I’m running into a problem trying to use the RDS module to modify an existing RDS instance.

When running this command (attempting to modify the instance from db.t2.small to db.t2.medium):

ansible-playbook rds.yml -e “command=modify application=soa db\_admin\_user=\*\*\*\*\*\* db\_admin\_user\_pwd='_ **’ env=dev instance\_name=** instance\_type=db.t2.medium iops=1000 read\_only\_replica=false size=200 subnet=_\*\*\*\*\*\* vpc\_security\_groups=\*\*\*\*\*\*\*”

I get the following error:

TASK: [rds | rds] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

failed: [localhost] =\> {“failed”: true}

msg: Both storage size and iops need to be specified when modifying storage size or iops on an DB Instance that has iops

Here’s what the play looks like for a modify:
