How to create a single cluster with containerd instead of docker ?

[raphael10-collab]

Hi! I installed and setup Kubernetes Cluster using containerd ( I followed these indications: https://www.linuxtechi.com/install-kubernetes-on-ubuntu-22-04/ ) .

But now, that I want to install a single k8s cluster , it seems that I'm not able to use the script setup-kind-multicluster.sh , because it requires docker :

  root@k8s-eu-1-master:~/k8ssandra-operator# ./scripts/setup-kind-multicluster.sh --clusters 1 --kind-worker-nodes 5
  ./scripts/setup-kind-multicluster.sh: line 70: docker: command not found

I tried then to install docker, but there is a conflict between containerd and docker :

root@k8s-eu-1-master:~/k8ssandra-operator# sudo apt install docker.io

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 containerd.io : Conflicts: containerd
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
