Cannot make Pod to Service/Pod call in Kubernetes
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.
