"Introduction to Kubernetes"
summary
Overview claims Kubernetes converges cluster state and shows concrete tools and results: uses miniCube, Helm and Cube control to push a container image and inspect the API, runs a sample app that serves a random subreddit from a list of 280 subreddits, deploys a ReplicaSet-backed Deployment with a LoadBalancer service, demonstrates traffic hitting multiple Pods and scales from 3 pods to 6 replicas successfully.
