Moving a running workload from one host to another transparently without disrupting its execution flow (“live migration”) is a solved problem for virtual machines, but still poses challenges for containers.

Current checkpoint and restore functionalities in both Kubernetes and LXD are somewhat limited or not completely fleshed out, and moving containers from one host to another involves either spinning up new replicas or stopping and restarting the containers, which is undesirable for stateful workloads like databases, machine learning or deep learning jobs.

Projects like CRIU (https://criu.org/Main_Page) and DMTCP (https://github.com/dmtcp/dmtcp) propose different approaches to offer checkpointing and restore functionalities in containers, but there is still no streamlined solution in LXD and Kubernetes.

In this lightning talk, we’ll go over the current state of the art, with a quick demo of what’s currently available, describing what’s missing and what will be the future developments to achieve seamless container live migration.
