Starting Kubernetes v1.20, Kubernetes deprecated docker as a runtime and used containerd instead. Follow the instructions to install and configure containerd on your system.
Follow the Ubuntu/CentOS instructions to setup a Kubernetes cluster. For full features, please install Kubernetes v1.21 or later.
You can run the sample by setting up a single-node Kubernetes cluster:
kubectl taint node --all node-role.kubernetes.io/master-
kubectl taint node --all node-role.kubernetes.io/control-plane- # >= v1.20
