Overview
A resource cleanup process that removes the Docker Buildx builder instance after image builds are complete.
Description
Builder Cleanup removes the dedicated Buildx builder instance that was created for multi-architecture builds. This frees system resources and build cache. In Kafka's workflow, cleanup is performed in a finally block to ensure the builder is removed even if the build fails.
Usage
Use this principle after all Docker image builds are complete, or in error handling paths to ensure resource cleanup.
Theoretical Basis
- Guaranteed Cleanup: Use finally/ensure patterns to guarantee builder removal regardless of build success or failure.
- Resource Release: Remove the builder to free up disk space used by build cache and intermediate layers.
