Chapter 1. About this tutorial

• Deploy a MySQL database server with a simple example database to OpenShift.
• Apply a custom resource in Streams for Apache Kafka to automatically build a Kafka Connect container image that includes the Debezium MySQL connector plug-in.
• Create the Debezium MySQL connector resource to capture changes in the database.
• Verify the connector deployment.
• View the change events that the connector emits to a Kafka topic from the database.

Prerequisites

• You are familiar with OpenShift and Streams for Apache Kafka.
• You have access to an OpenShift cluster on which the cluster Operator is installed.
• The Streams for Apache Kafka Operator is running.
• An Apache Kafka cluster is deployed as documented in Deploying and Managing Streams for Apache Kafka on OpenShift.
• You have a Red Hat build of Debezium license.
• You know how to use OpenShift administration tools. The OpenShift oc CLI client is installed or you have access to the OpenShift Container Platform web console.

• Depending on how you intend to store the Kafka Connect build image, you must either have permission to access a container registry, or you must create an ImageStream resource on OpenShift:

  To store the build image in an image registry, such as Red Hat Quay.io or Docker Hub

  • An account and permissions to create and manage images in the registry.

  To store the build image as a native OpenShift ImageStream

  • An ImageStream resource is deployed to the cluster for storing new container images. You must explicitly create an ImageStream for the cluster. ImageStreams are not available by default.
