ENV SUMMARY="Minimal image for running Node.js $NODEJS_VERSION applications" \
    DESCRIPTION="Node.js $NODEJS_VERSION available as container is a base platform for \
running various Node.js $NODEJS_VERSION applications and frameworks. \
Node.js is a platform built on Chrome's JavaScript runtime for easily building \
fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model \
that makes it lightweight and efficient, perfect for data-intensive real-time applications \
that run across distributed devices." \
