I have a Dockerfile that change file permissions to various folders, one of that is a node_modules

RUN chown -R 0:0 .                                                                                                                                                   
RUN chmod a+rX -R -c .

And this takes time!

I was wondering if I could use a tmpfs partition to build, and instruct docker to use it, because I have a lot of RAM, and RAM is fast.

Is it possible?

  • @Community the idea in question is simple: use tmpfs for all image building to speed things up but to save the final image as usual. I have the same question
