Vagrant Google Compute Engine (GCE) Provider

This is a Vagrant 1.2+ plugin that adds an Google Compute Engine (GCE) provider to Vagrant, allowing Vagrant to control and provision instances in GCE.

NOTE: This plugin requires Vagrant 1.2+,

Features

Boot Google Compute Engine instances.
SSH into the instances.
Provision the instances with any built-in Vagrant provisioner.
Minimal synced folder support via rsync.
Define zone-specific configurations so Vagrant can manage machines in multiple zones.

Usage

Install does not yet work using standard Vagrant 1.1+ plugin installation methods.
To install, clone and build the repo, and install from there. Something similar to the below

mkdir -p ~/tmp && cd ~/tmp
git clone https://github.com/mitchellh/vagrant-google
cd vagrant-google
bundle
rake build
cd ~

change out of the plugin source directory to avoid bundler issues

vagrant plugin install ~/tmp/vagrant-google/pkg/vagrant-google-0.1.2.gem

After installing, be sure to put a Vagrant.require_plugin "vagrant-google" at the top of your Vagrantfile so that Vagrant knows about the plugin.
vagrant up and specify the google provider. For example,

$ vagrant up --provider=google

Of course, prior to this you'll need to obtain a GCE-compatible box file for Vagrant.

Google Cloud Platform Setup

Prior to using this plugin, you will first need to make sure you have a Google Cloud Platform account, enable Google Compute Engine, and create a Service Account for API Access.

Log in with your Google Account and go to Google Cloud Platform and click on the Try it now button.
Create a new project and remember to record the Project ID you specify.
Next, visit the API Console, select Services and enable the Google Compute Engine service for your project. If prompted, review and agree to the terms of service.
While still in the API Console, go to API Access and click on the Create another client ID... button. In the pop-up dialog, select the Service Account radio button and the click the Create client ID button.
When prompted, select the Download private key button and make sure to save this file in a secure and reliable location. This key file will be used to authorize all Vagrant commands available in this plugin.
Still on the same page, find the newly created Service Account text block on the API Access page. Record the Email address associated with the new Service Account you just created. You will need this email address and the location of the private key file to properly configure this Vagrant plugin.

Quick Start

After installing the plugin (instructions above), the quickest way to get started is to actually use a dummy Google box and specify all the details manually within a config.vm.provider block. So first, add the Google box using any name you want:

$ vagrant box add gce https://github.com/mitchellh/vagrant-google/raw/master/google.box
...

And then make a Vagrantfile that looks like the following, filling in your information where necessary.

Vagrant.configure("2") do |config|
  config.vm.box = "gce"

  config.vm.provider :google do |google, override|
    google.google_project_id = "YOUR_GOOGLE_CLOUD_PROJECT_ID"
    google.google_client_email = "YOUR_SERVICE_ACCOUNT_EMAIL_ADDRESS"
    google.google_key_location = "/PATH/TO/YOUR/PRIVATE_KEY.p12"

    override.ssh.username = "USERNAME"
    override.ssh.private_key_path = "~/.ssh/id_rsa"
    #override.ssh.private_key_path = "~/.ssh/google_compute_engine"
  end

end

And then run vagrant up --provider=google.

This will start an Debian 7 (Wheezy) instance in the us-central1-a zone, with an n1-standard-1 machine, and the "default" network within your project. And assuming your SSH information was filled in properly within your Vagrantfile, SSH and provisioning will work as well.

Note that normally a lot of this boilerplate is encoded within the box file, but the box file used for the quick start, the "google" box, has no preconfigured defaults.

Box Format

Every provider in Vagrant must introduce a custom box format. This provider introduces google boxes. You can view an example box in the example_box/. That directory also contains instructions on how to build a box.

The box format is basically just the required metadata.json file along with a Vagrantfile that does default settings for the provider-specific configuration for this provider.

Configuration

This provider exposes quite a few provider-specific configuration options:

google_client_email - The Client Email address for your Service Account.
google_key_location - The location to the private key file matching your Service Account.
google_project_id - The Project ID for your Google Cloud Platform account.
image - The image name to use when booting your instance.
instance_ready_timeout - The number of seconds to wait for the instance to become "ready" in GCE. Defaults to 20 seconds.
machine_type - The machine type to use. The default is "n1-standard-1".
metadata - Custom key/value pairs of metadata to add to the instance.
name - The name of your instance. The default is "new".
network - The name of the network to use for the instance. Default is "default".
zone - The zone name where the instance will be created.

These can be set like typical provider-specific configuration:

Vagrant.configure("2") do |config|
  # ... other stuff

  config.vm.provider :google do |google|
    google.google_project_id = "my_project"
    google.google_client_email = "hashstring@example.com"
    google.google_key_location = "/tmp/private-key.p12"
  end
end

In addition to the above top-level configs, you can use the zone_config method to specify zone-specific overrides within your Vagrantfile. Note that the top-level zone config must always be specified to choose which zone you want to actually use, however. This looks like this:

Vagrant.configure("2") do |config|

  config.vm.box = "gce"

  config.vm.provider :google do |google|
    google.google_project_id = "my_project"
    google.google_client_email = "hashstring@example.com"
    google.google_key_location = "/tmp/private-key.p12"

    # Make sure to set this to trigger the zone_config
    google.zone = "us-central2-a"

    google.zone_config "us-central2-a" do |zone2a|
        zone2a.name = "testing-vagrant"
        zone2a.image = "debian-6-squeeze-v20130617"
        zone2a.machine_type = "n1-standard-4"
        zone2a.zone = "us-central2-a"
        zone2a.metadata = {'custom' => 'metadata', 'testing' => 'foobarbaz'}
    end
  end
end

The zone-specific configurations will override the top-level configurations when that zone is used. They otherwise inherit the top-level configurations, as you would probably expect.

There are a few example Vagrantfile's located in the vagrantfile_examples/ directory

Networks

Networking features in the form of config.vm.network are not supported with vagrant-google, currently. If any of these are specified, Vagrant will emit a warning, but will otherwise boot the GCE machine.

Synced Folders

There is minimal support for synced folders. Upon vagrant up, vagrant reload, and vagrant provision, the Google provider will use rsync (if available) to uni-directionally sync the folder to the remote machine over SSH.

This is good enough for all built-in Vagrant provisioners (shell, chef, and puppet) to work!

Known Issues

Can't boot from persistent disk - The underlying fog library does not currently support booting from a persistent disk.
No Tags - Tag support does not yet exist in the underlying fog library.

Development

To work on the vagrant-google plugin, clone this repository out, and use Bundler to get the dependencies:

$ bundle

Once you have the dependencies, verify the unit tests pass with rake:

$ bundle exec rake

If those pass, you're ready to start developing the plugin. You can test the plugin without installing it into your Vagrant environment by just creating a Vagrantfile in the top level of this directory (it is gitignored) that uses it, and uses bundler to execute Vagrant:

$ bundle exec vagrant up --provider=google
