Hi,

According to the documentation for the aws\_ec2 plugin, the compose option can be used to create vars when the plugin is executed.

I’ve been trying to get this to work with a simple plugin config like so:

plugin: aws\_ec2  
regions:

- us-east-1  
filters:  
tag:Environment: prod  
instance-state-name: running  
hostnames:
- private-ip-address  
compose:  
site: ‘testing’  
strict\_permissions: False  
strict: False

However, when I run a playbook and supply the above inventory file, the ‘site’ var is undefined.

Am I using this option correctly?

Thanks,  
Guy

Does anyone have any suggestions about this?
