What is the Kubernetes Checkpoint/Restore Working Group?

It's a new community group integrating CRIU checkpoint/restore into Kubernetes for fault-tolerant, migratable pods — targeting AI, long-running apps, and more.

How does CRIU work with Kubernetes?

CRIU snapshots running containers transparently; tools like checkpoint-restore-operator manage it via K8s APIs, enabling preemption and migration without app changes.

When will checkpoint/restore land in Kubernetes?

No firm date — WG discusses KEPs now. Expect pilots in 2026, core features by 2027 if momentum holds.
