There's some discussion at https://kubernetes.slack.com/archives/C05J0D0V525/p1698851598969379 about an issue I faced due to rules being too costly for httproutes when it comes to parentRef.

kuadrant-operator have logged it here GEP: Add Name to HTTPRouteRule and HTTPRouteMatch · Issue #995 · kubernetes-sigs/gateway-api

And have a solution on their side Kuadrant/kuadrant-operator@56a9a34

It's blocking us from running our integration tests because the environment fails on CRD creation producing the following error

unable to install CRDs onto control plane: unable to create CRD instances: unable to create CRD \"httproutes.gateway.networking.k8s.io\": CustomResourceDefinition.apiextensions.k8s.io \"httproutes.gateway.networking.k8s.io\" is invalid: [spec.versions[0].schema.openAPIV3Schema.properties[spec].properties[parentRefs].x-kubernetes-validations[0].rule: Forbidden: estimated rule cost exceeds budget by factor of more than 100x (try simplifying the rule, or adding maxItems, maxProperties, and maxLength where arrays, maps, and strings are declared), spec.versions[0].schema.openAPIV3Schema.properties[spec].properties[parentRefs].x-kubernetes-validations[0].rule: Forbidden: contributed to estimated rule cost total exceeding cost limit for entire OpenAPIv3 schema, spec.versions[0].schema.openAPIV3Schema: Forbidden: x-kubernetes-validations estimated rule cost total for entire OpenAPIv3 schema exceeds budget by factor of more than 100x (try simplifying the rule, or adding maxItems, maxProperties, and maxLength where arrays, maps, and strings are declared)]

For running through the walkthrough one issue is faced for the istio class gateway, which is that the Programmed status remains unknown.

This could be addressed by istio/istio@73e4596 which is being cherrypicked to release 1.20.0 of istio. We are currently running 1.17.0.

1.20.0-beta.0 is available https://hub.docker.com/r/istio/pilot/tags but we may have a short wait for 1.20.0 to be available.

Update the following https://github.com/search?q=repo%3AKuadrant%2Fmulticluster-gateway-controller%201.17.0&type=code to move to the new version once it's available.
