# NOTE FOR dynamo_base AND wheel_builder STAGES:
#
# All changes to dynamo_base and wheel_builder stages should be replicated across
# Dockerfile and Dockerfile.<framework> images.:
#   - Dockerfile
#   - Dockerfile.vllm
#   - Dockerfile.sglang
#   - Dockerfile.trtllm
# This duplication was introduced purposely to quickly enable Docker layer caching and
# deduplication. Please ensure these stages stay in sync until the duplication can be
# addressed.
#
# Throughout this file, we make certain paths group-writable because this allows
# both the dynamo user (UID 1000) and Dev Container users (UID != 1000) to work
# properly without needing slow chown -R operations (which can add 2-10 extra
# minutes).
#
# DEVELOPMENT PATHS THAT MUST BE GROUP-WRITABLE (for virtualenv containers):
#   /workspace            - Users create/modify project files
#   /home/dynamo          - Users create config/cache files
#   /opt/dynamo/venv      - TensorRT-LLM uses venv, so entire venv must be writable for pip install
#
# HOW TO ACHIEVE GROUP-WRITABLE PERMISSIONS:
# 1. SHELL + /etc/profile.d - Login shell sources umask 002 globally for all RUN commands (775/664)
# 2. COPY --chmod=775       - Sets permissions on copied children (not destination)
# 3. chmod g+w (no -R)      - Fixes destination dirs only (milliseconds vs minutes)

# This section contains build arguments that are common and shared with
# the plain Dockerfile, so they should NOT have a default. The source of truth is from build.sh.

# PURPOSE: Production runtime environment
#
# This stage creates a lightweight production-ready image containing:
# - Pre-compiled TensorRT-LLM 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 TensorRT-LLM
# - Minimal runtime footprint without build tools
# - Ready-to-run inference server environment
# - Base for custom application containers
