Kubernetes Ingress with Consul and ngrok

In this presentation, Scott McAllister (ngrok) and I explain how to combine HashiCorp Consul and the ngrok Ingress Controller for Kubernetes to enable developers to get their apps on line with ease.

This version of the talk was given at the HashiCorp booth at KubeCon Europe in April 2023.
