bundle install --without-source gemfury
In some cases I don't want to install gems from my private gemfury. At the moment I found the best way to do so is with groups, but I wonder if the same can be done only by grouping gems by sources?
More specificaly on why I need this:
I want to build a docker image to which I pass gemfury credential by build argument, but that breaks layer caching with docker because everytime docker assumes it is the different gemfury cred passed via build arg.
