Understanding RHDH Build Types and Components

Introduction

To deploy Red Hat Developer Hub (RHDH) on OpenShift, multiple container images work together through the OpenShift Operator Lifecycle Manager (OLM). This document explains the different types of builds available and how they are distributed through various container registries.

Three main components are involved in a RHDH deployment:

• The RHDH application itself (the developer portal)
• The RHDH operator (manages the lifecycle of RHDH instances)
• The Index Image Builder (IIB - a catalog of available operator versions)
