docker compose down -v this command should stop and remove all running containers and volumes that are associated with the project defined by the Docker Compose files. The execution of this command needs to be successful to start up a new clean system. The warnings can be ignored, because if the volume does not exist, it cannot be removed.

docker ps --format "table {{.Names}}\t{{.Ports}}" -a this command lists all running containers and their mapped ports. Make sure that these ports do not conflict with the standard port mappings of the CoreMedia applications, when run on a single node.
