I want to start a minikube cluster with a data base and a java backend.

I have a persistent volume and the service for the mariadb database with the following persistent, claim and delpoyment

• MariaDBpasteBin

and the java backend with the deployment and service

• javaPastebin

in addition my java backend uses dropwizard and I specify the database address and all the credentials in a config.yml

logging:
  level: INFO
  loggers:
    DropwizardBackend.org: DEBUG
dataBase:
  driverClass: org.mariadb.jdbc.Driver
  user: <userName>
  password: <password>
  url: jdbc:mariadb://<database address>:<port>/<database Name>

Since my java backend needs to connect to the database to run at the moment I get a error message since the specified data base can not be found. I was wondering what the address of the database is? Do I have to specify it like the external IP of the java-deployment? How ever I prefer if only the backend is able to access the database.
