  name:
    description:
      - Name of the databases server instance
  flavor:
    description:
      - flavor to use for the instance 1 to 6 (i.e. 512MB to 16GB)
    default: 1
  volume:
    description:
      - Volume size of the database 1-150GB
    default: 2
  cdb_type:
    description:

    aliases: ['type']
  cdb_version:
    description:
      - version of database (MySQL supports 5.1 and 5.6, MariaDB supports 10, Percona supports 5.6)
    choices: ['5.1', '5.6', '10']

      - wait for the instance to be in state 'running' before returning
    type: bool
    default: 'no'
