Hi!

The error means that port 5433 on the host is already in use by another process or container. Check what is using port 5433, or change the host port.

You can first run:

docker ps -a

Check if another container is already using port 5433. If so, you can stop/remove it or change the host port in your Compose file.

an other container is already on this port use

docker ps -a

to detect and delete the container
