#multinode #kubernetes #10mins

If you are using Minikube and want to have a cluster with multiple nodes but worried it will take days to set up one?. Let me show you how to do this in just 10 mins.
This cluster can be used for your local development and testing, also learning all Kubernetes features.
I am going to use Multipass and K3S to set up this cluster.

This will bring up each node of the cluster as a separate Ubuntu VM.

I have also shown in the past how to use KIND to setup similar multinode cluster but it was using docker container for nodes, refer below
