K8s or Die! You must do Kubernetes. Or should you? If so when, where, why? How?! Marco Ceppi @marcoceppi Ryan Beisner @ryanbeisner

Why Kubernetes

Computing in the modern age Virtual Process Machines Containers Traditional Container Coordinator operations KVM Docker / RunC / Rkt Host Linux Filesystem 3

What is Kubernetes

kubernetes is container coordination

storage } compute compute network network for docker-style containers 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
