A policy type can be treated as the meta-type of a Policy object. A registry of policy types is built when the Cluster service starts. When creating a Policy object, you will indicate the policy type used in its spec property.
To examine the list of policies:
When listing policies, you can specify the sorting option using the sort
parameter and you can do pagination using the limit
and marker
parameters.
Full example: manage policy
When creating a policy, you will provide a dictionary with keys and values according to the policy type referenced.
Optionally, you can specify a metadata
keyword argument that contains some
key-value pairs to be associated with the policy.

After a policy is created, most of its properties are immutable. Still, you
can update a policy’s name
and/or metadata
.
The Cluster service doesn’t allow updating the spec
of a policy. The only
way to achieve that is to create a new policy.

A policy can be deleted after creation, provided that it is not referenced by any active clusters or nodes. If you attempt to delete a policy that is still in use, you will get an error message.
