Internal Function¶
Internal functions are used in a template to implement specific functions. For example, internal functions can be used to obtain external input parameters and attribute information about specified resources. Internal functions can only be used in the resources or outputs field.
Internal functions include get_attr, get_file, get_param, and get_resource. The internal functions supported by different template versions are different. For details, see Template Version. For syntax and examples of internal functions, see OpenStack Official Website.
