VSHN.timer #38: Moar Learning!

Welcome to another VSHN.timer! Every week, 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 review some learning resources online; maybe we can turn this crisis around as an opportunity to learn something new?
1. If you are reading this blog post, chances are there’s a Kubernetes cluster near you, innit? Well in that case you’ll find the Kubernetes Built-in Controls Workshop exercises very useful. Hands-on training to learn how to secure your clusters, applying the best possible settings to your infrastructure. Of course, if Kubernetes isn’t (yet) your cup of tea, try the Illustrated Children’s Guide To Kubernetes first. That will help you getting started for sure.

2. Readers of VSHN.timer know how much we VSHNeers enjoy playing with our Raspberry Pi computers (and other similar SBCs.) Here’s a nice walk-through by Alex Ellis to get a Kubernetes cluster in your Raspberry Pi in 15 minutes. But if you’ve already been there, done that, then meet the four-slot Raspberry Pi cluster board, with a starting price of USD 80. Have fun building your own household-scale cloud service!

3. Security is a complex topic, and more important than ever. Enter Cryptohack, an online platform to learn cryptography: learn protocols and algorithms, solve challenges, and earn points! A fun way to learn more about this crucial subject. Also worth mentioning: the be[a]ware team is spreading the knowledge of security and privacy to younger students in Switzerland. Great job, check their website!

4. Did you know that Red Hat is offering some of its official courses completely for free for the time being? For example, you could learn about OpenShift or RHEL using the official curriculum. Why not starting today?

5. There are lots of Kubernetes client applications beyond the venerable kubectl. Today we’d like to suggest newcomers to start with Lens, an open-source and free IDE offering a great overview of your deployments, services, everything running in your cluster. A must have in your arsenal for sure.
