From 72352bc53650dd54d4f6b7a2577ce3ef52f72a3c Mon Sep 17 00:00:00 2001 From: Leo Date: Wed, 6 May 2026 18:25:01 +0400 Subject: [PATCH] feat: implement multi-stage multi-arch Docker infrastructure (#758) - Refactored Dockerfile into builder and runtime stages for minimal image size. - Added support for linux/amd64 and linux/arm64 architectures with specific PyTorch handling. - Implemented virtual environment isolation and TA-Lib C library compilation. - Added docker-compose.yml for local development with persistent logging and secure .env mounts. - Synchronized requirements-docker.txt with enterprise production standards. - Optimized build performance with BuildKit cache mounts. - Enhanced security with non-root user execution.
