„You’re not running vanilla k8s“ - vanilla k8s (marketing term) promising neutrality and protection from vendor lock-in - to run k8s you have to adapt upstream - form communities instead of baking your own k8s distribution!

Kubernetes distributions - added value, e.g. updates - differences: networking, storage, loadbalancing, API server flags,… - https://kubernetes.io/docs/setup/ pick-right-solution/ - risk of vendor lock in

Typhoon - free, minimal and community driven - declarative infrastructure via Terraform - set up, change, destroy - everything wrapped in Terraform modules - uses bootkube under the hood (terraform-render-bootkube) - similarities to CoreOS Tectonic

Slide 11

Slide 11 text

Typhoon - targets GCE, DigitalOcean, AWS and bare metal! - easy to modify in comparison with  other distributions

Slide 12

Slide 12 text

Bootkube - kubernetes incubator project - creates a temporary control plane and bootstraps a self-hosted k8s cluster - uses hyperkube images (multi purpose containter with all k8s components)

Slide 13

Slide 13 text

- makes „infrastructure as code“ possible - unified workflow - abstraction: provider and resources - talk to local and remote APIs in a consistent manner - % terraform init | apply | destroy

Slide 14

Slide 14 text

Building a Typhoon cluster on AWS - single master, two nodes - calico networking - OS: ContainerLinux - nginx ingress deployment - simple example app
