Explore the current state and future of container live migration in this 13-minute lightning talk from the Linux Foundation's Open Source Summit. Examine the challenges of moving running containerized workloads between hosts without disrupting execution, contrasting the mature virtual machine live migration solutions with the limitations facing containers today. Discover how current checkpoint and restore functionalities in Kubernetes and LXD fall short of seamless migration requirements, particularly for stateful workloads such as databases and machine learning jobs. Learn about existing projects like CRIU and DMTCP that offer different approaches to container checkpointing and restoration, while understanding why no streamlined solution exists yet in major container orchestration platforms. Watch a demonstration of currently available migration capabilities and gain insights into the technical gaps that need addressing and future developments required to achieve true seamless container live migration across different hosts.
