Overview of this book

For IT professionals working with Red Hat OpenShift Container Platform, the key to maximizing efficiency is understanding the powerful and resilient options to maintain the software development platform with minimal effort. OpenShift Multi-Cluster Management Handbook is a deep dive into the technology, containing knowledge essential for anyone who wants to work with OpenShift. This book starts by covering the architectural concepts and definitions necessary for deploying OpenShift clusters. It then takes you through designing Red Hat OpenShift for hybrid and multi-cloud infrastructure, showing you different approaches for multiple environments (from on-premises to cloud providers). As you advance, you’ll learn container security strategies to protect pipelines, data, and infrastructure on each layer. You’ll also discover tips for critical decision making once you understand the importance of designing a comprehensive project considering all aspects of an architecture that will allow the solution to scale as your application requires. By the end of this OpenShift book, you’ll know how to design a comprehensive Red Hat OpenShift cluster architecture, deploy it, and effectively manage your enterprise-grade clusters and other critical components using tools in OpenShift Plus.

Types of routes

Routes are the representation of a configuration on an ingress internal load balancer for a specific application to expose a Kubernetes service to a DNS name, such as example.apps.env.hybridmycloud.com. When a route is created, OpenShift automatically configures a frontend and backend in the Ingress’ HAProxy pod to publish the URL and make the traffic available from the outside world.

Routes can be published using either the HTTP or HTTPS protocol. For HTTPS, three different types of routes define how the TLS termination works in the SSL stream between the user and the pod. In the following subsections, we will walk you through each of them.

Passthrough routes

A passthrough route, as the name suggests, is a configuration in which the packages are forwarded straight to the network service without doing a TLS termination, acting as a Layer 4 load balancer. Passthrough is often used with applications that provide their own TLS termination inside the application...
