Constraint class

A Constraint describes a way in which a resource's configuration can be restricted. For example, it controls which cloud services can be activated across an organization, or whether a Compute Engine instance can have serial port connections established. Constraints can be configured by the organization's policy adminstrator to fit the needs of the organzation by setting Policies for Constraints at different locations in the organization's resource hierarchy. Policies are inherited down the resource hierarchy from higher levels, but can also be overridden. For details about the inheritance rules please read about Policies.

Constraints have a default behavior determined by the constraint_default field, which is the enforcement behavior that is used in the absence of a Policy being defined or inherited for the resource in question.
