module: rax_keypair
short_description: Create a keypair for use with Rackspace Cloud Servers
description:
     - Create a keypair for use with Rackspace Cloud Servers
version_added: 1.5
options:
  name:
    description:
      - Name of keypair
    required: true
  public_key:
    description:
      - Public Key string to upload. Can be a file path or string
    default: null
  state:
    description:
      - Indicate desired state of the resource
    choices:
      - present
      - absent
    default: present
author: Matt Martz
notes:
  - Keypairs cannot be manipulated, only created and deleted. To "update" a
    keypair you must first delete and then recreate.
  - The ability to specify a file path for the public key was added in 1.7
