Real time inventory demo GitOps

See Mkdocs book view to get demonstration script and installation.

This project can let you deploy the real-time inventory demonstration on OpenShift or run it locally on your laptop using docker compose. For OpenShift deployment you can

• Use an existing Event Streams deployed (multi-tenants) in cp4i-eventstreams namesspace, the topic is using a naming convention to avoid conflicting with other topics alreadt defined in this cluster.
• Use this repository to deploy a 3 broker cluster in the rt-inventory-dev namespace

To deploy you can use a pure GitOps approach using OpenShift GitOps or use make to deploy with oc CLI (See the Makefile under the root folder).

Be sure to clone this repository

git clone https://github.com/ibm-cloud-architecture/eda-rt-inventory-gitops.git

Run locally

• Start IBM Event Streams, IBM MQ, Kafka Connector, the Store Simulator App, the Item aggregator App, the Store aggregator App, and KafDrop to get a user interface to Kafka

cd local-demo/kstreams
docker-compose up -d

• Should have following docker containers running

docker ps
