Title:
APPLYING HYPERVISOR-BASED CONTAINERS TO A CLUSTER OF A CONTAINER ORCHESTRATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/046271
Kind Code:
A1
Abstract:
A computer-implemented method, system and computer program product for applying hypervisor-based containers to a cluster of a container orchestration system. A container runtime of a worker node in the cluster of the container orchestration system issues a request to create a sandbox environment to store a pod containing one or more containers. Upon creating the sandbox environment for each pod to improve isolation, a network tunnel is created between the worker node and the sandbox environment without packet encapsulation in which the sandbox environment shares the same Internet Protocol (IP) address as the other end of the network tunnel in the worker node. Packets may then be routed (forwarded) from the worker node to the sandbox environment via the network tunnel using source routing. By utilizing such source routing, packet looping is prevented. In this manner, hypervisor-based containers may be applied to a cluster of a container orchestration system.
