Configure Contour adapter

This page describes how to install and configure the Contour adapter for Knative: net-contour.

Before you begin

This installation requires a Kubernetes cluster with Contour installed.

For information about Contour versions, see the Contour Compatibility Matrix.

Install and configure the adapter

1. Install the Knative Contour controller:

   kubectl apply -f https://storage.googleapis.com/knative-nightly/net-contour/latest/net-contour.yaml
   

2. Configure Knative Serving to use Contour by default:

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

3. Get the External IP address or full qualified domain name (CNAME):

   kubectl --namespace contour-external get service envoy
   

   Use this value to configure your external DNS records.

The adapter's configurations are performed natively through Contour. For more information and resources see Contour home page.
