Abstract: Some embodiments provide a novel method for resiliently associating Internet Protocol (IP) addresses with pods that each have unique identifiers (IDs) in a managed cluster of worker nodes managed by a first set of one or more controllers of the managed cluster. The resilient association between IP addresses and pods is maintained even when pods are moved between worker nodes. At a second set of controllers, the method receives notification regarding deployment, on a first worker node, of a stateful pod associated with a particular ID. The method allocates an IP address to the stateful pod. The method creates a mapping between the IP address and the particular ID in order to maintain the allocation of the IP address to the stateful pod. The method provides the IP address to the first set of controllers to use for the stateful pod.
