Abstract
The present invention relates to methods and apparatus for migrating and/or changing the allocation of network interface(s) or Internet Protocol address(es) of network interface(s) from one Pod, e.g., a failed Pod, to another Pod, e.g., a live Pod, in a Kubernetes system. An exemplary method of operating a Kubernetes system in accordance with an embodiment of the invention includes: establishing, by the Kubernetes system, a first service including a first Pod located on a first node and a second Pod located on a second node, allocating by the Kubernetes system an external network interface including an Internet Protocol address for use by the first Pod, the allocation of said external network interface for use by the first Pod being unknown to a first Kubelet managing the first node; and upon failure of the first Pod, changing allocation of the external network interface from the first Pod to the second Pod.
