Understanding Kubernetes can be difficult or time-consuming. In order to spread knowledges about Cloud technologies I started to create sketchnotes about Kubernetes. I think it could be a good way, more visual, to explain Kubernetes (and others technologies).
We continue the serie of Sketchnotes about Kubernetes, with a focus on what's new in the new version of Kubernetes: v1.27.
Kubernetes 1.27 Complete changelog
If you are interested, I published an entire illustrated book about Kubernetes, available in paperback on Amazon and in digital version on GumRoad: "Understanding Kubernetes in a visual way".
As usual, if you like theses sketchnotes, you can follow me, and tell me what do you think. I will publish others sketchs shortly :-).

ReadWriteOnce -> single NODE access
ReadWriteOncePod -> single POD access
From doc:
How ReadWriteOncePod is different than the ReadWriteOnce access mode?
The ReadWriteOnce access mode restricts volume access to a single node, which means it is possible for multiple pods on the same node to read from and write to the same volume. This could potentially be a major problem for some applications, especially if they require at most one writer for data safety guarantees.
With ReadWriteOncePod these issues go away. Set the access mode on your PVC, and Kubernetes guarantees that only a single pod has access.
Thanks for the documentation.
So, should I edit something in my sketchnote? ;-)
