When creating an instance it can be either a new instance or a read-only replica of an existing instance. This module has a dependency on python-boto >= 2.5. The 'promote' command requires boto >= 2.18.0. Certain features such as tags rely on boto.rds2 (boto >= 2.26.0) options: command: description: - Specifies the action to take. The 'reboot' option is available starting at version 2.0 required: true choices: [ 'create', 'replicate', 'delete', 'facts', 'modify' , 'promote', 'snapshot', 'reboot', 'restore' ] instance_name: description: - Database instance identifier. Required except when using command=facts or command=delete on just a snapshot required: false default: null source_instance: description: - Name of the database to replicate. Used only when command=replicate. required: false default: null db_engine: description: - The type of database.

If not specified then no database is created. Used only when command=create. required: false default: null engine_version: description: - Version number of the database engine to use. Used only when command=create. If not specified then the current Amazon RDS default engine version is used. required: false default: null parameter_group: description: - Name of the DB parameter group to associate with this instance. If omitted then the RDS default DBParameterGroup will be used.

Used only when command=create or command=replicate. - Prior to 2.0 it always defaults to null and the API would use 3306, it had to be set to other DB default values when not using MySql.
