It's not clear where is deployment?!

Why the table is not getting created automatically. As you are using hibernate ORM

Thanks for the demo, Why we need 3307 port linked to 3306 mysql port, what is the use of specifying a different port of 3307?
Similarly the port given in the compose file 8082 and the local host is connected with 8080, why we need to have a different port in compose file

Thanks so much!
I didn't know that I have to set the enviornment-variables defining the connection. I thought the app would have gotten them from the application.properties. 👍👍👍👍
