thanks @zirain, this PR is a massive addition for the project to improve e2e and reduce regressions for our Extension APIs

[arkodg]

thanks for addressing comments @zirain , this PR adds a fork for the gateway-api repo which im hoping we dont need, and the upstream PR you raised is merged and can be brought in to this project soon

yes, we should not include my fork repo. let's wait upstream PR merged.

another option is to write our own utils/suite package and we can write a custom Setup with a custom kubectl apply but we leverage the existing Run

unless kubernetes-sigs/gateway-api#1899 is unacceptable.

cc @arkodg , this's ready to go, PTAL.

How about run-e2e-ratelimit ? Since we might need to add other e2e tests like auth, etc.

[zirain]

this's the entrypoint for all e2e tests, for now there's only ratelimit tests

[arkodg]

only nit here would be to split up redis install with patching/updating the EnvoyGateway Configmap, but it can be improved later

LGTM thanks for adding the e2e infra, should give us more confidence while building out extended features
