Overview

Package meta defines framework constants used as keys in k8s annotations that are attached to k8s pods. The scheduler uses some of these annotations for reconciliation upon failover. Other annotations are used as part of the host-to-pod port-mapping implementation understood by the k8s-mesos scheduler and custom endpoints-controller implementation.
