Modify Serverless App

1. Modify code

Modify the function computeReward() section in bank-knative-service/index.js file. Modify the code so that it returns different points rewarded based on a category.

### index.js
function computeReward(category, amount) {
    if (category == "RIDE") {
        return 2 * amount
    }
    return amount;
}

2. Build and push container image

You can now build and push the container image with the updated code.

$ docker build -t $DOCKER_USERNAME/serverless-workshop-example:2.0 bank-knative-service
$ docker push $DOCKER_USERNAME/serverless-workshop-example:2.0

3. Modify deployment file

Modify the deployment file in bank-knative-service/deployment.yaml.

Make sure the image name is the one you built in the previous step.

      containers:
        - image: anthonyamanse/serverless-workshop-example:2.0

4. Deploy to OpenShift

You can now deploy the serverless app to openshift using oc apply

$ oc apply -f bank-knative-service/deployment.yaml

Verify its status. READY should be True

$ oc get ksvc
NAME                  URL                                                         LATESTCREATED               LATESTREADY                 READY   REASON
process-transaction   http://process-transaction.example-bank.svc.cluster.local   process-transaction-dh7kf   process-transaction-dh7kf   True

5. Test using the simulator again

$ oc get routes
NAME                       HOST/PORT             PATH   SERVICES                           PORT    TERMINATION   WILDCARD
mobile-simulator-service   ***.appdomain.cloud          mobile-simulator-service           <all>   edge          None
