By following this post you can easily create a Single-node Kubernetes Cluster using kubeadm on Ubuntu 20.04. Although it is more difficult to create a cluster with kubeadm, with its configuration options you can tweak the cluster to your needs. There are many tools out there to provision single-node Kubernetes clusters but kubeadm is the way to go for a production-like set-up.
