Container Live Migration

on YouTube ↗39m

" summary

CRIU provides process-level checkpoint/restore that enables live container migration and is integrated into Podman, runc/crun, lxc/lxd, Borg, Docker and experimental cri-o/kubernetes support. Demos show kubernetes drain writing checkpoints to disk and restoring after reboot, podman creating checkpoint tar archives that include filesystem changes for easy transfer, and fast-start copies that start ~50% faster. Technical details cover injected parasite code to dump memory, kernel clone3 to reassign PIDs, and fixes for SElinux confinement to make restores work.
