Chapter 10. HTTP configuration

HTTPS redirection provides redirection for incoming HTTP requests. These redirected HTTP requests are encrypted. You can enable HTTPS redirection for all services on the cluster by configuring the httpProtocol spec for the KnativeServing custom resource (CR).

apiVersion: operator.knative.dev/v1beta1
kind: KnativeServing
metadata:
  name: knative-serving
spec:
  config:
    network:
      httpProtocol: "redirected"
...

apiVersion: operator.knative.dev/v1beta1
kind: KnativeServing
metadata:
  name: knative-serving
spec:
  config:
    network:
      httpProtocol: "redirected"
...

You can enable or disable HTTPS redirection for a service by configuring the networking.knative.dev/http-option annotation.

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: example
  namespace: default
  annotations:
    networking.knative.dev/http-protocol: "redirected"
spec:
  ...

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: example
  namespace: default
  annotations:
    networking.knative.dev/http-protocol: "redirected"
spec:
  ...

You can enable the HTTP/1 full duplex support for a service by configuring the features.knative.dev/http-full-duplex annotation.

The following example shows how you can use this annotation in a Knative Service YAML object at the revision spec level:

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: example-service
  namespace: default
spec:
  template:
    metadata:
      annotations:
        features.knative.dev/http-full-duplex: "Enabled"
...

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: example-service
  namespace: default
spec:
  template:
    metadata:
      annotations:
        features.knative.dev/http-full-duplex: "Enabled"
...
