd server will try to reach on server 1 on port 9100 
because there is no option to override the default configuration inside the container.
So I need to find a solution with docker to avoid port conflict between the container and the application locally hosted on the server (both are using port 9100). idk if there is a solution from docker ?
