Introduction

Application developers building microservices on Kubernetes often encounter two major problems that slow them down:

• Slow feedback loops. Once a code change is made, it must be deployed to Kubernetes to be tested. This requires a container build, push to a container registry, and deployment to Kubernetes. This adds minutes to every code iteration.
• Insufficient memory and CPU locally. Developers attempt to speed up the feedback loop by running Kubernetes locally with minikube or the equivalent. However, resource-hungry applications quickly exceed the compute and memory available locally.

Telepresence is a Cloud-Native Computing Foundation project for fast, efficient development on Kubernetes. With Telepresence, you run your service locally, while you run the rest of your application in the cloud. Telepresence creates a bi-directional network connection between your Kubernetes cluster and your local workstation. This way, the service you’re running locally can communicate with services in the cluster, and vice versa. That allows you to use the compute and memory resources of the cluster, but without having to go through a complete deployment cycle for each change.

In this tutorial, you’ll configure Telepresence on your local machine running MacOS to work with a Kubernetes cluster. You’ll intercept traffic to your cluster and redirect it to your local environment.
