'Can I use Docker arguments in the `from` flag of a Docker COPY statement?
The following is the top of my Dockerfile:
ARG VERSION=dev
ARG DEPENDENCY_VERSION=latest
# Rebuild the source code only when needed
FROM node:14-alpine AS builder
ARG DEPENDENCY_VERSION
WORKDIR /app
COPY ./web .
COPY --from=registry.gitlab.com/my-group/my-project:${DEPENDENCY_VERSION} app/node_modules ./node_modules
The pipeline fails with an error error building image: could not parse reference. Am I messing something up or arguments are not allowed inside the --from flag?
