Line 135: − − === Coordinated checkpointing of distributed applications === − − '''Summary:''' Enable coordinated container checkpointing with Kubernetes. − − Checkpointing support has been recently introduced in Kubernetes, where the − smallest deployable unit is a Pod (a group of containers). Kubernetes is often − used to deploy applications that are distributed across multiple nodes. − However, checkpointing such distributed applications requires a coordination − mechanism to synchronize the checkpoint and restore operations. To address this − challenge, we have developed a new tool called <code>criu-coordinator</code> − that relies on the action-script functionality of CRIU to enable synchronization − in distributed environments. This project aims to extend this tool to enable − seamless integration with the checkpointing functionality of Kubernetes. − − '''Links:''' − * https://github.com/checkpoint-restore/criu-coordinator − * https://lpc.events/event/18/contributions/1803/ − * https://sched.co/1YeT4 − * https://kubernetes.io/blog/2022/12/05/forensic-container-checkpointing-alpha/ − − '''Details:''' − * Skill level: intermediate − * Language: Rust / Go / C − * Expected size: 350 hours − * Mentors: Radostin Stoyanov <rstoyanov@fedoraproject.org>, Prajwal S N <prajwalnadig21@gmail.com> − * Suggested by: Radostin Stoyanov <rstoyanov@fedoraproject.org>
