Google Compute Engine Cookbook LWRP

Description

This cookbook provides libraries, resources and providers to configure
and manage Google Compute Enginge components. The currently supported
GCE resources are:

• disks (disk)
• firewalls (firewall)
• instances (instance)
• lb forwarding rules (lb_forwardingrule)
• lb health checks (lb_healthcheck)
• lb target pools (lb_targetpool)
• metadata (metadata)
• networks (network)
• snapshots (snapshot)
• tags (tags)

Requirements

Requires fog ruby gem to interact with GCP.

Authorizing Setup

In order to use the Google Compute Engine cookbook with your servers, you will first
need to authorize its use of the Google Compute Engine API. Authorization to use
any of Google's Cloud service API's utilizes an OAuth 2.0
Service account.
Once your project has been created, log in to the
Google Developers Console and
select your project. Next select APIs & auth then Credentials. Create a new
"Client ID" and specify "Service account". This will generate a new public/private key
pair.

    % knife data bag show gce service_account
    {
      "google_project_id": "my-gce-project",
      "google_client_email": "my-gce-project@developer.gserviceaccount.com",
      "google_key_location": "/home/user/.my-gce-project-private-key.p12"
    }

This can be loaded in a recipe with:

    gce = data_bag_item("gce", "service_account")

And to access the values:

    gce['google_project_id']
    gce['google_client_email']
    gce['google_key_location']

Installation

Download and install as you would other cookbooks.

From the Chef Community Site

knife cookbook site install gce

Using Librarian-Chef

Librarian-Chef Librarian is a framework
for writing bundlers, which are tools that resolve, fetch, install, and isolate a project's
dependencies, in Ruby.

To use the Opscode platform version:

    echo "cookbook 'gce'" >> Cheffile
    librarian-chef install

To use the Git version:

    echo "cookbook 'gce', :git => 'git@github.com:chef-partners/google-compute-engine.git'" >> Cheffile
    librarian-chef install

Recipes

default.rb

The default recipe installs the fog ruby gem, which this
cookbook requires in order to work with the GCE API. Make sure that
the google-compute-engine recipe is in the node or role run_list before any resources
from this cookbook are used.

    "run_list": [
      "recipe[google-compute-engine]"
    ]

Libraries

The cookbook has a library module, Google::Gce, which can be
included where necessary:

  include Google::Gce
