Why our im

[dust63]

I have been using the confluentinc/cp-server-connect Docker image (version 7.9.1) and noticed that the image size is quite large. Upon further inspection, I found that the image includes the OpenJDK, which might not be necessary for runtime purposes. Using a JRE instead of a JDK could significantly reduce the image size. The current image size is 3.5Go, i quite huge.

Observations:

1. Image Size:

   • The image size is quite large, making it less efficient for deployment in environments where smaller images are preferred.
   • This impacts pull times, storage requirements, and overall efficiency in CI/CD pipelines.

2. OpenJDK vs. JRE:

   • The image currently uses OpenJDK, which includes development tools that are not required for running Kafka Connect in production.
   • Switching to a JRE (Java Runtime Environment) would provide only the runtime components needed to execute Java applications, reducing the image size.

Questions:

1. Is there a specific reason for including the JDK instead of the JRE in the Docker image?
2. Are there plans to provide a slimmer version of the image, perhaps using a JRE or a minimal base image?

Thank you for your work on Kafka and for providing these Docker images. I look forward to your insights on this matter.

running Kafka Connect

You can take a look at my repo for just Kafka Connect dependencies rather than these images that pull all of confluent platform.

Other options include Strimzi or Debezium images, as well as Redpanda Connect depending on the use case.
