Abstract
Some embodiments provide a novel method for enforcing service policies at different container clusters configured by several SDN controller clusters. A first SDN controller cluster defines a particular service policy to be enforced for machines in first, second, and third container clusters. First, second, and third sets of network elements for the first, second, and third container clusters are managed by the first, a second, and a third SDN controller cluster respectively. For data message flows exchanged between machines in the first and second container clusters, the first SDN controller cluster distributes the particular service policy to service nodes only in the first container cluster. For data message flows exchanged between machines in the second and third container clusters, the first SDN controller cluster distributes the particular service policy to service nodes in at least one of the second and third container clusters.
