And for the Minikube cluster here's the setup to do it:
# Start the application first to deploy the Laravel and the MySQL
helm install <application-name> .
# First we need to check the IP for both pods, which that is the webapp and the database server
kubectl get pods
kubectl describe pod <laravel-pod-name>
kubectl describe pod <laravel-pod-mysql-db>
# After that we execute inside the pod of Laravel Application
kubectl exec -it <laravel-pod-name> bash
# Fill out the environment of the .env Laravel application with this value
APP_NAME=Laravel
APP_ENV=local
APP_KEY=<laravel-app-key> # We need to generate this manually with php artisan key:generate
APP_DEBUG=true
APP_URL=http://localhost/login
DB_CONNECTION=mysql
DB_HOST=<ip-of-laravel-mysql-db-pod>
DB_PORT=<pod-port>
DB_DATABASE=<db-name>
DB_USERNAME=<db-username>
DB_PASSWORD=<db-password>
# After we change the value we do this inside the pod
php artisan migrate
# After that we try to access the pod of Laravel application
kubectl port-forward <laravel-app-pod> 80 8000
# Access the application with
http://localhost:8000
# Add Helm Repositories
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo add grafana https://grafana.github.io/helm-charts
helm repo update
# Install Prometheus
helm install prometheus prometheus-community/prometheus
# Install Grafana
helm install grafana grafana/grafana
The database will start the service itself
