clouder criu

CRIU checkpoint operations, visibility, and storage configuration helpers.

Runtime checkpoint lifecycle commands (checkpoint, restore, ls, inspect, delete) call the runtimes API.

Set these environment variables (or pass --run-url / --api-key):

export DATALAYER_RUN_URL=https://prod1.datalayer.run
export DATALAYER_API_KEY=<your-api-key>

Tab completion notes:

• --cluster suggestions come from ~/.clouder/kubeadm/*/kubeadm.json
• --key suggestions come from local private keys in ~/.ssh/
