Installing Knative

There are three installation methods to install Knative:

• A quickstart experience on a local computer only by using a preconfigured extension.
• A YAML installation suitable for production use.
• A Knative Operator installation suitable for production use.

A Knative installation is composed of the Serving and Eventing components. The quickstart implements both. The YAML and Knative Operator installations provide options to install either or both.

Supported platforms are Linux, MacOS, and Windows.
