Overview
A validation process that builds and tests Docker images locally before publishing to a container registry.
Description
Docker Build Testing constructs a Docker image from the Kafka binary distribution and runs a suite of sanity tests to verify the image works correctly. The process supports both JVM and native (GraalVM) image types. It creates a temporary build context, copies necessary Dockerfiles and configurations, builds the image, then runs automated tests that generate an HTML report.
Usage
Use this principle before any Docker image release. Local build testing catches issues early, before pushing potentially broken images to a public registry.
Theoretical Basis
- Build Context Preparation: Create a temporary directory with Dockerfile, resources, and Kafka binary.
- Image Build: Execute docker build with the appropriate Dockerfile for the image type.
- Test Execution: Run the test suite against the built image to verify functionality.
- Report Generation: Produce an HTML test report for review.
