Automated Multi-Stage Docker Build for Complex Python Microservices

Design a multi-stage Dockerfile that builds a complex Python microservice using Poetry for dependency management, with separate stages for development, testing, and production. The solution must include multi-architecture support (amd64 and arm64), Alpine Linux base image optimization, and automatic dependency vulnerability scanning. Include a comprehensive CI/CD pipeline configuration that performs static code analysis, runs comprehensive pytest suites, and generates both container image and SBOM (Software Bill of Materials).
