 Install RedHat OKD 3.11 on your own server.  For a local only install, it is suggested that you use CDK or MiniShift instead of this repo.  This install method is targeted for a single node cluster that has a long life.
 
 This repository is a set of scripts that will allow you easily install the latest version (3.11) of OKD in a single node fashion.  What that means is that all of the services required for OKD to function (master, node, etcd, etc.) will all be installed on a single host.  The script supports a custom hostname which you can provide using the interactive mode.

+# Install on Hetzner-bare-metal Server
+
+In oder to have a more openshift-a-like environment there is now a manual of how to run this on a bare-metal-box.
+Please check: [all-in-one-hetzner-bare-metal](all-in-one-hetzner-bare-metal.md)
+
 ## Installation
 
 1. Create a VM as explained in https://www.youtube.com/watch?v=ZkFIozGY0IA (this video) by Grant Shipley

+# ODK bare metal deployment
+
+This  manual describes a way of how to run the installation on a bare metal hetzner box.
+
+It is meant to complement [Hetzner OCP](https://github.com/RedHat-EMEA-SSA-Team/hetzner-ocp), where a cluster like setup is not needed or appropriate.
+
+This is done without installing the logging/metrics System, because there is no value added when someone needs an environment for app-developement/customising apps or executing a showcase.
+The purpose is to have a real openshift smell like development-sandbox but not a fully blown cluster.
+
+The procedure can be executed in approximately 3-4h, where attention is needed for 1-2h approx.
+
+
+#Install Base OS
+
+There is a preparation to be achieved.
+
+This is taken from:
+
+https://github.com/RedHat-EMEA-SSA-Team/hetzner-ocp#install-instructions
+
+The simplest way of partitioning is:
+```
+DRIVE1 /dev/sda
+DRIVE2 /dev/sdb
+SWRAID 1
+SWRAIDLEVEL 1
+BOOTLOADER grub
+HOSTNAME CentOS-76-64-minimal
+PART /boot ext3     512M
+PART lvm   vg0       all
+
+LV vg0   root   /       ext4     200G
+LV vg0   swap   swap    swap       5G
+LV vg0   tmp    /tmp    ext4      10G
+LV vg0   home   /home   ext4      40G
+
+
+IMAGE /root/.oldroot/nfs/install/../images/CentOS-76-64-minimal.tar.gz
+```
+
+To specify the rest of available space on the drive, you can easily use "all" at the last partition.
+
+There is more information about the [**Installimage script**](https://wiki.hetzner.de/index.php/Installimage/en).
+
+For a box 2*2GB, if the image is not available just check for the next version of CentOS.
+
+After the image has installed, first update packages and enable SELinux, as it comes disabled:
+
+```
+$ yum -y update
+$ vi /etc/selinux/config
+
+SELINUX=enforcing
+
+# Restart the server.
+$ sync; reboot
+
+# Check SELinux status.
+$ getenforce
+-> Enforcing
+```
+
+Install the following packages:
+
+```
+$ yum -y install screen git
+```
+
+# Install ODK
+
+
+Please read the section upfront but slightly change some commands
+
+https://github.com/gshipley/installcentos
+
+Skip step 2.
+
+and clone with:
+
+```
+# I recommend use screen program to prevent session termination once install script executed.
+$ screen
+# Use your Git-Fork or use:
+$ export GIT_USER=gshipley
+$ git clone https://github.com/${GIT_USER}/installcentos
+```
+Then Export the following variables; these will take control over the
+process os installation where relevant:
+
+```
+### Optional: export SCRIPT_REPO=browse to your **RAW** fork of rep:
+### export SCRIPT_REPO=https://raw.githubusercontent.com/${GIT_USER}/installcentos/master
+
+$ export METRICS="False"
+$ export LOGGING="False"
+
+```
+
+3. Execute the installation script
+
+```
+$ cd installcentos
+$ ./install-openshift.sh
+```
+
+# Secure System with Firewall
+
+While the installation is running you might want to configure the FireWall:
+
+https://github.com/RedHat-EMEA-SSA-Team/hetzner-ocp#firewall
