Or should you? If so when, where, why? How?!

Kubernetes

Why

Computing in the modern age

Container Coordinator

KVM Docker / RunC / Rkt

Kubernetes

What is

kubernetes is container coordination

compute network for docker-style containers storage } compute network storage

rollout / rollback scale up / scale back service discovery load balancing self healing

EasyRSA

Provides PKI / CA for TLS certs to all components

ETCD

Distributed data store / backend for Kubernetes

K8S Master

API server, scheduler, controller manager

K8S Worker

Kubelet, SDN, Kube Proxy, Docker

Converged Kubernetes
