TCS-iOn-Rio

A basic spring boot REST web application served with tomcat that lets you store users and fetches all the stored users using mysql database.

  Fill the env with the appropriate values
• make db_files
  This is the dir where mysql data is persisted.
• make start
  This will start the webserver on port 8080 by running a docker-compose which spins up a mysql db which reads the envs from the .env.

• stop removes the docker-compose containers and networks
