I am learning Kubernetes and i run into trouble reaching an API in my local Minikube (Docker driver). I have a pod running an angluar-client which tries to reach a backend pod. The frontend Pod is exposed by a NodePort Service. The backend pod is exposed to the Cluster by a ClusterIP Service.
But when i try to reach the clusterip service from the frontend the dns transpile-svc.default.svc.cluster.local
cannot get resolved.
error message in the client
the dns should work properly. i followed this https://kubernetes.io/docs/tasks/administer-cluster/dns-debugging-resolution/ and deployed a dnsutils pod from where i can nslookup
.
winpty kubectl exec -i -t dnsutils -- nslookup transpile-svc.default
Server: 10.96.0.10
Address: 10.96.0.10#53
Name: transpile-svc.default.svc.cluster.local
Address: 10.99.196.82
This is the .yaml file for the clusterIP Service
apiVersion: v1
kind: Service
metadata:
name: transpile-svc
labels:
app: transpile
spec:
selector:
app: transpile
ports:
- port: 80
targetPort: 80
Even if i hardcode the IP into the request of the frontend i am getting an empty response. I verified, that the backend pod is working correctly and when i expose it as a NodePort i can reach the api with my browser.
What am i missing here? Im stuck with this problems for quite some time now and i dont find any solution.
