Serverless applications

modules/common-attributes.adoc :context: serverless-applications

To deploy a serverless application using {ServerlessProductName}, you must create a Knative service. Knative services are Kubernetes services, defined by a route and a configuration, and contained in a YAML file.

Example Knative service YAML

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!"

The name of the application.
The namespace the application uses.
The image of the application.
The environment variable printed out by the sample application.

Create a Knative service from the {product-title} web console. See the documentation about Creating applications using the Developer perspective.
