The docker-compose.yml has ‘command’ property that shows how to start the app ( could be function called in package.json ). The default port for debugging is 9229 and will be in the docker-compose.yml file or append -p 9229:9229 to the docker-run command, example:

docker run -d -p 80:3000 -p 9229:9229 node:15.0.1-alpine
