Advanced Gateway API Use Cases
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:
- Traffic splitting
- HTTP request header rewrite
- HTTP response header rewrite
- TLS Passthrough
- Cross-namespace routing
Main steps in the lab
