module: digital_ocean
short_description: Create/delete a droplet/SSH_key in DigitalOcean
description:
     - Create/delete a droplet in DigitalOcean and optionally wait for it to be 'running', or deploy an SSH key.
version_added: "1.3"
author: "Vincent Viallet (@zbal)"
options:
  command:
    description:
     - Which target you want to operate on.
    default: droplet
    choices: ['droplet', 'ssh']
  state:
    description:
     - Indicate desired state of the target.
    default: present
    choices: ['present', 'active', 'absent', 'deleted']
  api_token:
    description:
     - DigitalOcean api token.
    version_added: "1.9.5"
  id:
    description:
     - Numeric, the droplet id you want to operate on.
    aliases: ['droplet_id']
  name:
    description:
     - String, this is the name of the droplet - must be formatted by hostname rules, or the name of a SSH key.
  unique_name:
    description:
     - Bool, require unique hostnames.  By default, DigitalOcean allows multiple hosts with the same name.  Setting this to "yes" allows only one host
       per name.  Useful for idempotence.
    type: bool
    default: 'no'
    version_added: "1.4"
  size_id:
    description:
     - This is the slug of the size you would like the droplet created with.
  image_id:
    description:
     - This is the slug of the image you would like the droplet created with.
  region_id:
    description:
     - This is the slug of the region you would like your server to be created in.
  ssh_key_ids:
    description:
     - Optional, array of SSH key (numeric) ID that you would like to be added to the server.
  virtio:
    description:
     - "Bool, turn on virtio driver in droplet for improved network and storage I/O."
    type: bool
    default: 'yes'
    version_added: "1.4"
  private_networking:
    description:
     - "Bool, add an additional, private network interface to droplet for inter-droplet communication."
    type: bool
    default: 'no'
    version_added: "1.4"
  backups_enabled:
    description:
     - Optional, Boolean, enables backups for your droplet.
    type: bool
    default: 'no'
    version_added: "1.6"
  user_data:
    description:
      - opaque blob of data which is made available to the droplet
    version_added: "2.0"
  ipv6:
    description:
      - Optional, Boolean, enable IPv6 for your droplet.
    type: bool
    default: 'no'
    version_added: "2.2"
  wait:
    description:
     - Wait for the droplet to be in state 'running' before returning.  If wait is "no" an ip_address may not be returned.
    type: bool
    default: 'yes'
  wait_timeout:
    description:
     - How long before wait gives up, in seconds.
    default: 300
  ssh_pub_key:
    description:
     - The public SSH key you want to add to your account.

notes:
  - Two environment variables can be used, DO_API_KEY and DO_API_TOKEN. They both refer to the v2 token.
  - As of Ansible 1.9.5 and 2.0, Version 2 of the DigitalOcean API is used, this removes C(client_id) and C(api_key) options in favor of C(api_token).
  - If you are running Ansible 1.9.4 or earlier you might not be able to use the included version of this module as the API version used has been retired.
    Upgrade Ansible or, if unable to, try downloading the latest version of this module from github and putting it into a 'library' directory.
requirements:
  - "python >= 2.6"
  - dopy
