# PURPOSE: Framework development and SGLang compilation
#
# This stage builds and compiles framework dependencies including:
# - SGLang inference engine with CUDA support
# - All necessary build tools and compilation dependencies
# - Framework-level Python packages and extensions
#
# Use this stage when you need to:
# - Build SGLang from source with custom modifications
# - Develop or debug framework-level components
# - Create custom builds with specific optimization flags
#

# Use dynamo base image (see /container/Dockerfile for more details)

# PURPOSE: Production runtime environment
#
# This stage creates a lightweight production-ready image containing:
# - Pre-compiled SGLang and framework dependencies
# - Dynamo runtime libraries and Python packages
# - Essential runtime dependencies and configurations
# - Optimized for inference workloads and deployment
#
# Use this stage when you need:
# - Production deployment of Dynamo with SGLang
# - Minimal runtime footprint without build tools
# - Ready-to-run inference server environment
# - Base for custom application containers
