For a list of filters or instance attributes consult the official documentation.

The Deployment Manifesto
The 10 Tenets of Deployments
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in
[RFC 2119](https://www.ietf.org/rfc/rfc2119.txt).
1. Configuration management MUST NOT be coupled to an external service, such as EC2, Openstack, Foreman, or anything else.
2. Devops SHOULD provide a self-service framework for the automatic creation and destruction of hosts from the ground up.
