OpenShift Baremetal Deploy

This repository is intended to store resources and deployment artifacts for bare metal OpenShift KNI clusters (currently OpenShift 4.3)

It also contains optional features focused on low-latency workloads, NFV workloads, etc.

Installation artifacts

• Installation Steps
• Using Baremetal-prep.sh

Optional features

• Performance. Performance related features like Hugepages, Real time kernel, Cpu Manager and Topology Manager.
• Bonding. A helper script to create bonding devices with ignition and/or nmstate.
• DPDK. Example workload that uses DPDK libraries for packet processing.
• Kubernetes NMstate. Node-networking configuration driven by Kubernetes and executed by nmstate.
• PTP. This operator manages cluster wide Precision Time Protocol (PTP) configuration.
• SCTP. These assets enables Stream Control Transmission Protocol (SCTP) in the RHCOS worker nodes.
• SRIOV. The SR-IOV Network Operator creates and manages the components of the SR-IOV stack.

Performance tuning

The Performance Tuning folder contains some assets intended to improve performance such as:

• Huge Pages
• Topology Manager
• CPU manager
• Real time kernel (including a new worker-rt Kubernetes/OpenShift node role)

Those assets are applied mainly via the Node Tuning operator and/or the Machine Config operators.
