• cf login -a <url> -u <student>
• at the prompt enter your student password

• cf create-user-provided-service cp -p cups.json (this will inject the Kakfa credentials at runtime)

• ./mvnw clean package -DskipTests (the tests will hang unless you are running kafka locally)

• cf push (just remember to be in the project root folder with the manifest.yml)

• cf logs stream (in another terminal)

• curl -X POST -d 'name=vik&age=33' https://<route>/user/publish (the will be the generated PCF route for pubsub cf app pubsub | grep routes)

Change the name and age in the payload and see if the stream filters it or not...
