Pull Request Overview

This PR reduces the cluster analytics runtime image size by switching from a custom base image (scenescape-common-base-24-04) to the official python:3.12-slim image and implementing a multi-stage build optimization strategy.

Key Changes:

• Replaced custom base image with python:3.12-slim for the runtime stage
• Reorganized dependency installation to use a virtual environment (/opt/venv) instead of system packages
• Streamlined system dependencies to only essential runtime libraries (libgl1, libglib2.0-0)

The healthcheck always returns success (true), making it ineffective. Replace with an actual health check that verifies the service is functioning correctly, such as checking if the application responds to requests or a specific health endpoint.

Suggested change

	HEALTHCHECK CMD true
	HEALTHCHECK CMD curl --fail --silent http://localhost:8000/health || exit 1

The Python version 3.12 is hardcoded in the path. Since the base image is python:3.12-slim, consider using a variable or dynamic path to make future Python version updates easier.
