How to create a local development environment for Kubernetes?

Question

Kubernetes seems to be all about deploying containers to a cloud of clusters. What it doesn\'t seem to touch is development and staging environments (or such).

The disadvantage of using minkube is that it spawns another virtual machine over your machine. Also, with latest minikube version it minimum requires to have 2 CPU and 2GB of RAM from your system, which makes it pretty heavy If you do not have the system with enough resources.

This is the reason I switched to microk8s for development on kubernetes and I love it. microk8s supports the DNS, local-storage, dashboard, istio, ingress and many more, everything you need to test your microservices.

It is designed to be a fast and lightweight upstream Kubernetes installation isolated from your local environment. This isolation is achieved by packaging all the binaries for Kubernetes, Docker.io, iptables, and CNI in a single snap package.

A single node kubernetes cluster can be installed within a minute with a single command:

snap install microk8s --classic

Make sure your system doesn't have any docker or kubelet service running. Microk8s will install all the required services automatically.

Please have a look at the following link to enable other add ons in microk8s.
