#Troubleshooting

kubectl get pods -n webapp-namespace

kubectl logs <pod-name> -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
