⁠Kafka Connect + JDBC Plugin

⁠Overview and purpose

The purpose is to have a clean, minimal and ready to use image for deploying Kafka Connect that already has the free JDBC connector plugins installed.
The image has been streamlined as much as possible (without being too aggressive) and is based on:

• The lastest official stable Busybox image⁠
• The official image for JRE binaries based on Alpine and built by Eclipse Temurin⁠. The latest available update of a long term Java version is chosen, which should be compliant if not exactly equivalent to the version deployed in the respective Confluent images.
• Confluent Platform Community Edition⁠'s tar.gz distribution
• Confluent JDBC Connector⁠ tar.gz distribution. Please refer to the official documentation and packages to know which database servers are supported; note that this image was made to specifically target Microsoft SQL Server.

⁠Parameters

The following environment parameters are supported:

• CONNECT_BOOTSTRAP_SERVERS (default "broker:29092")
• CONNECT_OFFSET_FLUSH_INTERVAL_MS (default 10000)
• CONNECT_CONVERTER_SCHEMA_REGISTRY_URL (default "http://schema-registry:8081")
• CONNECT_PORT (default "8083", it will listen on any address of the docker network on this port)
• CONNECT_GROUPID (default "connect-group")

In order to understand their meaning please refer to Confluent documentation.

⁠Versioning

The tag is derived from the Confluent package version plus the date of creation for versioning.
E.g. 7.9.0-20250425 is based on Confluent Community Edition 7.9.0 and was compiled on April 25th 2025.

⁠License

This software is free to use under the licenses for the respective components listed above.
