Installing Knative Eventing

After you install the OpenShift Serverless Operator, you can install Knative Eventing by following the procedures described in this guide.

Knative Eventing is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see https://access.redhat.com/support/offerings/techpreview/.

This guide provides information about installing Knative Eventing using the default settings.
