# 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.
# The upstream runtime images may ship CUDA apt sources that occasionally go out of sync (mirror updates),
# causing apt-get update to fail with "File has unexpected size ... Mirror sync in progress".
# 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.
# Estimated layer size: ~800MB–1.0GB (build-essential+clang ~500MB, the rest ~300MB)
# Cache apt downloads; sharing=locked avoids apt/dpkg races with concurrent builds.
