knative-extensions/net-gateway-api

Integration between Knative and service-apis (ingress v2) for Knative Ingress migration.

Knative net-gateway-api

This component is Beta

net-gateway-api repository contains a KIngress implementation and testing for Knative integration with the Kubernetes Gateway API.

This work is still in early development, which means it's not ready for production, but also that your feedback can have a big impact. You can find the tested Ingress and unavailable features here.

KIngress Conformance Tests

We run our Knative Ingress Conformance tests and are tracking support by different implementations here:

• Contour Epic · Issue #384
• Istio EPIC · Issue #383

Versions to be installed are listed in hack/test-env.sh.

Requirements

1. A Kind cluster
2. Knative serving installed
3. ko (for installing the net-gateway-api)
4. kubectl
5. export KO_DOCKER_REPO=kind.local

Getting started

Install Knative serving

kubectl apply -f https://github.com/knative/serving/releases/latest/download/serving-crds.yaml
kubectl apply -f https://github.com/knative/serving/releases/latest/download/serving-core.yaml

Configure Knative

Ingress

Configuration so Knative serving uses the proper "ingress.class":

kubectl patch configmap/config-network \
  -n knative-serving \
  --type merge \
  -p '{"data":{"ingress.class":"gateway-api.ingress.networking.knative.dev"}}'

(OPTIONAL) Deploy a sample hello world app:

cat <<-EOF | kubectl apply -f -
apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: helloworld-go
spec:
  template:
    spec:
      containers:
      - image: gcr.io/knative-samples/helloworld-go
        env:
        - name: TARGET
          value: Go Sample v1
EOF

Install net-gateway-api

ko apply -f config/

Load tested environment versions

source ./hack/test-env.sh

Install a supported implementation

Istio

# gateway-api CRD must be installed before Istio.
echo ">> Installing Gateway API CRDs"
kubectl apply -f third_party/gateway-api/gateway-api.yaml

echo ">> Bringing up Istio"
curl -sL https://istio.io/downloadIstioctl | sh -
"$HOME"/.istioctl/bin/istioctl install -y --set values.global.proxy.clusterDomain="${CLUSTER_SUFFIX}"

echo ">> Deploy Gateway API resources"
kubectl apply -f ./third_party/istio

Contour

echo ">> Bringing up Contour"
kubectl apply -f "https://raw.githubusercontent.com/projectcontour/contour/${CONTOUR_VERSION}/examples/render/contour-gateway-provisioner.yaml"

# wait for operator deployment to be Available
kubectl wait deploy --for=condition=Available --timeout=60s -n "projectcontour" contour-gateway-provisioner

echo ">> Deploy Gateway API resources"
kubectl apply -f ./third_party/contour

(OPTIONAL) For testing purpose (Istio)

Use Kind with MetalLB - https://kind.sigs.k8s.io/docs/user/loadbalancer

For Mac setup a SOCK5 Proxy in the Docker KinD network and use the ALL_PROXY environment variable

docker run --name kind-proxy -d --network kind -p 1080:1080 serjs/go-socks5-proxy
export ALL_PROXY=socks5://localhost:1080
curl 172.18.255.200 -v -H 'Host: helloworld-test-image.default.example.com'
