1. A method of implementing service rules for a container cluster that is configured by a first software defined network (SDN) controller cluster, the method comprising:
registering for event notification from an application programming interface (API) server to receive notification regarding a set of events associated with resources deployed in the container cluster;
forwarding to a second SDN controller cluster a plurality of resource identifiers that are collected through the registration for a plurality of resources of the container cluster, the second SDN controller cluster defining service policies that are not defined by the first SDN controller cluster;
receiving, from the second SDN controller cluster, a set of service policies defined by the second SDN controller cluster based on the plurality of resource identifiers; and
distributing service rules defined based on the received set of service policies to network elements in the container cluster, said network elements enforcing the service rules on data messages associated with machines deployed in the container cluster configured by the first SDN controller cluster;
wherein the set of service policies is received by a set of one or more adapters residing in the container cluster and the set of one or more adapters forwards the set of service policies to a third SDN controller cluster that resides in the container cluster but does not configure the container cluster.
