What is Qubinode Installer?
Qubinode-installer is an utility tool that facilates the quick deployment of an array of Red Hat products like Red Hat Openshift Container Platform, Red Hat Identity Manager, Red Hat Satellite, etc.. on a single piece of hardware by leveraging the KVM hypervisor.
The benefits of using qubinode
The Qubinode Project provides a very cost effective way to quickly stand up a lab environment on a single piece of hardware. Your most expensive investment would be the procurement of the hardware itself. This is a cheaper approach than having to pay a license fee to use a type 1 hypervisor like VMWare/VSphere or having to pay a fee to use AWS EC2 instances.
Motivation
The primary focus of this project is make it easy for you to deploy an OpenShift cluster on a single bare metal node with production like characteristics. Please visit The Qubinode Project landing page for step by step easy to follow guide on how to get started.
What is OpenShift?
Red Hat OpenShift Container Platform (OCP) - is Red Hat's private platform as a service product, built around a core of application containers powered by Kubernetes and on the foundations of Red Hat Enterprise Linux.
Resource requirements for OpenShift cluster
Baremetal Hardware
- At least 32 GiB of memory, 128 GiB is recommended.
- At least 300 GiB SSD or NVME dedicated storage, 1TB is recomneded.
The qubinode-installer can deploy a 3 node cluster on a system with 32GiB memory. For the best possible experince 128 GiB of memory is recommended. This will allow for the default deployment of a cluster with 3 controlplane and 3 computes.
Software
- Red Hat Enteprise Linux 9.0 Refer to the hardware recommendation for lab hadware suggestions. One of the supported base OS is Red Hat Enterprise Linux 9.0 refer to the Getting Started Guide
- Centos 8 Streams is supported base OS.
- Or Fedora 36 (Testing) is a supported base OS.
