Transcript

1. Ingress future directions sig-network
2. Ingress spec Overview Virtual Host Path k8s Service k8s Service Path Path Virtual Host TLS, protocol
3. Issues • Warts: specification is not precise (also no conformance tests). • Portability (most “interesting” configuration is in annotations). • Annotations create a parallel structure, unwieldy. • Features...
4. Choices • Move toward GA with changes to allow extensions? • Break up into portable vs non-portable objects? • Move out of core? (API predates robust extension mechanisms). • Allow for divergence (may the best Spec win)? ◦ Some evidence for convergence: Envoy xDS API
5. Questions for the community • Any experiences porting your Ingress spec between implementations? • Is it sufficiently expressive? • What to should be “standard”? ◦ Termination (protocols, TLS) ◦ Description of the application routing (request → services)
6. Open discussion
