Reference documentation and code samples for the Google Cloud OS Config v1 API class OSPolicyAssignment.
OS policy assignment is an API resource that is used to
apply a set of OS policies to a dynamically targeted group of Compute Engine
VM instances.
An OS policy is used to define the desired state configuration for a
Compute Engine VM instance through a set of configuration resources that
provide capabilities such as installing or removing software packages, or
executing a script.
public OSPolicyAssignment.Types.Rollout Rollout { get; set; }
Required. Rollout to deploy the OS policy assignment.
A rollout is triggered in the following situations:
1) OSPolicyAssignment is created.
2) OSPolicyAssignment is updated and the update contains changes to one of
the following fields:
