How to connect with MySQL DB running as container in docker? [duplicate]

Answer 1

Your docker container should be able to bind its mysql port to any port on the VM. You do it with the -p VMPort:containerPort option of docker run.

https://docs.docker.com/engine/reference/run/#expose-incoming-ports

So this command

docker run -p 3306:3306 your-sql-container

Will publish the 3306 port of your container to the 3306 port of your VM.

At that point you should be able to hit your SQL with

Connection con = DriverManager.getConnection("jdbc:mysql://10.0.2.15:3306/databaseName","root","myrootpassword");

I used your VM address and the binded port on the VM. You should replace databaseName with the actual name of your DB.

Answer 2

You will need to put Database name there. conn = DriverManager.getConnection("jdbc:mysql://hostname:port/dbname","username", "password"); Check out this link

Also, it would not hurt to add port in your connector.
