-# Zammad kubernetes example deployment
-
-This is a proof of concept of a Kubernetes deployment, which should be considered
-beta and not ready for production.
-
-## Prerequisites
-
-- Kubernetes 1.8.x Cluster with at least 1 worker node, 2 CPUs and 6 GB of RAM
-- Change the ingress to your needs
-
-
-## Deploy Zammad
-
-### Install on Minikube
-
-* Install kubectl
-  * https://kubernetes.io/docs/tasks/tools/install-kubectl/
-* Install Minkube
-  * https://github.com/kubernetes/minikube
-* minikube start --memory=6144 --cpus=2
-* minikube addons enable ingress
-* echo "$(minikube ip) zammad.example.com" | sudo tee -a /etc/hosts
-* kubectl apply -f .
-* minikube dashboard
-  * switch to namespace "zammad"
-  * open "Overview" and wait until all pods are green
-* access zammad on:
-  * http://zammad.example.com
-
-
-### Install on Google Kubernetes Engine
-* connect to cluster via gcloud command
-* kubectl proxy
-* kubectl apply -f .
-* open dashboard in browser
-  * http://127.0.0.1:8001/ui
-* if everything is green add backends / ingress rules to create external endpoint
-
-
-## If you want to help to improve the Kuberntes deployments here are some todos:
-* add cpu & mem limits
-* add rolling upgrade strategy to deployments
-* add RBAC
