# This node version is passed via --build-arg, but will be replaced
# after the FROM statement with the version specified in the image

FROM node:${NODE_VERSION}-alpine

# Need to declare the build args for use *after* the FROM statement
# NODE_VERSION is set in the alpine image already so we don't redeclare it
