Preface
This tutorial demonstrates how to use Debezium to capture updates in a MySQL database. As the data in the database changes, you can see the resulting event streams.
The tutorial includes the following steps:
- Deploy a MySQL database server with a simple example database to OpenShift.
- Apply a custom resource in AMQ Streams 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 AMQ Streams.
- You have access to an OpenShift cluster on which the cluster Operator is installed.
- The AMQ Streams Operator is running.
- An Apache Kafka cluster is deployed as documented in Deploying and Upgrading AMQ Streams on OpenShift.
- You have a Red Hat build of Debezium license.
-
You know how to use OpenShift administration tools. The OpenShift
ocCLI 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. You must explicitly create an ImageStream for the cluster. ImageStreams are not available by default.
Making open source more inclusive
Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.
