Serverless applications are created and deployed as Kubernetes services, defined by a route and a configuration, and contained in a YAML file. To deploy a serverless application using {ServerlessProductName}, you must create a Knative Service object.

Example Knative Service object YAML file
apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: hello (1)
  namespace: default (2)
spec:
  template:
    spec:
      containers:
        - image: docker.io/openshift/hello-openshift (3)
          env:
            - name: RESPONSE (4)
              value: "Hello Serverless!"

  1. The name of the application.

  2. The namespace the application uses.

  3. The image of the application.

  4. The environment variable printed out by the sample application.
