Stateful container migration

Abstract:

A computer-implemented method for migrating a source container with a running application to a target container may be provided. The method includes providing a source container motion daemon being executed in the source container management system, and a target container motion daemon being executed in the target container management system, and creating a host container hosting an encapsulated container environment in the target container management system. The host container is executing a host container motion daemon and the target container. The method also includes connecting a container motion controller to the source container motion daemon, the target container motion daemon and the host container motion daemon, and copying content of a source memory of the source container to a target memory via the source container motion daemon and the host container motion daemon under control of the container motion controller.
