Should the following Dockerfile produce an error when invoked via
docker build -f Dockerfile . --no-cache? I think there are two reasons that it should – (a) no value for ARG_NO_DEFAULT and (b) COPY requires 2 args, but has (actually) none.
I’m probably missing something! Thx for any advice.
FROM postgres:latest ARG ARG_NO_DEFAULT COPY $ARG_NO_DEFAULT $ARG_NO_DEFAULT
