Elastic Beanstalk Ruby/Rails need to install git so bundle install works.. but is not

cfernandezlinux picture cfernandezlinux · Nov 30, 2012 · Viewed 18.4k times · Source

I'm having an issue deploying our rails app.. I created a hook like the example on the AWS blog howto http://ruby.awsblog.com/post/Tx2AK2MFX0QHRIO/Deploying-Ruby-Applications-to-AWS-Elastic-Beanstalk-with-Git like:

packages:
  yum:
    git: []

even I run a bundle package to create vendor/cache to have all the gems there... and still getting: git://github.com/refinery/refinerycms-search.git (at 2-0-stable) is not checked out. Please run bundle install (Bundler::GitError)

any help will be nice, we trying to move all our apps to EB. but seens that git does not install or something is going on.. I need git on the EB ec2 instance it creates.

StackTrace:

Error message:
git://github.com/refinery/refinerycms-search.git (at 2-0-stable) is not checked out.         Please run `bundle install` (Bundler::GitError)

UPDATE more info: I decided to log into the instance with ec2-user and notice that git is installed the gems I need ARE installed so far I can see.. when I do bundle list they all show up even the one that the error is complaining about.. I do notice that when I do a general gem list then it DOES not show up... but it should be using the bundle one.

(Note that the following workaround should only be used if you must use Git sources for dependencies. It is recommended not to install dependencies from external Git repositories if it can be avoided. See below for details on why that is.)

When using Git backed libraries in a Gemfile with Passenger, you must disable shared gems in an installation (in addition to installing Git in the hook you listed above). You can do this by setting the BUNDLE_DISABLE_SHARED_GEMS Bundler environment variable in your existing .ebextensions/ruby.config file like so:

option_settings:
  - option_name: BUNDLE_DISABLE_SHARED_GEMS
    value: "1"
  - option_name: BUNDLE_PATH
    value: "vendor/bundle"

packages:
  yum:
    git: []

Disabling shared gems will force all dependencies to be vendored into your application in vendor/bundle as specified by the BUNDLE_PATH variable.

Note that, whenever possible, you should avoid installing public libraries from Git sources with your application. Using Git for library locations introduces another point of failure for a deployment install, since the Git repository may be temporarily unavailable or even permanently moved. Also keep in mind that forcing vendored installs in a deployment will cause your Elastic Beanstalk deployments to be much slower on subsequent deploys of an app with the same dependencies. This is because the libraries will be re-installed at each deploy instead of taking advantage of the system-wide installation that Elastic Beanstalk has Bundler perform by default.

In short, if there is an official RubyGem release of the library in question, you should use that version instead; and if not, you should suggest to the library author that an official RubyGem release be made available.

FYI a similar question about this Git problem with regular Passenger/Rails deployments was previously asked: Rails 3: Passenger can't find git gems installed by bundler
