As part of my goal to obtain the Certified Kubernetes Administrator (CKA) certification, I went through the Kubernetes documentation to find the specific links that map to the domain knowledge objectives for the v1.19 exam.
I’ve been slowly working towards CKA and there is a significant change to the curriculum with the recent announcement from the Cloud Native Computing Foundation (CNCF) that the Certified Kubernetes Administrator (CKA) exam curriculum will be updated in September 2020 to cover Kubernetes v1.19. The v1.19 curriculum is a huge change from the v1.18 curriculum I’ve been studying and I prepared this comparison to help with my studies and hope it provides some clarity to those in a similar situation as me.
Kubernetes v1.19 hasn’t been finalized yet but there will certainly be new features, added commands, and others deprecated as part of the update. But that’s not the only change — the exam curriculum is also changing a lot!
I must admit that I wasn’t on the Kubernetes bandwagon from beginning. However, I’ve seen it mature rapidly over the last 4 years with an expanding ecosystem and high rate of adoption that has given me confidence that there is a future with Kubernetes and now is the time to invest in learning it. Here are the 3 things I observed over the last 12-18 months to solidify that now is the time for me to focus on becoming a Kubernetes expert:
Cloud Native Landscape Explosion
The Cloud Native Computing Foundation (CNCF) began publishing the CNCF Cloud Native Landscape back in 2016 to illustrate the projects and enterprise software that are part of the cloud native ecosystem and community. The Cloud NativeLandscape graphic originally contained three projects: Kubernetes, Prometheus, and Opentracing. Today, it includes over 48 (not including CNCF member/non-member products and projects)! Observing this type of growth signals heavy investment by organizations and individuals to improving core functionality of Kubernetes or filling gaps in the ecosystem.
