TL;DR: We're now LearnKube! Newsletter moves to Kube Today

After 8 years of teaching Kubernetes as Learnk8s, we've moved to our new home: LearnKube.com.

Nothing changes about what we do - same instructors, same hands-on labs, same deep-dive Kubernetes training that over 3,000 engineers have trusted to level up their skills.

So why the change?

Sometimes, the universe nudges you in the right direction.

LearnKube actually fits better with our family of brands (Kube Events, Kube Careers, KubeFM and the news we publish on Kube Architect, Kubesploit and Kube Builders)

One more thing!

I'm launching a new project soon called Kube Today (you are the first to know, this is still a WIP). Kube Today has a mission similar to the newsletter: to surface news, tutorials, articles, events, jobs, etc., on a daily basis. I will move this newsletter to Kube Today as it aligns better with the goal.

Here is what you need to know:

• The newsletter won't stop, and the format won't change.

• You will receive the newsletter from a new sender ( weekly@kube.today)

• The newsletter might end up in spam if you don't whitelist the address.

Exciting times!
