CiliumUnreachableHealthEndpoints

Description: Indicates that a Kubernetes Node (Cilium-Pod) is not healthy or reachable from other nodes. Cause: Often duplicate podCIDRs. Solution: Please contact Natron Support as this requires administrative intervention on the node level.

Namespace Stuck in Terminating

Find blocking resources:

kubectl api-resources -o name --verbs=list --namespaced | xargs -n 1 kubectl get --show-kind --ignore-not-found -n $NAMESPACE

If needed, remove finalizers manually via kubectl proxy and curl.

Network related issues

When you experience network related issues that only occur within your cluster, it is most likely a Cilium issue. You can check if Cilium is blocking traffic by accessing Hubble and check for denied connections.
