Declaring and managing dependencies
Dependencies for Ruby applications are declared in a standard
file. For example:
source "https://rubygems.org" gem "rails"
You can use any Linux-compatible Ruby package in the App Engine flexible environment, including packages that require native (C) extensions.
The Ruby runtime will automatically install all dependencies
declared in your
Gemfile during deployment.
Installing a web framework
You'll need to use a web framework to enable your app to serve web requests. You can use any Ruby web framework including the following:
To use a particular web framework, specify a startup command in your
runtime: ruby env: flex entrypoint: rails server
Installing the Google Cloud Client library
The Google Cloud Client Library for Ruby is a client library for accessing Google Cloud Platform services that significantly reduces the boilerplate code you have to write. The library provides high-level API abstractions so they're easier to understand and means you spend more time creating code that matters to you.
To install the library locally:
gem install google-cloud
The client library can automatically handle authentication for you locally as well by using the Google Cloud SDK:
gcloud auth login
