The OpenShift Serverless Operator and Knative Serving are installed.
You have logged in to the web console and are in the Administrator perspective.
Navigate to the Serverless → Serving page.
In the Create list, select Service.
Manually enter YAML or JSON definitions, or by dragging and dropping a file into the editor.
