Examples of using a WAF in front of ROSA / OSD on AWS / OCP on AWS

Problem Statement

  1. Operator requires WAF (Web Application Firewall) in front of their workloads running on OpenShift (ROSA)

  2. Operator does not want WAF running on OpenShift to ensure that OCP resources do not experience Denial of Service through handling the WAF

Quick Introduction by Paul Czarkowski & Ryan Niksch on YouTube

Solutions

Cloud Front -> WAF -> CustomDomain -> $APP

This is the preferred method and can also work with most third party WAF systems that act as a reverse proxy

Uses a custom domain, custom route, LE cert. CloudFront and WAF

Application Load Balancer -> ALB Operator -> $APP

Installs the ALB Operator, and uses the ALB to route via WAF, one ALB per app though!
