# Test image for the autopilot workspace.
#
# Mirrors the production target (Jetson Orin Nano Super, JetPack 6, Ubuntu
# 22.04 LTS aarch64, FFmpeg 4.4, OpenCV 4.8) — see deploy/jetson/README.md.
# `ffmpeg-sys-next 8.1` performs compile-time FFmpeg version detection
# (sets `ffmpeg_4_4` cfg automatically), so the workspace's `ffmpeg-next
# = "8.1"` pin works against Ubuntu 22.04's FFmpeg 4.4 with no code
# change.
#
# Build (on the Jetson):
#   docker build -t autopilot-test -f Dockerfile.test .
#
# Run (mount the source so `target/` is cached across runs):
#   docker run --rm -v "$PWD:/workspace" -w /workspace autopilot-test
#
# Override the command for ad-hoc work:
#   docker run --rm -it -v "$PWD:/workspace" -w /workspace autopilot-test \
#     cargo test --workspace --no-fail-fast --color always
#
# First build (cold apt + rustup): ~10-20 min on Jetson Orin Nano Super.
# Subsequent builds (only Cargo.toml / sources changed): seconds.

# this, the build panics with "a `libclang` shared library is not
