Description
I have a base image nodebase for node apps which has
ONBUILD ADD package.json /tmp/package.json
ONBUILD RUN cd /tmp && npm install
ONBUILD RUN mkdir -p /app && cp -a /tmp/node_modules /app
I'd like to define an extension of it that includes postgres tools in the image. However, I don't want to have the "ONBUILDS" triggered in the extension -- rather they should be triggered in the "final" build with the app.
It would be nice to have
EXTEND nodebase
as a variant of from which supresses the "ONBUILD"s -- another Dockerfile built FROM the extension would then trigger them.
I see there are various proposals for "ONBUILD" floating around. Perhaps EXTEND would be a good place to control the staging of ONBUILDs, so that FROM could be kept simple.
