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.
