How Kubernetes secrets work is one of the most asked questions from people learning Kubernetes, according to Google.

So join me on this thread as I break it down for you.

The 5 things I’ve done in my career that have had the biggest reward:

1. Learn another programming language.

You don’t need to learn and write in a dozen languages, but ensuring you learn and work with at least one other is invaluable. 2. Share what you learn

2. Your KUBECONFIG has the wrong URL for the API server
3. Your static manifests, /etc/kubernetes/manifests, need fixed.
