Lab

Advanced Gateway API Use Cases

Dive deeper into advanced use cases for Cilium's Gateway API.

This lab is a follow-up to the introductory Cilium Gateway API lab.
We highly recommend you do the Cilium Gateway API lab first, if you haven’t done it already.

In this one, you will learn about some additional specific use cases for Gateway API:

• HTTP request & response header rewrite
• HTTP redirect, rewrite and mirror
• Cross-namespace routing
• gRPC routing
• East-West L7 routing with GAMMA
