Running a drupal site using Minikube - kubernetes

Question

I'm learning how to use Kubernetes by using Minikube and creating a Drupal site.
I was able to minikube service my drupal site and reach up to the "Set up Database" page and that's about it. It keeps telling me I need to insert the correct info. I checked my MYSQL pod and was able to exec and MySQL into my database.
I'm not sure what I'm missing? Is MYSQL pod not connected to my Drupal pod?
Here's my drupal-mysql.yaml file:
---
apiVersion: v1
kind: Service
metadata:
name: drupal-mysql-service
spec:
ports:
- name: mysql
port: 3306
targetPort: 3306

You need to connect between containers using IP address of containers or may be pods, but what is point of getting database in container, instead install mysql in host machine I have done it, checkout the guide
