A step-by-step walkthrough of deploying the Debezium Platform on AWS using a single-node k3s cluster on EC2, then building a CDC pipeline from Amazon RDS for PostgreSQL to Amazon Kinesis. Key AWS-specific details covered include: enabling logical replication on RDS via a custom parameter group, creating Kinesis streams named to match Debezium topic names (schema: prefix.schema.table), and using an EC2 IAM instance role with a least-privilege policy for Kinesis authentication instead of static credentials. The companion project debezium-platform-lab automates cluster provisioning and Helm chart deployment with simple mage commands. The post also explains how to verify the pipeline by reading and decoding a change event from Kinesis, including how to handle PostgreSQL NUMERIC columns serialized as base64-encoded bytes.
