################################ Overview

# This Dockerfile builds a Label Studio environment.
# It consists of five main stages:
# 1. "frontend-builder" - Compiles the frontend assets using Node.
# 2. "frontend-version-generator" - Generates version files for frontend sources.
# 3. "venv-builder" - Prepares the virtualenv environment.
# 4. "py-version-generator" - Generates version files for python sources.
# 5. "prod" - Creates the final production image with the Label Studio, Nginx, and other dependencies.
