This demo scenario for showcasing the strangler fig pattern requires access to a Kubernetes cluster. In case you neither have any locally available k8s environment on your development machine (e.g. minikube) nor a Kubernetes cluster playground at your disposal you can can claim your personal, managed OpenShift Developer Sandbox free of charge for 30 days by registering your personal account at Red Hat - NO(!) credit card or any other payment means necessary to do so 😎
Make sure to login / authenticate to the Kubernetes cluster you want to use for running this demo scenario.
Also verify that your kubectl is properly configured and points to the cluster in question.
In the root directory of the repo you find a bash script which is named run-sfp-demo.sh. Run this script to execute all the demo steps one by one. The script stops/breaks after each important step: continue execution by pressing ENTER.
At certain stages of the demo script, kafka topics are consumed. The consumer process keeps listening for new records - stop the consumer by hitting CTRL+C once you inspected the records in the terminal in order to proceed with the following demo steps.
