Gateway API With Kuma

01. Install Gateway API

VERSION=0.4.1

# Install the CRDs
kubectl kustomize "github.com/kubernetes-sigs/gateway-api/config/crd?ref=v$VERSION" | kubectl apply -f -

# Install the validating webhook
kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/gateway-api/v$VERSION/deploy/certificate_config.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/gateway-api/v$VERSION/deploy/admission_webhook.yaml

unset VERSION

02. Install Kuma

# At this point you should be in your working copy of the Kuma repository.

# Build Kuma docker images locally.
make images

# This tag will be different depending on the version you checked out. 
TAG=1.4.0-rc1-196-g12afcb6a2

kind load docker-image kumahq/kuma-prometheus-sd:$TAG
kind load docker-image kumahq/kuma-init:$TAG
kind load docker-image kumahq/kumactl:$TAG
kind load docker-image kumahq/kuma-dp:$TAG
kind load docker-image kumahq/kuma-cp:$TAG

unset TAG

kumactl install control-plane --mode=standalone | kubectl apply -f -

03. Add a Kuma GatewayClass

kubectl apply -f <(
cat <<EOF
apiVersion: gateway.networking.k8s.io/v1alpha2
kind: GatewayClass
metadata:
  name: kuma
spec:
  controllerName: gateways.kuma.io/controller
EOF
)

04. Checkout Gateway conformance

# Now switch to the working copy of the gateway-api respository.

# Checkout the in-progress gateway-api PR.
gh pr checkout 969

05. Run conformance

# In the working copy of the gateway-api respository.

# Run the conformance tests. You might have to set KUBECONFIG to point to the right test cluster.

go test -v ./conformance --gateway-class kuma

The sidecar-injection annotation has to be added to the namespaces in conformance/base/manifests.yaml!

Regarding section 01, kubernetes-sigs/gateway-api@ec41fd7 updates certificate_config.yaml and admission_webhook.yaml. The versions in this gist wouldn't work for me, but the updated versions worked fine. There hasn't been a release with these fixes yet but as a workaround this works for me:

kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/gateway-api/master/deploy/certificate_config.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/gateway-api/master/deploy/admission_webhook.yaml

Oh BTW, thank you for this gist!
