I’ve been told my k8ssandra people that the following errors are related to kubernetes
What do I have to do to detect, and solve, the issue?
kind seems working fine:
root@k8s-eu-1-master:~# kind create cluster
Creating cluster "kind" ...
✓ Ensuring node image (kindest/node:v1.27.3) 🖼
✓ Preparing nodes 📦
✓ Writing configuration 📜
✓ Starting control-plane 🕹️
✓ Installing CNI 🔌
✓ Installing StorageClass 💾
Set kubectl context to "kind-kind"
You can now use your cluster with:
kubectl cluster-info --context kind-kind
root@k8s-eu-1-master:~# kubectl cluster-info --context kind-kind
Kubernetes control plane is running at https://127.0.0.1:41237

root@k8s-eu-1-master:~# kind get clusters
kind
