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 source_instance: description: - Name of the database to replicate. Used only when command=replicate. db_engine: description: - The type of database. Used only when command=create. - mariadb was added in version 2.2 choices: ['mariadb', 'MySQL', 'oracle-se1', 'oracle-se2', 'oracle-se', 'oracle-ee', 'sqlserver-ee', 'sqlserver-se', 'sqlserver-ex', 'sqlserver-web', 'postgres', 'aurora'] size: description: - Size in gigabytes of the initial storage for the DB instance.
