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
CoreDNS is running at https://127.0.0.1:41237/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy


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

But I'm getting these errors :

root@k8s-eu-1-master:~/go/bin/k8ssandra-operator# scripts/setup-kind-multicluster.sh --clusters 1 --kind-worker-nodes 5
Creating 1 clusters...

This is the complete log: https://drive.google.com/file/d/1t0LAX5TtunnNYLbCVXeQ1x1pBIIL9dxv/view?usp=sharing

This is the ouput of cluster-info dump :

What should I do in order to detect and solve the root cause of the problem?

Is there another instance and or other software running on that node?

E1031 10:25:03.813191  567933 server.go:179] "Failed to listen and serve" err="listen tcp 0.0.0.0:10250: bind: address already in use"

There are some ports that are already in use, so the installation fails.

Since you are using --kind-worker-nodes 5 - it is likely the case, that fixed published ports are issuing this.
