Switched to Chainguard images as base for both CPU and CUDA backend builds for improved security and compatibility. Replaced Ubuntu base with Chainguard's Python image for the CPU builds and PyTorch CUDA image for GPU acceleration, resolving python requirements conflicts. Updated package installation commands to align with the new Redhat-compatible base images. The Dockerfile now installs only the necessary dependencies, as Python is provided by the base image.
These changes will facilitate a more secure and streamlined build process with better dependency management across different platforms.
Standardized CUDA_VERSION as a global ARG to ensure consistency and facilitate version updates across the Dockerfile. This change allows the CUDA version to be defined once at the beginning and reused, reducing the chance of mismatched versions and easing maintenance when changing CUDA versions. It further streamlines the build process for potential multi-stage builds with varying CUDA dependencies.

Refactored the Dockerfile to better organize and streamline environment variable settings, emphasizing support for a CUDA-based WebUI backend while retaining the ability to build a CPU-only image. Consolidated ENV commands to reduce layers, improving build efficiency, and set a default PORT environment to enhance container usability. Enabled exposure of the backend service on port 8080 and leveraged combined RUN directives to minimize the image footprint. These changes facilitate a more robust deployment process, catering to both CPU and CUDA environments.
