# Unified development image with two targets:
# - dev: Root-based development for use with run.sh
# - local-dev: Non-root development with UID/GID remapping for Dev Container plugin
#
# IMPORTANT (concat model):
# This Dockerfile is intended to be used via the temp concatenated Dockerfile flow in
# `container/build.sh` (which prepends the selected framework Dockerfile):
#   - container/Dockerfile
#   - container/Dockerfile.vllm
#   - container/Dockerfile.trtllm
#   - container/Dockerfile.sglang
#
# The concatenated file provides the stages this Dockerfile depends on:
#   - `dynamo_base`   (framework base stage; used for cached tool binaries like maturin)
#   - `wheel_builder` (framework wheel_builder stage; used for cached Rust/Cargo and SGLang NIXL deps)
#
# Dependency graph (concat flow):
#
#   container/build.sh concatenates:
#     [framework Dockerfile] + [this file]
#
#   Framework Dockerfile (examples: Dockerfile.vllm / Dockerfile.trtllm / Dockerfile.sglang)
#   defines these stages (names matter; this file refers to them by name):
#
#     dynamo_base  (FROM ${BASE_IMAGE}:${BASE_IMAGE_TAG})
#        ├─ wheel_builder (FROM quay.io/pypa/manylinux_2_28_*)
#        ├─ framework     (builds framework install + /opt/dynamo/venv, etc.)
#        └─ runtime       (FROM ${RUNTIME_IMAGE}:${RUNTIME_IMAGE_TAG}; copies from dynamo_base/wheel_builder/framework)
#             └─ dev      (root dev image; adds dev-time linking config and pulls in tooling from dynamo_tools)
#                  └─ local-dev (non-root dev image with UID/GID remapping)
#
#   Side stage used by `dev`:
#
#     dynamo_tools (FROM runtime; installs extra developer utilities that `dev` copies in)
#
# Both targets share:
# - Developer utilities and tools from dynamo-tools
# - Rust toolchain + maturin for editable installs (from concatenated framework stages)
# - NIXL dependencies for SGLang (from concatenated framework wheel_builder stage)
#
# Note on build args:
# - `ARCH` / `ARCH_ALT` are declared in the prepended framework Dockerfile; we re-declare them only
#   in stages where they are used (Docker requires ARG re-declare per-stage).


# ======================================================================
# STAGE: dynamo_tools for developers
# ======================================================================
# Why this is a separate stage (not merged into `dev`):
# - `dev` is built FROM the framework `runtime` image. Installing lots of tooling with apt in that stage is slow and
#   makes rebuilds expensive when iterating on later dev layers.
# - Keeping tooling installation in `dynamo_tools` lets Docker cache the tools layer independently; `dev` can then
#   pull those binaries/configs in via COPY.

# NOTE: We intentionally disable the NVIDIA CUDA apt repo for this stage.

# This stage only installs generic developer tools that are available from Ubuntu repos, so CUDA repos are unnecessary.
#
# We also add a small retry/backoff to make transient apt metadata issues less disruptive.
