Node Label and Taint Check

Check Items

  • Check whether custom node labels are lost.
  • Check whether there are any unexpected taints newly added on the node, which will affect workload scheduling.

Procedure

  1. Log in to the CCE console and click the cluster name to access the cluster console.
  2. In the navigation pane, choose Nodes. On the displayed page, click the Nodes tab, select all nodes, and click Labels and Taints to view the labels and taints of the current node.

Solution

Custom labels will not be changed during a cluster upgrade. If you find that labels are lost or added unexpectedly, contact technical support.

If you find a new taint (node.kubernetes.io/upgrade) on a node, the node may be skipped during the upgrade. For details, see Node Skipping Check.

If you find that other taints are added to the node, contact technical support.
