Hey All,
I’m having some specific issues with various pods (running dgraph on kubernetes) not connecting after a fair amount of use which I outlined here Pod connection issues · Issue #2818 · dgraph-io/dgraph · GitHub. I was also wondering if there are any good general strategies for debugging (what appear to be) consensus issues - all I’ve been able to do is treat each node as a black box, and try to turn things on and off again.
Cheers.
We usually use LoadBalancer, you are using NodePort. There must be differences there. Check dgraph/contrib/config/kubernetes at master · dgraph-io/dgraph · GitHub
A NodePort service is the most primitive way to get external traffic directly to your service. NodePort, as the name implies, opens a specific port on all the Nodes (the VMs), and any traffic that is sent to this port is forwarded to the service.
Source: Kubernetes NodePort vs LoadBalancer vs Ingress? When should I use what?
So I guess the K8’s DNS works differently tho.
Great, thanks for the feedback. We’re working on debugging that now (it takes a while to recreate the issue). Are multi node clusters generally stable now? Earlier this year there were several connection errors and we were recommended to use single node clusters.
