Demo showing scaling with Keda in OpenShift

This is a demo which deploys AMQ-Broker and OpenShift Custom Metrics Autoscaler based on KEDA

It establishes a broker with 2 queues q1 & q2 and scales a deployment. In this case the deployment is not related to the queue we are merely showing how keda behaves scaling a workload. The deployment used is pacman but this can be adjusted as required.

Once setup you can send a message to either queue via the Fuse broker console and the scaling will kick in.

To set up the demo

1. Install the AMQ Broker Operator

2. oc new-project keda-demo

3. Install the custom metrics Operator in the keda-demo project

4. Install the broker and queues

   oc project keda-demo

   oc apply -f https://raw.githubusercontent.com/bfarr-rh/keda-demo/master/yaml/amq-broker.yaml

5. Create the application

   oc new-app https://github.com/redhat-gpte-devopsautomation/pacman-1

6. Expose the application as a route and test Pacman runs

7. Create the Scaler Object

   oc apply -f https://raw.githubusercontent.com/bfarr-rh/keda-demo/master/yaml/keda.yaml

8. Navigate to the Fuse console (find the route) and login with admin/admin and use it to send and delete messages from either queue and watch the pods dynamically scale.
