Initializing a fresh instance When a container is started for the first time it will execute files with extensions .sh and .js that are found in /docker-entrypoint-initdb.d. Files will be executed in alphabetical order. .js files will be executed by mongo using the database specified by the MONGO_INITDB_DATABASE variable, if it is present, or test otherwise. You may also switch databases within the .js script.

nodejs - docker image https://hub.docker.com/_/node/

As we can see, the command defined in in the docker-compose.yml file overrides the one defined in the Dockerfile. // Command instruction in the Dockerfile CMD [“node”, “server.js”] // Command instruction in the docker-compose.yml file command: nodemon server.js
