Certified Kubernetes Application Developer (CKAD)

Virtualization, Kubernetes

Course delivers basics of Kubernetes, an open-source platform for container orchestration. We’ll talk about Kubernetes architecture and look at how to move around. We’ll use practical examples to demonstrate the building blocks of an application running in Kubernetes and how to modify them.

Course covers identical topics as course KUBER1 and adds topics that appear in the Certified Kubernetes Application Developer certification by Linux Foundation. The certification itself is not covered by the course fee, nor is the certification part of the course.

"Školení bylo rozděleno do dvou částí - základy Kubernetes s Věrošem, který parádně projel základy, vnitřní fungování a principy, společně s dobře vypracovanými cvičeními. Třetí den byl pokročilejší s Ondřejem A. Benešem, který se dostal se více do hloubky a díky tomu, že jsme byli jen dva účastníci, bylo školení opravdu na míru. Probrali jsme témata nutná pro CKAD zkoušku a s náplní jsem plně spokojen. Přístup Ondřeje mi byl více po chuti. Děkuji a přeji krásné svátky."

"Very knowledgeable teacher. Although I knew the basics upfront, he provided enough in-depth knowledge behind the abstractions to make the class interesting. Covered a lot of ground in just a few days. It would have been better if minikube would have come pre-installed on the VMs. We didn't learn much by installing it and it took quite some time debugging. Also please next time send a calendar invite :). All in all great course, thanks"
