Although container migration is always viewed as an outlier or corner case of containers, because containers are supposed to be stateless, CRIU continues to get better at container migration and even if containers are supposed to be stateless, CRIU still sees growing interest in its container migration features and especially the integration in container runtimes. This talk wants to present the multiple use cases for checkpointing and restoring containers. The talk wants to give a technical background how CRIU is enabling container runtimes to checkpoint and restore containers and the plan how to integrate checkpoint and restore into Kubernetes.
