Container checkpointing was introduced as an alpha feature in Kubernetes v1.25 and graduated to beta in Kubernetes v1.30. This functionality allows running containers to be transparently checkpointed to persistent storage and later restored to resume execution, or migrated across nodes and clusters.

 

The content of container checkpoints (memory pages, open files, network sockets, metadata) can be analyzed with the [https://github.com/checkpoint-restore/checkpointctl checkpointctl] tool.
