Chapter 10. HTTP configuration
10.1. Global HTTPS redirection
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).
10.1.1. HTTPS redirection global settings
Example KnativeServing CR that enables HTTPS redirection
apiVersion: operator.knative.dev/v1beta1
kind: KnativeServing
metadata:
name: knative-serving
spec:
config:
network:
httpProtocol: "redirected"
...
10.2. HTTPS redirection per service
You can enable or disable HTTPS redirection for a service by configuring the networking.knative.dev/http-option annotation.
10.2.1. Redirecting HTTPS for a service
The following example shows how you can use this annotation in a Knative Service YAML object:
apiVersion: serving.knative.dev/v1
kind: Service
metadata:
name: example
namespace: default
annotations:
networking.knative.dev/http-protocol: "redirected"
spec:
...10.3. Full duplex support for HTTP/1
You can enable the HTTP/1 full duplex support for a service by configuring the features.knative.dev/http-full-duplex annotation.
Verify your HTTP clients before enabling, as earlier version clients might not provide support for HTTP/1 full duplex.
The following example shows how you can use this annotation in a Knative Service YAML object at the revision spec level:
Example KnativeServing CR that provides full duplex support for HTTP/1
apiVersion: serving.knative.dev/v1
kind: Service
metadata:
name: example-service
namespace: default
spec:
template:
metadata:
annotations:
features.knative.dev/http-full-duplex: "Enabled"
...
