Install the current Bundler environment. By default, gems will be \
installed to the shared/bundle path. Gems in the development and \
test group will not be installed. The install command is executed \
with the --deployment and --quiet flags. If the bundle cmd cannot \
be found then you can override the bundle_cmd variable to specify \
which one it should use. The base path to the app is fetched from \
the :latest_release variable. Set it for custom deploy layouts.
You can override any of these defaults by setting the variables shown below.
N.B. bundle_roles must be defined before you require 'bundler/#{context_name}' \
in your deploy.rb file.
