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
• Installing IPI on BM using the Ansible Playbook
  • Versions: 4.3, 4.4

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.
• SR-IOV. The SR-IOV Network Operator creates and manages the components of the SR-IOV stack.
• CNV. Container-native virtualization is an add-on to OpenShift Container Platform that allows you to run and manage virtual machine workloads alongside container workloads.

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.
