Associating Pods to the Nodes

This section describes how to associate a pod to the node based on their labels.

After you have configured a cluster, you can associate pods to the nodes through labels. This association enables the pods to get deployed on the appropriate node based on the key-value pair.

Labels are required for the pods to identify the nodes where they must get deployed and to run the services. For example, when you configure the protocol-layer label with the required key-value pair, the pods are deployed on the nodes that match the key-value pair.

  1. To associate pods to the nodes through the labels, use the following configuration:

    configure 
      label 
        cdl-layer   
          key key_value 
          value value 
        oam-layer   
          key key_value 
          value value 
        protocol-layer   
          key key_value 
          value value 
        service-layer   
          key key_value 
          value value 
          end 

NOTES:

  • If you opt not to configure the labels, then SMF assumes the labels with the default key-value pair.

    • label { cdl-layer { key key_value | value value } : Configures the key value pair for CDL.

    • oam-layer { key key_value | value value } : Configures the key value pair for OAM layer.

    • protocol-layer { key key_value | value value } : Configures the key value pair for protocol layer.

    • service-layer { key key_value | value value } : Configures the key value pair for the service layer.
