Vagrant OpenStack Cloud Provider

This is a Vagrant 1.1+ plugin that adds a OpenStack Cloud provider to Vagrant, allowing Vagrant to control and provision machines within an OpenStack cloud.

This plugin started as a fork of the Vagrant RackSpace provider.

Note: This plugin requires Vagrant 1.1+.

Features

  • Boot OpenStack Cloud instances.
  • SSH into the instances.
  • Provision the instances with any built-in Vagrant provisioner.
  • Minimal synced folder support via rsync.

Usage

Install using standard Vagrant 1.1+ plugin installation methods. After installing, vagrant up and specify the openstack provider. An example is shown below.

$ vagrant plugin install vagrant-openstack-plugin
...
$ vagrant up --provider=openstack
...

Of course prior to doing this, you'll need to obtain an OpenStack-compatible box file for Vagrant.

Quick Start

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

$ vagrant box add dummy https://github.com/cloudbau/vagrant-openstack-plugin/raw/master/dummy.box
...

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

require 'vagrant-openstack-plugin'

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

  # Make sure the private key from the key pair is provided
  config.ssh.private_key_path = "~/.ssh/id_rsa"

  config.vm.provider :openstack do |os|    # e.g.
    os.username = "YOUR USERNAME"          # "#{ENV['OS_USERNAME']}"
    os.api_key  = "YOUR API KEY"           # "#{ENV['OS_PASSWORD']}" 
    os.flavor   = /m1.tiny/
    os.image    = /Ubuntu/
    os.endpoint = "KEYSTONE AUTH URL"      # "#{ENV['OS_AUTH_URL']}/tokens"  
    os.keypair_name = "YOUR KEYPAIR NAME"
    os.ssh_username = "SSH USERNAME"
    os.metadata = {"key" => "value"}       # Optional
    os.network = "YOUR NETWORK_NAME"       # Optional
    os.address_id = "YOUR ADDRESS ID"      # Optional (`network` above has higher precedence)
    os.scheduler_hints = {
        :cell => 'australia'
    }                                      # Optional
    os.availability_zone = "az0001"        # Optional
    os.security_groups = ['ssh', 'http']   # Optional
    os.tenant = "YOUR TENANT_NAME"         # Optional
    os.floating_ip = "33.33.33.33"         # Optional (The floating IP to assign for this instance)
  end
end

And then run vagrant up --provider=openstack.

This will start a tiny Ubuntu instance in your OpenStack installation within your tenant. 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 "dummy" box, has no preconfigured defaults.

Box Format

Every provider in Vagrant must introduce a custom box format. This provider introduces openstack boxes. You can view an example box in the example_box/ directory. 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:

  • api_key - The API key for accessing OpenStack.
  • flavor - The server flavor to boot. This can be a string matching the exact ID or name of the server, or this can be a regular expression to partially match some server flavor.
  • image - The server image to boot. This can be a string matching the exact ID or name of the image, or this can be a regular expression to partially match some image.
  • endpoint - The keystone authentication URL of your OpenStack installation.
  • server_name - The name of the server within the OpenStack Cloud. This defaults to the name of the Vagrant machine (via config.vm.define), but can be overridden with this.
  • username - The username with which to access OpenStack.
  • keypair_name - The name of the keypair to access the machine.
  • ssh_username - The username to access the machine. This can also be configured using the standard config.ssh.username configuration value.
  • metadata - A set of key pair values that will be passed to the instance for configuration.
  • network - A name or id that will be used to fetch network configuration data when configuring the instance. NOTE: This is not compliant with the vagrant network configurations.
  • address_id - A specific address identifier to use when connecting to the instance. network has higher precedence.
  • scheduler_hints - Pass hints to the open stack scheduler, see --hint flag in OpenStack filters doc
  • availability_zone - Specify the availability zone in which the instance must be created.
  • security_groups - List of security groups to be applied to the machine.
  • tenant - Tenant name. You only need to specify this if your OpenStack user has access to multiple tenants.

These can be set like typical provider-specific configuration:

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

  config.vm.provider :openstack do |rs|
    rs.username = "mitchellh"
    rs.api_key  = "foobarbaz"
  end
end

Networks

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

Synced Folders

There is minimal support for synced folders. Upon vagrant up, vagrant reload, and vagrant provision, the OpenStack 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!

Development

To work on the vagrant-openstack-plugin 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=openstack
