How to deploy new Docker images to your Kubernetes cluster?

This is the first step of my intention to write a series of articles where I would explain some common patterns used in Golang.

Few months ago I wrote an article about replacing Minikube with MicroK8s , but now we have even better soluion, kind .

Official Golang documentation contains just tar.gz package to be downloaded and installed on Ubuntu Linux, but this is not quite comfortable way because Golang won’t be automatically updated after new release.

Modern Linux desktop distributions contain really powerful settings possibilities, but it is very often difficult to find out how to configure something.
