Generated Worker Node Name Formats

Find out about the format of the names that Kubernetes Engine (OKE) gives to worker nodes in the clusters it creates.

Regardless of how you create a cluster, Kubernetes Engine gives names to worker nodes. The format depends on the type of node:

• Managed nodes: Names have the following format:

  oke-c<part-of-cluster-OCID>-n<part-of-node-pool-OCID>-s<part-of-subnet-OCID>-<slot>

  where:

  • oke is the standard prefix for all worker nodes created by Kubernetes Engine
  • c<part-of-cluster-OCID> is a portion of the cluster's OCID, prefixed with the letter c
  • n<part-of-node-pool-OCID> is a portion of the node pool's OCID, prefixed with the letter n
  • s<part-of-subnet-OCID> is a portion of the subnet's OCID, prefixed with the letter s
  • <slot> is an ordinal number of the node in the subnet (for example, 0, 1)

  For example, if you specified a cluster is to have two nodes in a node pool, the two nodes might be named:

  • oke-cywiqripuyg-nsgagklgnst-st2qczvnmba-0
  • oke-cywiqripuyg-nsgagklgnst-st2qczvnmba-1

• Virtual nodes: Names are the same as the node's private IP address. For example, 10.0.5.207.

Do not change the auto-generated names that Kubernetes Engine gives to worker nodes.
