The same for the files you place in /docker-entrypoint-initdb.d. We added a new user, john, which is set as a default user for all the containers running using that Docker image. We'll use the docker exec command to access it: docker exec -it baeldung bash Pay attention to the Dockerfile that we created earlier.

You'll be able to connect using port 3306 on the MySQL container's hostname (this matches the service name defined in your Compose file).You could change it from a running container, using a docker exec session, as described in " Connecting to MySQL Server from within the Container" When a container is started for the first time, a new database with the specified name will be created and initialized with the provided configuration variables. Both containers will exist in the same Docker network.

Define another service for the new container. If you need to connect from another Docker container, it's best to use Docker Compose. You'll now be able to connect to localhost:33060 using MySQL clients running on your host. If you're not using Docker Compose, pass -p 33060:3306 to docker run when you start your container. This will bind port 33060 on your host machine to the container's port 3306. Add the following to your docker-compose.yml file, within the mysql service definition: ports: I created it in the same level as the docker-compose.yml inside a folder secrets named dbpassword.txt and dbrootpassword.txt (commit at this point) and then add the passwords inside them. Bind a host port to the container's port 3306. To use Docker Secrets, we need to create two files (for two passwords). You must setup a port binding if you want to access MySQL from your host.
