Field notes
The article lays out a pre-copy, freeze-and-commit, and restore sequence, and says errors before commit roll back. It describes a 2.7 MB wrapper around runc so the target pod can be restored without changing the node’s runtime stack. The page also gives kubectl examples for moving one pod or draining a node; the reported performance figures are presented as results from its demonstrations.
