Kourier

[This component is GA](https://github.com/knative/community/tree/main/mechanics/MATURITY-LEVELS.md)

Kourier is an Ingress for Knative Serving. Kourier is a lightweight alternative for the Istio ingress as its deployment consists only of an Envoy proxy and a control plane for it.

Kourier is passing the knative serving e2e and conformance tests: Kourier Testgrid.

Getting started

• Install Knative Serving, ideally without Istio:

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

• Then install Kourier:

kubectl apply -f https://github.com/knative/net-kourier/releases/latest/download/kourier.yaml

• Configure Knative Serving to use the proper "ingress.class":

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

• (OPTIONAL) Set your desired domain (replace 127.0.0.1.nip.io to your preferred

domain):

kubectl patch configmap/config-domain \
-n knative-serving \
--type merge \
-p '{"data":{"127.0.0.1.nip.io":""}}'

• (OPTIONAL) Deploy a sample hello world app:

cat kourier.knative.dev/disable-http2=true --namespace

A good use case for this configuration is DomainMapping with Websocket
