**Updated for: OpenShift Local 2.35.0 (OpenShift 4.15.10)
This repository illustrates using Red Hat technology together with .NET application code in a simple eventing example. The demo is designed to run on OpenShift. The main components used by this demo are:
- 3Scale API Management
- AMQ Streams (Kafka)
- OpenShift Serverless (knative)
- Knative Kafka and Kafka Source (knative)
- Microsoft SQL Server (containerized)
Additionally a containerized web-based SQL client called CloudBeaver is used to introspect the state of the SQL Server instance.
The application code is represented by two services, a producer service (Kafka-prod) used to place a message on AMQ Streams, and a consumer service (Kafka-con) to receive the message as a CloudEvent. Kafka-con also runs in serverless which allows the service to spin down to zero instances when not needed. This component architecture can be visualized as below.
This repository is organized as follows:
The top level folders organize the categories of content. For instance apps contains any application source code, scripts contains any scripted logic, yaml contains OpenShift/kubernetes resource definitions. The final folder at this level is zip_files. Due to github restrictions on large files some dependent content will need to be added after you clone the repository. The zip_files folder contains a script to distribute this content to the appropriate locations.
Taking a closer look at the scripts folder, the second level folders are demo and deploy. The demo folder contains resources for running the demo, while the deploy folder contains resources for setting up the environment.
