Following the README, I get bundle errors like this:
$ docker run --rm -p 4000:4000 --mount type=bind,src=$PWD,dst=/root/build --mount type=volume,dst=/root/build/node_modules -it apache/privacy_apache_org serve --watch --incremental
Could not find concurrent-ruby-1.1.10 in any of the sources
Run `bundle install` to install missing gems.
Indeed it seems it has slightly different versions of those dependencies installed. How do I deal with that?
