Root Cause
Docker build fails in CI due to layer cache invalidation, missing build context files, or BuildKit cache backend issues. The build works locally but fails in CI where cache state differs.
genericWorkarounds
-
88% success Use GitHub Actions cache or registry-based cache for Docker layers
Use docker/build-push-action with 'cache-from: type=gha' and 'cache-to: type=gha,mode=max' to persist BuildKit layer cache between CI runs
-
90% success Fix .dockerignore and ensure build context contains all required files
Check that .dockerignore does not exclude files needed by COPY/ADD instructions. Verify the build context path matches the Dockerfile expectations. Use 'docker build --progress=plain' for verbose output
Dead Ends
Common approaches that don't work:
-
Disable Docker BuildKit to use the legacy builder
60% fail
Legacy builder is deprecated, slower, and lacks multi-stage build optimizations; does not fix the root cause of missing files or cache issues
-
Add --no-cache flag to every build in CI
50% fail
Disabling cache entirely makes builds significantly slower (10x+ in many cases) and wastes CI resources without addressing the underlying issue
