We will be using a stable distribution of the open-source Jenkins X project, otherwise known as CJXD (CloudBees Jenkins X Distribution). The advantage of using this edition vs. the straight OSS is that it has been tested, and certified for EKS, it also allows for a controlled platform upgrade within your enterprise environment.
At this point, we have a clean cluster named drymartini, which is using Kubernetes 1.14 as shown below.
As of the writing of this workshop, Kubernetes 1.14 is what I am using. However, Jenkins X should support 1.16 once it is available on AWS EKS.
