Unable to create a cluster in GKE

danmatulescu · January 10, 2024, 2:12pm

Hello,

I am trying to install k8ssandra in a GKE cluster, version 1.26.6.
The environment I have doesn’t have access to the helm repo or docker hub, so what I did was to pull all the required images into the private registry and locally downloaded all the required helm charts for k8ssandra-operator v1.11

Operator pods are starting fine:

k8ssandra-operator-7c49d4796d-rh4r7 1/1 Running 0 175m
k8ssandra-operator-cass-operator-c79846f7-dtc4q 1/1 Running 0 175m

Now, when I try to create a demo cluster, I get the below error:

Error from server (InternalError): error when creating “…/k8ssandra-demo.yaml”: Internal error occurred: failed calling webhook “vk8ssandracluster.kb.io”: failed to call webhook: Post “https://k8ssandra-operator-webhook-service.k8ssandra-operator.svc:443/validate-k8ssandra-io-v1alpha1-k8ssandracluster?timeout=10s”: context deadline exceeded

Can you please advise on what may be missing?

Thanks,
Dan

Dan - I have exact same issue. We are able to deploy same configuration in Azure AKS, but we get the same error message in our GCP GKE environment

Hi,

it looks like the validation webhook isn’t responding within due time, which could be related to firewall rules or networking in place.
I see in the initial post that istio is running in the cluster, which may have an impact here.
Also check that the webhook is running and responsive by trying to reach it directly using curl. Check the logs of the k8ssandra-operator pod to see if there’s any problem reported there.

Rest assured that k8ssandra-operator works fine in GKE, this is where we test it most of the time.

Dan - is your GKE cluster setup as private? There seem to be some general issues with some webhooks and private GKE clusters

markhley · January 26, 2024, 10:12pm

Dan - issue is definitely regarding GCP GKE private cluster and I have solution. By default, the private GKE cluster has firewall rules to enable 443, but the target port for the K8ssandra webhook is 9443. You have to add firewall rule to account for this to allow access to control plane. Here is article that talks about this and steps to add the firewall rule - Creating a private cluster | Google Kubernetes Engine (GKE) | Google Cloud - My cluster is building now. Let me know if this works for you

Thanks @markhley. It helped me.

Hello @markhley, in my case I didn’t see those errors in the k8ssandra-operator log.
@alexander I suspect the issue on my side is somewhere else, I have istio and other addons running on the cluster. Webhooks are running and responding to curl. I was able to overcome the issue by removing the ValidatingWebhookConfiguration.
