WARNING: The `gcloud preview app` surface is rapidly improving. Look out for
changing flags and new commands before the transition out of the `preview`
component. These changes will be documented in the Cloud SDK release notes
<https://goo.gl/X8apDJ> and via deprecation notices for changing commands.

If you would like to avoid changing behavior, please pin to a fixed version of
the Google Cloud SDK as described under the "Alternative Methods" section of the
Cloud SDK web site: <https://cloud.google.com/sdk/#alternative>.

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.
