"If Ingress is the Legacy Path, then the Gateway API is the modern highway. In this guide, I will walk you through a complete migration demonstrating how to swap out your old Ingress controllers for Envoy Gateway. We won't just move traffic; we'll leverage Envoy's power to implement seamless request mirroring and more robust, path-based routing that was previously hidden behind complex annotations."
"This command installs Envoy Gateway into your cluster using Helm, pulling the chart directly from Docker Hub's OCI registry. It creates a dedicated envoy-gateway-system namespace and deploys the Envoy Gateway controller there, which will watch for GatewayClass and Gateway resources across your cluster."
The Gateway API represents the modern evolution beyond Kubernetes' legacy Ingress standard, offering more expressive and role-oriented traffic management capabilities. Envoy Gateway provides a powerful implementation of this standard, enabling advanced features such as request mirroring and sophisticated path-based routing that previously required complex annotations. The migration process begins with installing the Envoy Gateway controller via Helm into a dedicated namespace, which watches for GatewayClass and Gateway resources. Subsequently, administrators deploy GatewayClass and Gateway resources to establish the routing infrastructure. This approach leverages Envoy's capabilities to provide more robust and flexible ingress management compared to traditional Ingress controllers, requiring MetalLB configuration as a prerequisite for local Minikube clusters.
