How to change port number?

[mrmaglet]

I can't change the port.
I'm running featmap as docker compose on win11 with WLS2.

Ignoring the .env for now, I've updated the docker-compose.yml to

                ports:
                        - 6000:5000

I've used Gemini to trouble shoot. It suggest the go application is using IP6 inside the container.

// Gemini dialog 

CONTAINER_ID=$(sudo docker ps -aqf "name=featmap-featmap-1")
sudo docker exec -it $CONTAINER_ID sh -c "apk add net-tools >/dev/null 2>&1; netstat -tulnp"

Output: tcp6       0      0 :::5000                 :::*                    LISTEN      1/./featmap

This output will tell us definitively if the 0.0.0.0: change in main.go has taken effect, or if the featmap application is still only binding to IPv6 (:::5000). This is the key to understanding why your site is unreachable.

Not sure how to proceed.
