# BikeControl builder image.
#
# One image that can do every job CI asks of it:
#   - `cargo test` / `clippy` on the host target, which means the *Linux BLE*
#     stack must be present: btleplug talks to BlueZ over D-Bus, so libdbus is a
#     hard build dependency, not an optional extra.
#   - the Tauri desktop bundle (deb / AppImage), which needs the webkit2gtk set.
#   - the Android APK: SDK, NDK, JDK, and the three Android Rust targets.
#
# Build and push:
#   docker build -f Dockerfile.builder -t gitea.tourolle.paris/dtourolle/bikecontrol-builder:latest .
#   docker push gitea.tourolle.paris/dtourolle/bikecontrol-builder:latest
# or run scripts/build-builder-image.sh.
