Kubernetes

Preferred Kubernetes environments are Minikube, Kind and K3s. It's depends on your use case.

1. Minikube: Getting started with Fully Kubernetes environment
2. Kind: Kubernetes environment for clusters and more than a single node
3. K3s: Kubernetes environment for a low spec machine that uses fewer resources
