Kubernetes Gateway API is a Fascinating Topic ??

It is one of the best ways to manage - "evolving network infrastructure" within Kubernetes clusters. It also addresses the limitations of Ingress API with a more robust and standardized approach.

NOTE: If you resonate with my work, please consider joining me on Youtube and Substack. I totally appreciate your support. Thank You.

The Gateway API is an official Kubernetes project. The difference between Ingress and Gateway API is massive. Because the Gateway API supports:

1. Role-based access control.
2. API supports for future advancements.
3. Integration with service meshes.
4. Multi protocol support (HTTP, TCP, gRPC.)

Let's me just expand a little bit about Multi protocol support.

Package v1alpha2 of Gateway API contains API support for GRPCRoute, HTTPRoute, TCPRoute, TLSRoute and UDPRoute. These Routes define how incoming traffic (requests) should be handled.

In simpler terms, this package provides the building blocks for defining how different types of network traffic (gRPC, HTTP, TCP, etc.) should be routed within a Kubernetes cluster using the Gateway API.

Here's more you should know.

When using Gateway API to manage incoming traffic. This traffic is managed by gateway resources which are defined below in short.

GatewayClass: Defines which controller manages the traffic (example: haproxy controller)

Gateway: Listens to a port with protocol. Works with a GatewayClass mentioned above.

Route: Maps requests (based on criteria - path) to a backend service in cluster.

Kubernetes Gateway API has awesome capabilities. I've just covered absolute basics of the subject.

That's it from my side. Today, if we work hard with a humble heart, tomorrow holds hope for a brighter future ??
