Experimenting with Gateway API using kind

Experimenting with Gateway API using kind Overview Prerequisites Create a kind cluster Install cloud-provider-kind Experimenting with Gateway API Deploy a Gateway Deploy a demo application Create an HTTPRoute Test your route Troubleshooting Check the Gateway status Check the HTTPRoute status Check controller logs Cleanup Remove Kubernetes resources Stop cloud-provider-kind Delete the kind cluster Next steps A final word of caution This document will guide you through setting up a local experimental environment with Gateway API on kind. This setup is designed for learning and testing. It helps you understand Gateway API concepts without production complexity. In this guide, you will: Set up a local Kubernetes cluster using kind (Kubernetes in Docker) Deploy cloud-provider-kind , which provides both LoadBalancer Services and a Gateway API controller Create a Gateway and HTTPRoute to route traffic to a demo application Test your Gateway API configuration locally This setup is ideal for learning, development, and experimentation with Gateway API concepts. Before you begin, ensure you have the following installed on your local machine: Docker - Required to run kind and cloud-provider-kind kubectl - The Kubernetes command-line tool kind - Kubernetes in Docker curl - Required to test the routes Create a new kind cluster by running: kind create cluster kind create cluster This will create a single-node Kubernetes cluster running in a Docker container. Next, you need cloud-provider-kind , which provides two key components for this setup: A LoadBalancer controller that assigns addresses to LoadBalancer-type Services A Gateway API controller that implements the Gateway API specification It also automatically installs the Gateway API Custom Resource Definitions (CRDs) in your cluster. Run cloud-provider-kind as a Docker container on the same host where you created the kind cluster: VERSION = " $( basename $( curl -s -L -o /dev/null -w '%{url_effective}' https://github. com/kubernetes-sigs/cloud-provider-kind/releases/latest )) " docker run -d --name cloud-provider-kind --rm --network host -v /var/run/docker. sock:/var/run/docker. sock registry. k8s. io/cloud-provider-kind/cloud-controller-manager: ${ VERSION } VERSION = " $( basename $( curl -s -L -o /dev/null -w '%{url_effective}' https://github.
