I already set up an Kuberentes Service example-service (“example” is a substitution of the real name of my website), and then use an Ingress and the Cert Manager to expose it to the internet. If I visit https://example.com it’s working perfectly. So the example-service should be already working fine.

And then I try to make some Pod to Service calls in order to allow us to do microservices in the following days.

So I connect to a shell in a Pod in the same namespace and run wget http://example-service.default.svc.cluster.local, but it will always timeout.

I also tried to call Pod directly instead of the Service: wget http://example-pod-0x9012j.default.svc.cluster.local times out too.

I also tried wget http://non-exist-service.default.svc.cluster.local and it returns “Name or service not known” error immediately, so it seems the DNS lookup in the previous command is working.

I go back to Minikube and try the same thing out and it works. Is there any extra work to make Pod to Service/Pod working in DigitalOcean Kubernetes?

Thanks in advance.

Just out of curiosity, do either of these two commands work:

  • Hi Nabsul,

    Thank you so much for your response! I tried this but it doesn’t work.

    But I tried to go over everything today, and find it’s a NetworkPolicy that accidentally selected the Pod and deny incoming traffic.

    Thank you anyway!
