We'll explore some of the skills and knowledge required for operating Kubernetes clusters. We'll deal with subjects that are often not studied at the very beginning but only after we get bored with Kubernetes' core features like Pod, ReplicaSets, Deployments, Ingress, PersistentVolumes, and so on. We'll master subjects we often dive into after we learn the basics and after we automate all the processes. We'll explore monitoring, alerting, logging, auto-scaling, and other subjects aimed at making our cluster resilient, self-sufficient, and self-adaptive.
