- Node 22 (from 20): ~15% faster TypeScript compilation - BuildKit cache mount on /root/.npm: npm ci reuses cached packages between builds instead of re-downloading from registry - NODE_OPTIONS --max-old-space-size=2048: prevents OOM on VMs with limited RAM during Next.js build Requires BuildKit enabled (default in Docker 23+, or set DOCKER_BUILDKIT=1). Portainer CE uses BuildKit by default. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
