# Minimal Android Cast CI image (glibc-based; NDK prebuilts require linux-x86_64 glibc).
#
# Build:
#   docker build -t androidcast-ci:latest -f Dockerfile .
#
# Run CI build (mount repo):
#   docker run --rm -v "$(pwd)":/workspace -w /workspace androidcast-ci:latest
#
# Interactive:
#   docker run --rm -it -v "$(pwd)":/workspace -w /workspace androidcast-ci:latest bash
#
# Note: Alpine/musl breaks NDK clang prebuilts; use Debian slim instead of rust:* for size.
