OS::Heat::MultipartMime

Assembles a collection of software configurations as a multi-part mime.

Parts in the message can be populated with inline configuration or references to other config resources. If the referenced resource is itself a valid multi-part mime message, that will be broken into parts and those parts appended to this message.

The resulting multi-part mime message will be stored by the configs API and can be referenced in properties such as OS::Nova::Server user_data.

This resource is generally used to build a list of cloud-init configuration elements including scripts and cloud-config. Since cloud-init is boot-only configuration, any changes to the definition will result in the replacement of all servers which reference it.
