Getting Started With DigitalOcean¶

DigitalOcean is a public cloud host that specializes in Linux instances.

Configuration¶

Using Salt for DigitalOcean requires a personal_access_token, an ssh_key_file, and at least one SSH key name in ssh_key_names. More ssh_key_names can be added by separating each key with a comma. The personal_access_token can be found in the DigitalOcean web interface in the "Apps & API" section. The SSH key name can be found under the "SSH Keys" section.

# Note: This example is for /etc/salt/cloud.providers or any file in the
# /etc/salt/cloud.providers.d/ directory.

my-digitalocean-config:
  driver: digitalocean
  personal_access_token: xxx
  ssh_key_file: /path/to/ssh/key/file
  ssh_key_names: my-key-name,my-key-name-2
  location: New York 1

Note

Changed in version 2015.8.0.

The provider parameter in cloud provider definitions was renamed to driver. This change was made to avoid confusion with the provider parameter that is used in cloud profile definitions. Cloud provider definitions now use driver to refer to the Salt cloud module that provides the underlying functionality to connect to a cloud host, while cloud profiles continue to use provider to refer to provider configurations that you define.

Profiles¶

Cloud Profiles¶

Set up an initial profile at /etc/salt/cloud.profiles or in the /etc/salt/cloud.profiles.d/ directory:

digitalocean-ubuntu:
  provider: my-digitalocean-config
  image: 14.04 x64
  size: 512MB
  location: New York 1
  private_networking: True
  backups_enabled: True
  ipv6: True
  create_dns_record: True
  userdata_file: /etc/salt/cloud.userdata.d/setup
  tags:
    - tag1
    - tag2
    - tag3

Locations can be obtained using the --list-locations option for the salt-cloud command:

# salt-cloud --list-locations my-digitalocean-config
my-digitalocean-config:
    ----------
    digitalocean:
        ----------
        Amsterdam 1:
            ----------
            available:
                False
            features:
                [u'backups']
            name:
                Amsterdam 1
            sizes:
                []
            slug:
                ams1
...SNIP...

Sizes can be obtained using the --list-sizes option for the salt-cloud command:

# salt-cloud --list-sizes my-digitalocean-config
my-digitalocean-config:
    ----------
    digitalocean:
        ----------
        512MB:
            ----------
            cost_per_hour:
                0.00744
            cost_per_month:
                5.0
            cpu:
                1
            disk:
                20
            id:
                66
            memory:
                512
            name:
                512MB
            slug:
                None
...SNIP...

Images can be obtained using the --list-images option for the salt-cloud command:

# salt-cloud --list-images my-digitalocean-config
my-digitalocean-config:
    ----------
    digitalocean:
        ----------
        10.1:
            ----------
            created_at:
                2015-01-20T20:04:34Z
            distribution:
                FreeBSD
            id:
                10144573
            min_disk_size:
                20
            name:
                10.1
            public:
                True
...SNIP...

Profile Specifics:¶

ssh_username¶

If using a FreeBSD image from DigitalOcean, you'll need to set the ssh_username setting to freebsd in your profile configuration.

digitalocean-freebsd:
  provider: my-digitalocean-config
  image: 10.2
  size: 512MB
  ssh_username: freebsd

userdata_file¶

New in version 2016.11.6.

Use userdata_file to specify the userdata file to upload for use with cloud-init if available.

my-openstack-config:
  # Pass userdata to the instance to be created
  userdata_file: /etc/salt/cloud-init/packages.yml

my-do-config:
  # Pass userdata to the instance to be created
  userdata_file: /etc/salt/cloud-init/packages.yml
  userdata_template: jinja

If no userdata_template is set in the cloud profile, then the master configuration will be checked for a userdata_template value. If this is not set, then no templating will be performed on the userdata_file.

To disable templating in a cloud profile when a userdata_template has been set in the master configuration file, simply set userdata_template to False in the cloud profile:

my-do-config:
  # Pass userdata to the instance to be created
  userdata_file: /etc/salt/cloud-init/packages.yml
  userdata_template: False

Miscellaneous Information¶

Note

DigitalOcean's concept of Applications is nothing more than a pre-configured instance (same as a normal Droplet). You will find examples such Docker 0.7 Ubuntu 13.04 x64 and Wordpress on Ubuntu 12.10 when using the --list-images option. These names can be used just like the rest of the standard instances when specifying an image in the cloud profile configuration.

Note

If your domain's DNS is managed with DigitalOcean, and your minion name matches your DigitalOcean managed DNS domain, you can automatically create A and AAA records for newly created droplets. Use create_dns_record: True in your config to enable this. Adding delete_dns_record: True to also delete records when a droplet is destroyed is optional. Due to limitations in salt-cloud design, the destroy code does not have access to the VM config data. WHETHER YOU ADD create_dns_record: True OR NOT, salt-cloud WILL attempt to delete your DNS records if the minion name matches. This will prevent advertising any recycled IP addresses for destroyed minions.

Note

If you need to perform the bootstrap using the local interface for droplets, this can be done by setting ssh_interface: private in your config. By default the salt-cloud script would run on the public interface however if firewall is preventing the connection to the Droplet over the public interface you might need to set this option to connect via private interface. Also, to use this feature private_networking: True must be set in the config.
