Launching a multi-node Kubernetes cluster with Kind
In this section, we are going to discuss another tool called Kind, which is far less known than Minikube, but which resembles it a lot. This tool is also designed to run a Kubernetes cluster locally just like Minikube. The main difference is that Kind is capable of launching multi-node Kubernetes clusters contrary to Minikube, which is a single-node solution.
The whole idea behind Kind is to use Docker containers such as Kubernetes worker nodes thanks to the Docker-in-Docker (DIND) model. By launching Docker containers, which themselves contain the Docker daemon and the Kubelet, you can manage to make them behave as Kubernetes worker nodes.
This is exactly the same as when you use the Docker driver for Minikube, except that there, it will not be done in a single container but in several. The result is a local multi-node cluster. Similar to Minikube, Kind is free, and you don't have to pay to use it.
