This topic describes the system labels and taints for nodes in a Volcengine Kubernetes Engine (VKE) cluster and how to manage them. When you customize labels or taints in VKE, avoid conflict with system labels or taints.
System labels in VKE
Label Key | Description |
Label Key | Description |
cluster.vke.volcengine.com/cluster-name | Cluster ID. |
cluster.vke.volcengine.com/machine-name | Node ID. |
cluster.vke.volcengine.com/machinepool-name | The node pool ID. |
cluster.vke.volcengine.com/machinepool-type | Node pool types. |
cluster.vke.volcengine.com/node-name | Node metadata name (metadata.name). |
machine.cluster.vke.volcengine.com/gpu-name | Graphics card name. |
cluster.vke.volcengine.com/hpc-cluster-id | ID of the high-performance compute cluster associated with the VKE cluster. |
cluster.vke.volcengine.com/affinity-group-id | ID of the affinity group associated with the VKE node pool. |
tip
In addition to the labels listed above, all other labels that contain vke.volcengine.com are system labels.

System taints in VKE
Taint Key | Description |
Taint Key | Description |
vke.volcengine.com/node-initializing:NoSchedule | This taint is related to node initialization when an existing node is added, and it is automatically removed after the node is added. |
node.willDelete:NoSchedule | The taints used when deleting and draining a node. |
ToBeDeletedByClusterAutoscaler | This is a scale-in taint added by Cluster Autoscaler (CA). After the taint is added successfully, node draining starts, and the node is deleted by the Auto Scaling group after draining is completed. |
DeletionCandidateOfClusterAutoscaler | This taint is added by CA before scale-in to make the node less likely to receive scheduled pods. |
