In this post, I'll share how you can get your own Event Endpoint Management demo instance with just seven minutes of work.
(Seven minutes of hands-on-keyboard time... there is a lot of waiting-for-stuff-to-run time, but it doesn't sound so impressive if I include waiting time!)
The best way to learn about something new is to get hands-on and play with it.
With something like Event Endpoint Management, to start kicking the tyres you need something to put in it. It starts getting interesting to play with once you have a few streams of events to publish and manage with it. You can really start to see the developer experience that it enables once you have a developer portal populated with a variety of real event sources.
But setting all of that up (creating a Kafka cluster, creating a bunch of Kafka topics, starting applications to produce messages to those topics, writing documentation describing the schemas of those messages, creating Kafka credentials and configuring the gateway with them, etc.) takes a little effort.
The idea of giving you this "demo in a box" is to do all of that for you, so you can dive straight in to playing with it - with hardly any up-front effort.
Before I jump into showing you how to set it up for yourself, let me show you what you'll get.
Under the covers, the demo script:
I'll go through what you need to do step by step. For each step, I've recorded a video of me doing it.
They are very boring videos - there isn't any audio, so you're spared any more of my voice for these bits. And I didn't want to speed them up, so you can see exactly how long it takes!
I haven't included time to get the pre-requisites that I'm hoping you'll already have:
oc
, git
, make
If you need to go get any of those, then this will take you a little longer than seven minutes, sorry! Hopefully not much longer though.
By the way - I know you'll see a bunch of my passwords and API keys in the videos, but don't worry on my behalf - the cluster I used for the demo has been deleted, and I've revoked all the credentials that you'll see.

pre-requisites: | somewhere to create an OpenShift cluster! |
You need somewhere to run the demo!
I used TechZone to reserve a demo cluster on the managed Red Hat OpenShift service on IBM Cloud (ROKS).
video recording at youtu.be/pol7hXxC2is
When everything is up and running, this is how full my cluster was:
You can tell I was a bit over-generous with the size of the cluster I reserved!
You probably won't get a cluster instantly, so now is a good time to go get yourself a coffee!
I've chosen storage classes to use assuming that you'll run this on ROKS as well. But if you're running OpenShift somewhere else, you'll likely want to choose your own storage class names.
To choose the storage classes used by the Cloud Pak for Integration components installed, edit the cp4i-overrides.yaml
file before you start the demo deployment.
apiVersion: v1 kind: ConfigMap metadata: name: cp4i-overrides namespace: pipeline-eventdrivendemo type: kubernetes.io/basic-auth data: ibm-common-service-operator-storageClassName: ibmc-file-gold-gid ibm-integration-platform-navigator-storageClassName: ibmc-file-gold-gid ibm-eventstreams-storageClassName: ibmc-file-gold-gid ibm-apiconnect-storageClassName: ibmc-block-gold
To choose the storage classes used by the demo deployment pipelines, edit the values identified by: find . -name 'pipelinerun*yaml' -print0 | sort -z | xargs -0 grep storageClassName
$ find . -name 'pipelinerun*yaml' -print0 | sort -z | xargs -0 grep storageClassName ./02-install-ibm-catalog/pipelinerun.yaml: storageClassName: ibmc-block-gold ./03-install-ibm-common-services/pipelinerun.yaml: storageClassName: ibmc-block-gold ./04-install-platform-navigator/pipelinerun.yaml: storageClassName: ibmc-block-gold ./05-install-event-streams/pipelinerun.yaml: storageClassName: ibmc-block-gold ./06-start-kafka-connectors/pipelinerun.yaml: storageClassName: ibmc-block-gold ./07-install-event-endpoint-management/pipelinerun-install.yaml: storageClassName: ibmc-block-gold ./07-install-event-endpoint-management/pipelinerun-setup.yaml: storageClassName: ibmc-block-gold ./08-publish-topics-to-eem/pipelinerun.yaml: storageClassName: ibmc-block-gold ./08-publish-topics-to-eem/pipelinerun.yaml: storageClassName: ibmc-block-gold
(hands-on-keyboard) time: | 40 seconds |
pre-requisites: | oc , make |
You've got the demo automation, you've collected the credentials you need, and you've got an OpenShift cluster.
It's time to start the demo deployment.

(hands-on-keyboard) time: | none! |
This is going to take a while.
Sorry - the demo setup script could really do with parallelising some steps! I went more with simplicity than efficiency. (Pull requests are welcome!)
The deployment script only outputs which step it is up to.

If you go to the Pipelines page in the OpenShift console, you'll also see how far it has got.
You'll also have access to the detailed logs for each step.
Try to resist keep checking though.
You don't need to do anything in this step!
It won't go any faster if you keep watching it!
The last thing the demo deployment script does is print out the URLs and username/password for each of the demo components.
Make a note of them.
If you lose them, you can generate this again by running make output_details

If you want to get rid of all the resources associated with the deployment pipelines, you can run make clean
. (This doesn't remove any of the actual demo itself, just the automation used to deploy it)
Use the URLs and usernames/passwords in the output to access some of the UIs deployed by the demo.
The following videos give you an idea of what you can expect to see. (These ones do include audio, sorry!)
Event Streams
This is the UI that the owner of the Kafka cluster would use. You can see all of the topics that the demo comes with:
video recording at youtu.be/5YPYKQHmc60
Event Endpoint Management (API Manager)
This is the UI that someone would use to document and publish their Kafka topics.
An "Events demo" catalog is pre-created for you, with an Event Gateway and Developer Portal set up and ready for use.
All of the demo Event Streams topics are documented in the API catalog using AsyncAPI.
The Event Gateway is configured for use with the topics, using custom Kafka credentials and SSL certificates generated for each topic.
video recording at youtu.be/5YPYKQHmc60
Event Endpoint Management (Developer Portal)
This is the UI that someone would use to discover the Kafka topics that are available within their organisation for them to use in their applications.
All of the demo Event Streams topics are published in the Developer Portal, with documentation describing where the data comes from and the schema of the messages.
The Portal helps developers to use the topics they discover, with generated code for creating new applications, and configuration properties for existing applications.
video recording at youtu.be/5YPYKQHmc60
You can try using the Developer Portal to create your own client application.
The Developer Portal provides a self-service way to create credentials for your application. You just need to log on first, using the credentials in the demo setup output.
There are some resources with the demo to help you do this. This is particularly useful if you've not written a Kafka application before.
01-get-jars.sh
02-download-truststore.sh
SampleApplication.java
03-compile-sample.sh
04-run-sample.sh
video recording at youtu.be/5YPYKQHmc60
This is a long post, but I hope this doesn't put you off giving it a try.
You just need to create a few credentials, and then run a single command. And I think trying out an instance of Event Endpoint Management that is populated with real live Kafka topics with real messages on them is the best way to get you thinking about how you could use it for real.
