Switched Node.js and Nginx images from 'bookworm' to 'alpine' variants to reduce image size. Added `apk upgrade --no-cache` for updated Alpine packages in the Nginx container. This optimizes resource usage and enhances performance.
Replaced alpine with bookworm-slim for Node.js and nginx to bookworm. This ensures compatibility with the latest updates and improves consistency across images. Adjusted the health check command for nginx accordingly.
