Docker Build Failed? ContextZip Keeps the Context That Matters

ContextZip is a tool that compresses verbose Docker build output by stripping cached layers and noise, preserving only error-relevant lines. In a demo case, it reduced a 120-line failed Docker build log to just the critical TypeScript error and failure status, achieving an 89% character reduction. It recognizes Docker-specific patterns, distinguishing signal (ERROR lines, Dockerfile references) from noise (CACHED lines, layer hashes).
