Overview

Package policy describes a generic interface for retrieving policies. Different implementations are possible for environments such as Kubernetes, Mesos or other custom environments. An implementation has to provide a method for retrieving policy based on the metadata associated with the container and deleting the policy when the container dies. It is up to the implementation to decide how to generate the policy. The package also defines the basic data structure for communicating policy information. The implementations are responsible for providing all the necessary data.
