## Root cause - Docker buildx memory options were incorrectly formatted - Database build during Docker image creation was failing on multi-platform builds - n8n native dependencies caused issues across different architectures ## Solution - Removed invalid buildx driver-opts configuration - Eliminated database build stage from Dockerfile - Now using pre-built nodes.db file (11MB) from repository - Fixed .dockerignore to include nodes.db in build context - Added .dockerignore to version control (was incorrectly gitignored) ## Benefits - Faster builds (no n8n package installation during build) - More reliable multi-platform builds (amd64 + arm64) - Simpler Dockerfile (3 stages instead of 4) Database can still be rebuilt locally using 'npm run rebuild' when needed. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
