# JellyTau Builder Image
# Pre-built image with all dependencies for building, testing, and packaging:
#   - Android APK (SDK/NDK), Linux desktop (deb/rpm),
#   - Windows cross via the official Tauri path: MSVC target + cargo-xwin + NSIS
# Arch packages build in a separate archlinux image (Dockerfile.arch) since
# makepkg is Arch-specific.
# Push to your registry: docker build -f Dockerfile.builder -t gitea.tourolle.paris/dtourolle/jellytau-builder:latest .

# Install Rust using rustup, pinned to an exact release.
#
# 🔴 RUST_VERSION must equal `channel` in src-tauri/rust-toolchain.toml.
#
# The two are a pair. rust-toolchain.toml is what makes a developer's `cargo
# clippy` agree with CI's; this line is what makes the image already contain that
# toolchain. If they drift, rustup silently downloads the pinned version the
# first time cargo runs inside a job — a toolchain install at job time, which
# CLAUDE.md's "🔴 CI installs no system tools" rule forbids (and which costs
# ~1min plus a network dependency on every build).
#
# 🔴 Changing this line does NOT change CI on its own: the image must be
# rebuilt and pushed (`scripts/build-builder-image.sh`) before the new pin is
# authoritative. Bump rust-toolchain.toml and this line together, rebuild, push,
# then merge.
#
# Was: `sh -s -- -y` (latest stable, whatever it happened to be on rebuild day).
