DigitalOcean Vagrant Provider

vagrant-digitalocean is a Vagrant provider plugin that supports the management of DigitalOcean Droplets (virtual machines).

Features include:

• Create and destroy Droplets
• Power on and off Droplets
• Rebuild a Droplet (destroys and ups with same IP address)
• Provision a Droplet with shell
• Setup a SSH public key for authentication
• Create a new user account during Droplet creation

Install the provider plugin using the Vagrant command-line interface:

vagrant plugin install vagrant-digitalocean

Once the provider has been installed, you will need to configure your project to use it. See the following example for a basic multi-machine Vagrantfile implementation that manages two DigitalOcean Droplets running Ubuntu 18.04 using a single CPU Droplet with 1GB of memory:

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

  config.vm.define "droplet1" do |config|
      config.vm.provider :digital_ocean do |provider, override|
        override.ssh.private_key_path = '~/.ssh/id_rsa'
        override.vm.box = 'digital_ocean'
        override.vm.box_url = "https://github.com/devopsgroup-io/vagrant-digitalocean/raw/master/box/digital_ocean.box"
        override.nfs.functional = false
        override.vm.allowed_synced_folder_types = :rsync
        provider.token = 'YOUR TOKEN'
        provider.image = 'ubuntu-18-04-x64'
        provider.region = 'nyc1'
        provider.size = 's-1vcpu-1gb'
        provider.backups_enabled = false
        provider.private_networking = false
        provider.ipv6 = false
        provider.monitoring = false
      end
  end

  config.vm.define "droplet2" do |config|

      config.vm.provider :digital_ocean do |provider, override|
        override.ssh.private_key_path = '~/.ssh/id_rsa'
        override.vm.box = 'digital_ocean'
        override.vm.box_url = "https://github.com/devopsgroup-io/vagrant-digitalocean/raw/master/box/digital_ocean.box"
        override.nfs.functional = false
        override.vm.allowed_synced_folder_types = :rsync
        provider.token = 'YOUR TOKEN'
        provider.image = 'ubuntu-18-04-x64'
        provider.region = 'nyc3'
        provider.size = 's-1vcpu-1gb'
        provider.backups_enabled = false
        provider.private_networking = false
        provider.ipv6 = false
        provider.monitoring = false
      end
  end

end

Configuration Requirements

• You must specify the override.ssh.private_key_path to enable authentication with the Droplet. The provider will create a new DigitalOcean SSH key using your public key which is assumed to be the private_key_path with a .pub extension.
• You must specify your DigitalOcean Personal Access Token at provider.token. This may be found on the control panel within the Apps & API section.

Supported Configuration Attributes

The following attributes are available to further configure the provider:

• provider.image
  • A string representing the image to use when creating a new Droplet. It defaults to ubuntu-18-04-x64. List available images with the vagrant digitalocean-list images $DIGITAL_OCEAN_TOKEN command. Like when using the DigitalOcean API directly, it can be an image ID or slug.
• provider.ipv6
  • A boolean flag indicating whether to enable IPv6
• provider.region
  • A string representing the region to create the new Droplet in. It defaults to nyc2. List available regions with the vagrant digitalocean-list regions $DIGITAL_OCEAN_TOKEN command.
• provider.size
  • A string representing the size to use when creating a new Droplet (e.g. s-1vcpu-1gb). It defaults to s-1vcpu-1gb. List available sizes with the vagrant digitalocean-list sizes $DIGITAL_OCEAN_TOKEN command.
• provider.private_networking
  • A boolean flag indicating whether to enable a private network interface (if the region supports private networking). It defaults to false.
• provider.backups_enabled
  • A boolean flag indicating whether to enable backups for the Droplet. It defaults to false.
• provider.ssh_key_name
  • A string representing the name to use when creating a DigitalOcean SSH key for Droplet authentication. It defaults to Vagrant.
• provider.setup
  • A boolean flag indicating whether to setup a new user account and modify sudo to disable tty requirement. It defaults to true. If you are using a tool like Packer to create reusable snapshots with user accounts already provisioned, set to false.
• provider.monitoring
  • A boolean indicating whether to install the DigitalOcean agent for monitoring. It defaults to false.
• provider.tags
  • A flat array of tag names as strings to apply to the Droplet after it is created. Tag names can either be existing or new tags.
• provider.volumes
  • A flat array including the unique identifier for each Block Storage volume attached to the Droplet.
• config.vm.synced_folder
  • Supports both rsync__args and rsync__exclude, see the Vagrant Docs for more information. rsync__args default to ["--verbose", "--archive", "--delete", "-z", "--copy-links"] and rsync__exclude defaults to [".vagrant/"].

The provider will create a new user account with the specified SSH key for authorization if config.ssh.username is set and the provider.setup attribute is true.

After creating your project's Vagrantfile with the required configuration attributes described above, you may create a new Droplet with the following command:

$ vagrant up --provider=digital_ocean

This command will create a new Droplet, setup your SSH key for authentication, create a new user account, and run the provisioners you have configured.

Supported Commands

The provider supports the following Vagrant sub-commands:

• vagrant destroy - Destroys the Droplet instance.
• vagrant ssh - Logs into the Droplet instance using the configured user account.
• vagrant halt - Powers off the Droplet instance.
• vagrant provision - Runs the configured provisioners and rsyncs any specified config.vm.synced_folder.
• vagrant reload - Reboots the Droplet instance.
• vagrant rebuild - Destroys the Droplet instance and recreates it with the same IP address which was previously assigned.
• vagrant status - Outputs the status (active, off, not created) for the Droplet instance.

This DigitalOcean API provider plugin for Vagrant has been tested with the following technology.

Before submitting a GitHub issue, please ensure both Vagrant and vagrant-digitalocean are fully up-to-date.

• For the latest Vagrant version, please visit the Vagrant website

• To update Vagrant plugins, run the following command: vagrant plugin update

• vagrant plugin install vagrant-digitalocean

  • Installation on OS X may not working due to a SSL certificate problem, and you may need to specify a certificate path explicitly. To do so, run ruby -ropenssl -e "p OpenSSL::X509::DEFAULT_CERT_FILE". Then, add the following environment variable to your .bash_profile script and source it: export SSL_CERT_FILE=/usr/local/etc/openssl/cert.pem.

• The Chef provisioner is no longer supported by default (as of 0.2.0). Please use the vagrant-omnibus plugin to install Chef on Vagrant-managed machines. This plugin provides control over the specific version of Chef to install.

To contribute, fork then clone the repository, and then the following:

Releasing

To release a new version of vagrant-digitalocean you will need to do the following:

(only contributors of the GitHub repo and owners of the project at RubyGems will have rights to do this)

1. First, bump, commit, and push the version in ~/lib/vagrant-digitalocean/version.rb:
   • Follow Semantic Versioning.
2. Then, create a matching GitHub Release (this will also create a tag):
   • Preface the version number with a v.
   • https://github.com/devopsgroup-io/vagrant-digitalocean/releases
3. You will then need to build and push the new gem to RubyGems:
   • rake gem:build
   • gem push pkg/vagrant-digitalocean-0.7.6.gem
4. Then, when John Doe runs the following, they will receive the updated vagrant-digitalocean plugin:
   • vagrant plugin update
   • vagrant plugin update vagrant-digitalocean
