VSHN.timer #99: kubectl learn all

Welcome to another VSHN.timer! Every Monday, 5 links related to Kubernetes, OpenShift, CI / CD, and DevOps; all stuff coming out of our own chat system, making us think, laugh, or simply work better.

This week we’re going to talk about useful online resources to learn all you need to know about Kubernetes.

1. Years have passed since Kelsey Hightower published his epic “Kubernetes the Hard Way” tutorial, and many alternatives have appeared ever since. One of the latest is Kubernetes by Example, with separate pages explaining each Kubernetes concept (pods, services, etc) as well as full learning paths to prepare you for certification.

2. LearnK8s.io remains one of the best resources for Kubernetes-related content out there. One of its latest gems is this explanation about how to select the best autoscaling strategy: horizontal? Vertical? Cluster? And what if they fail?

3. How do you deploy your apps? With manifests? Helm charts? Kustomize? Ketch? Kapp? Flux? Argo CD? Keptn? If you are as confused as us, you might want to check the Podtato Head project, and see by yourself all and each one of these options in action.

4. Do you actually need Kubernetes? The answer will not surprise you. (And as one VSHNeer remarked internally, the question is rather, do people actually spend money domains for this kind of websites?)

5. Remember The Illustrated Children’s Guide to Kubernetes? In the same spirit, here’s “Gently Down the Stream”, an illustrated gentle introduction to Kafka. We need more of these; they bring a sense of humanity to all of this bit pushing thing we do day after day.

My 2-year-old daughter's favorite stuffed animal, "Meow-Meow," is a critical service in my house, so I run a highly available three-node Meow-Meow cluster.

Here's how it works:
