Always use the right kubectl version for your cluster 🎛

In my company, I keep switching on multiple Kubernetes clusters depending on which project I am working on.

And to make it even more fun they don’t have all the same version (yes we still have a k8s 1.9 running).

Assorted items on a coffee table

A cache that periodically refreshes in the background is a common pattern that is used in several use cases, but how can we achieve this in Go? In this article, I will guide you through the concepts behind the implementation to help you understand how it works.


Your back end is a simple YAML file

I absolutely don’t think human/manual QA gates should be involved in between the writing of code and its being live. To avoid breaking things every time and to have an early cutoff system, you should use feature flags.

There are a lot of systems available on the market to manage…
