问题
I have a server that is totally disconnected from the Internet (for some strange security reasons).
How can I make the Ruby dependencies to various gems work in that environment? It might work with Bundler, but how do I install Bundler using gem without a Internet connection?
回答1:
You can download bundler as a .gem file from rubygems and install it on the server with
gem install /path/to/bundler.gem
Then you can pack all gems required for your application into ./vendor/cache directory with
bundle package
If now you deploy your app (along with ./vendor/cache directory) to the server and run
bundle install --local
bundler won't go to rubygems, but instead will install all gems from ./vendor/cache directory.
See bundler-package docs for more information.
