Reset a node

Last Updated: Dec 04, 2017

You can reset a node in a cluster. The system disk of the corresponding machine (the reset node) is replaced and the data stored in the system disk is lost. The reset machine is re-added to the cluster.


  • Resetting an Elastic Compute Service (ECS) instance changes the ECS system disk. The disk ID is changed and the previous system disk is released.
  • The reset ECS instance is restored to the status when it was added to the cluster.
  • All data is cleaned up when resetting the node.
  • Back up your data before resetting the node to avoid data loss.


  1. Log on to the Container Service console.

  2. Click Nodes in the left-side navigation pane.

  3. Select the cluster where the node you want to reset resides from the Cluster list.

  4. Click More at the right of the node you want to reset and then select Reset from the list.


  5. In the confirmation window, enter the instance logon password, and click Confirm.
