The Knative kn CLI enables simple interaction with Knative components on OKD.

You can enable Knative on OKD by installing OpenShift Serverless. For more information, see Getting started with OpenShift Serverless.

OpenShift Serverless cannot be installed using the kn CLI. A cluster administrator must install the OpenShift Serverless Operator and set up the Knative components, as described in the Serverless applications documentation for OKD.

Key features

The kn CLI is designed to make serverless computing tasks simple and concise. Key features of the kn CLI include:

  • Deploy serverless applications from the command line.

  • Manage features of Knative Serving, such as services, revisions, and traffic-splitting.

  • Create and manage Knative Eventing components, such as event sources and triggers.

  • Create sink bindings to connect existing Kubernetes applications and Knative services.

  • Extend the kn CLI with flexible plug-in architecture, similar to the kubectl CLI.

  • Configure autoscaling parameters for Knative services.

  • Scripted usage, such as waiting for the results of an operation, or deploying custom rollout and rollback strategies.
