-# Introduction to kubectl 
-
-## Prerequisites
-
-For using this you must install the following tools: 
-
-- Python 
-- Pip
-- Kubectl 
-- Openstack-Client
-
-### Python 
-
-Install python and pip for your OS, if it is not installed. This is already done at the NetLab PCs.
-
-### Installing kubectl and arkade
-
-Run this in a **bash** terminal to download arkade and install kubectl:
-
-For windows you can use e.g. the **Git Bash** terminal.
-
-```bash
-curl -sLS https://dl.get-arkade.dev | sh
-arkade get kubectl
-# To load the path to the binary
-export PATH=$PATH:$HOME/.arkade/bin/
-```
-
-With arkade you can also install other tools: ```arkade get``` to see all possibilities.
-
-### Openstack Client
-
-To install the Openstack client and the magnum package:
-
-If you are using Windows, you must start the bash terminal with **Administrator** privileges!
-
-```bash
-pip3 install openstackclient python-magnumclient
-# Download the Openstack RC File from your Openstack account
-# Load the file
-source {USERNAME}-openrc.sh
-```
-
-### Download the kubeconfig 
-
-Download the kubeconfig file for your cluster from OpenStack.
-
-```bash
-# Before using this, check if Openstack RC File is loaded!
-openstack coe cluster config {CLUSTER_NAME}
-# Then run the given command in terminal
-export ...
-# Now you are able to run kubectl commands at your Kubernetes cluster
-```
-
-## Deployment of the needed description in kubernetes
-
-These are two approaches to create the description in Kubernetes: 
-
-```bash
-# create a namespace 
-kubectl create namespace web-test
-
-# Then choose one of the following ways:
-# (1) Create the description
-kubectl create -f nginx.yml -f service.yml
-
-# (2) Create or update descriptions if existing
-kubectl apply -f nginx.yml -f service.yml
-```
-
-## To show it is working
-
-Here are some useful commands:
-
-```bash
-# show nodes
-kubectl get nodes
-
-# show pods for our namespace
-kubectl get -n web-test pods 
-
-# show deployments for our namespace
-kubectl get -n web-test deployment
-
-# show services for our namespace
-kubectl get -n web-test service
-
-# show logs of deployed nginx instances
-kubectl logs -n web-test deployment/nginx-deployment
-```
-
-## Scaling up and down
-
-```bash
-# scale up instances to 5
-kubectl scale -n web-test deployment/nginx-deployment --replicas=5
-
-# scale down instances again to 3
-kubectl scale -n web-test deployment/nginx-deployment --replicas=3
-
-```
-
-
-## To see it is working in the browser ;)
-
-The nginx instances are reachable at the floating ips of the **node**-instances at port **30007** in our case.
-
-
-## Many other things can be done ;)
-
-- Autoscaling 
-- Detailled Service functions (LoadBalancer, ...)
-- Dashboard
-- FaaS Setup ;) 
-- ...
