使rvm gemset镜像/参考Capistrano的捆绑包安装

Question

I'm currently deploying from my local machine to a development server using Capistrano. The dev server has a gemset for my project called 'vcc', but as is clear across the internet, Capistrano does its bundle install into shared/bundle rather than the rvm gemset.

It's easy enough to make a .rvmrc file and have that selecting the 'vcc' gemset when I cd into the project. However, this gemset doesn't get updated as part of a deploy. So I still generally run all my commands with 'bundle exec', which selects the 'shared/bundle' rather than the rvm gemset.

What I want to do is have the rvm gemset remain updated so that when I cd into the project I don't have to run bundle exec before everything. I'm not sure what the best way to do this is. My only idea was to create a symlink in the 'vcc' gemset directory that points to the 'shared/bundle' directory. I read somehwere that rvm should be self contained though and will not follow symlinks out of the /rvm directory?

I've seen that it's possible to make Capistrano deploy to your gemset, but it's not recommended. I'm fine with letting Capistrano handle gems and rvm handle ruby, I just want to get rid of "bundle exec." Maybe there's an easier way that doesn't have anything to do with configuring Capistrano or rvm?

Actually it is not recommended to use vendored gems, there are few issues with it and you will be safer using a gemset instead.

rvm-capistrano already suggests you disable the vendored gems here https://github.com/wayneeseguin/rvm-capistrano#disabling-bundle---deployment-when-using-gemsets :

set :bundle_dir, ''
set :bundle_flags, '--system --quiet'

This way gems will be installed in gemset and everything will work fine.
