Configure auto-recovery and reinstall nodes
Reinstallation of all nodes in a group can be performed automatically via node auto-recovery — for all nodes in the cluster at once. You can reinstall one or more nodes manually.
Set up node auto-restore
If the cluster has only one working node, auto-recovery is not available.
Node auto-recovery will delete all data on the boot disk.
With auto-recovery enabled, working nodes will be automatically reinstalled if they do not respond to availability checks for about 15 minutes. During the recovery process, pods will stop running on the idle node and will be redistributed to other nodes. Autorecovery works for all nodes in the cluster at once.
You can enable node auto-recovery when cluster creation or for a created cluster.
- In Control Panel, go to Cloud Platform → Kubernetes.
- Open the cluster page → Settings tab.
- In the Automation block, enable Self-healing of nodes.
Reinstall nodes manually
You can reinstall each of the nodes manually.
When you reinstall node, all data on the boot disk will be deleted.
- In Control Panel, go to Cloud Platform → Kubernetes.
- Open the cluster page → Cluster Composition tab.
- From the menu ( ) of the node, select Reinstall.
