Experimenting with Gateway API using kind
This document provides a guide for setting up a local experimental environment for learning Gateway API concepts using kind. It emphasizes that this setup is not for production use. The process involves creating a kind Kubernetes cluster and deploying cloud-provider-kind, which offers LoadBalancer Services and a Gateway API controller. Users will then create a Gateway, deploy a demo echo application, and configure an HTTPRoute to direct traffic to this application. The guide includes steps to test the Gateway API configuration and provides troubleshooting tips for common issues. Finally, it outlines the cleanup process to remove all created resources and suggests next steps for exploring production-ready implementations and advanced Gateway API features. This local setup is specifically designed for understanding Gateway API principles without production complexities. It requires Docker, kubectl, kind, and curl to be installed. The cloud-provider-kind component simulates a cloud-enabled environment by providing necessary controllers and CRDs. Creating a Gateway involves defining a GatewayClass and listener configurations that accept specific hostnames and protocols. Deploying the echo application involves creating a namespace, Service, and Deployment. Configuring the HTTPRoute links the Gateway to the echo application for a specific hostname. Testing involves using curl to send a request to the Gateway's IP address with the defined hostname. Checking resource statuses and controller logs are recommended for troubleshooting. Cleanup involves deleting namespaces, stopping the cloud-provider-kind container, and deleting the kind cluster.
