1.1.1.1 Tosca Policy Type Definitions
...
In addition, the Policy Type has the following recognized keynames:
Keyname | Required | Type | Description |
properties | no | list of | An optional list of property definitions for the Policy Type. |
targets |
no | string[] | An optional list of valid Node Types or Group Types the Policy Type can be applied to. |
Note: This can be viewed by TOSCA Orchestrators as an implied relationship to the target nodes, but one that does not have operational lifecycle considerations. For example, if we were to name this as an explicit Relationship Type we might call this “AppliesTo” (node or group). | |||
triggers | no | list of trigger | An optional list of policy triggers for the Policy Type. |
1.1.1.1.2 Grammar
Policy Types have the following grammar:
