+## OpenShift IPI Baremetal Lab (oibl)
+
+### Architecture
+![OpenShift IPI Baremetal Lab](https://raw.githubusercontent.com/kevydotvinu/ocp-ipi-baremetal-lab/main/.img/ocp-ipi-baremetal-lab.png)
+
+### Prerequisites
+* A virtual machine with the below resources:
+
+| CPU | RAM | Storage |
+|-----|-----|---------|
+| 30 | 120 GB | 300 GB |
+
+* Nested virtualization
+
+![RHEV CPU Pass-through](https://raw.githubusercontent.com/kevydotvinu/disconnectedOCPonKVM/main/.img/passThroughHostCpu.png)
+
+* Custom Fedora CoreOS
+  - Either download an ISO image from [here]().
+  - Or [build](#build-custom-fedora-coreos) one using the [CoreOs Assembler](https://github.com/coreos/coreos-assembler) with an [ignition](#generate-ignition) file and a [fedora-coreos-config](https://github.com/kevydotvinu/fedora-coreos-config).
+
+### Preparation
+```bash
+$ coreos-installer install /dev/sda
+$ sudo systemctl reboot
+$ ssh kni@<IP> (Enter `Kni@123` as password)
+$ sudo systemctl reboot
+```
+
+### Usage
+```bash
+oibl help
+oibl ssh-pullsecret OCM_TOKEN=<OCM_TOKEN>
+oibl install-config RELEASE=stable-4.10
+oibl cluster LOGLEVEL=info
+```
+### Build custom Fedora CoreOS
+##### Define a bash alias to run cosa
+* See [this](https://github.com/coreos/coreos-assembler/blob/main/docs/building-fcos.md#define-a-bash-alias-to-run-cosa).
+##### Initialize
+```bash
+$ mkdir oibl
+$ cd oibl
+$ cosa init https://github.com/kevydotvinu/fedora-coreos-config
+```
+##### Build
+```bash
+$ make -C src/config generate-iso
+```
+##### Check the ISO file
+```bash
+$ find -iname "*.iso" | tail -n 1
+```
+### Generate ignition
+```bash
+git clone https://gist.github.com/kevydotvinu/d8442779a1fd6de82fbc81c77047bd41
+cd d8442779a1fd6de82fbc81c77047bd41
+make
+```
