US Patent 11436042 Migrating the runtime state of a container between two nodes

Embodiments of the present disclosure relate to migrating the in-memory state of a containerized application to a destination node. A processing device may identify a destination node on which a container currently running on a source node is to be migrated. The processing device may determine whether the destination node includes a replica of each base layer the container is comprised of, and may transmit a replica of each base layer the destination node is missing to the destination node. The processing device may halt the stream of data from the application to the client device, and transfer a replica of an in-memory layer of the container to the destination node so that the destination node further includes a second in-memory layer that is a replica of the in-memory layer.
