Dockerfile

# Usage:
#
#   docker build -t bcryptjs-builder .
#   CONTAINER=$(docker create bcryptjs-builder)
#   # Then copy the artifact to your host:
#   docker cp "$CONTAINER:/usr/local/opt/bcrypt-js/prebuilds" .
#   docker rm "$CONTAINER"
#
# Use --platform to build cross-platform i.e. for ARM:
#
#   docker build -t bcryptjs-builder --platform "linux/arm64/v8" .
#   CONTAINER=$docker create --platform "linux/arm64/v8" bcryptjs-builder)
#   # this copies the prebuilds/linux-arm artifacts
#   docker cp "$CONTAINER:/usr/local/opt/bcrypt-js/prebuilds" .
#   docker rm "$CONTAINER"
