Template Variables

Template variables allow for workload descriptions to be parameterized outside the structure of the templating language.

Template variables are resolved in the workload after the on-disk format is loaded and before yaml parsing.

yaml:

name: <<myname,thedefault>>
desc: <<mydesc:mydescription>>

    "name": "UNSET:myname"
}
