Chapter 7. Knative on OpenShift
OpenShift is Red Hat’s distribution of Kubernetes for building and hosting enterprise-grade cloud native applications. OpenShift enables enterprises to embark upon their hybrid cloud journey by providing a unified developer experience as well as a comprehensive and rich operator experience irrespective of the underlying cloud platform. At its core, OpenShift itself is implemented as a series of Kubernetes Custom Resource Definitions (CRDs) and Operators.
Kubernetes Operators are software extensions that allow you to manage the deployment of Kubernetes applications and services. Operators not only provide automated installation, but can also manage the complete lifecycle of the software including upgrades and monitoring. Operators themselves are managed by the Operator Lifecycle Manager.
OperatorHub.io provides a place to share and discover Operators that have been contributed by the Kubernetes community, such as Apache Kafka, Redis, Jenkins, and many others.
This chapter is aimed at OpenShift developers who want to build and deploy serverless applications on OpenShift. The recipes in this chapter will help these developers get Knative installed and configured on OpenShift using the Operators. You will see that Knative service deployment is going to be similar to what you did with vanilla Kubernetes.
