Prerequisites

• Kubernetes cluster (Minikube or cloud provider)
• kubectl configured to access your cluster

#Troubleshooting

kubectl get pods -n webapp-namespace

kubectl logs -n webapp-namespace

kubectl get svc -n webapp-namespace

kubectl get pv,pvc -n webapp-namespace

#clean kubectl delete namespace webapp-namespace

minikube service django-service --url -n webapp-namespace

kubectl exec -it postgres-0 -n webapp-namespace -- psql -U myuser -d mydatabase
