+
+## Introduction
+
+This article is WIP to describe all steps required for our first
+production kubernetes cluster and the services that we run in it.
+
+## Setup
+
+### Bootstrapping
+
+* All nodes are running [Alpine Linux](https://alpinelinux.org)
+* All nodes are configured using [cdist](https://cdi.st)
+  * Mainly installing kubeadm, kubectl, crio *and* docker
+  * At the moment we try to use crio
+* The cluster is initalised using **kubeadm init --config
+  k8s/c2/kubeadm.yaml** from the [ungleich-k8s repo](https://code.ungleich.ch/ungleich-public/ungleich-k8s)
+
+### CNI/Networking
+
+* Calico is installed using **kubectl apply -f
+  cni-calico/calico.yaml** from the [ungleich-k8s
+  repo](https://code.ungleich.ch/ungleich-public/ungleich-k8s)
+* Installing calicoctl using **kubectl apply -f
+  https://docs.projectcalico.org/manifests/calicoctl.yaml**
+* Aliasing calicoctl: **alias calicoctl="kubectl exec -i -n kube-system calicoctl -- /calicoctl"**
+* All nodes BGP peer with our infrastructure using **calicoctl create -f - < cni-calico/bgp-c2.yaml**
+
+### Persistent Volume Claim support
+
+* Provided by rook
+* Using customized manifests to support IPv6 from ungleich-k8s
+
+```
+for yaml in crds common operator cluster storageclass-cephfs storageclass-rbd toolbox; do
+    kubectl apply -f ${yaml}.yaml
+done
+```
+
+### Flux
+
+Starting with the 2nd cluster?
