Kingress controller with Gateway APIs

[nak3]

You mean that the controller to create from Gateway API from KIngress, correct? If so, we will not create it.
Here is the discussion thread (as you might know) - https://knative.slack.com/archives/CA9RHBGJX/p1613698271156800

• phase-1. Create new networking conformance suite by Gateway API resources.
• phase-2. Create makeIngressv2() in serving code. (I think we should allow users to choose KIngress or Ingress v2 by some option during this migration phase.)
• phase-3. Deprecate makeIngress() in serving code.

I read the thread again. sounds like we don't need the ingress v2 controller.

Then about the phases, here is what I read from the chat thread:

• Phase 1: Create makeIngressv2() in knative serving code with a feature flag
• Phase 2: testing serving E2E tests with makeIngressv2() enabled for all impls as extra references
• Phase 3: deprecate makeIngress

I am not very sure what we plan to do about "Create new networking conformance suite by Gateway API resources" mentioned in above comment. Do we plan to add conformance test suites within net-ingressv2 to cover all kingress scenarios, or only basic test suites like https://github.com/knative-sandbox/net-ingressv2/pull/10/files#diff-dd6583ae8832b447f778694426e7a1a3f9da8de2ce0991ebfaad75935c87d6d5 for basic sanity check? Could we just skip this phase considering that we may want to run all E2E tests with makeIngressv2 enabled for all impls?

Thought about this again. I think the value of the work Create new networking conformance suite by Gateway API resources. is to provide various impls the handy conformance check for the ingress v2 to support knative. So if the work could be landed more easily and quickly, I think we can start with this one.

Yes, not only handy conformance check for the ingress v2 providers, but also serving's e2e tests do not cover all networking features so we need the "Create new networking conformance suite by Gateway API resources" which can cover current KIngress tests by ingress v2.

Also, we plan to add all conformance tests. I just added basic test only here #10 because creating all test suites needs "man-power". I think I just add a basic test and common utils in #10, then will ask some volunteers to add other tests.
