Chapter 19. Configuring node agents and node labels

Procedure

1. Run the node agent on any node that you choose by adding a custom label:

   $ oc label node/<node_name> node-role.kubernetes.io/nodeAgent=""

   Note

   Any label specified must match the labels on each node.

2. Use the same custom label in the DPA.spec.configuration.nodeAgent.podConfig.nodeSelector field, which you used for labeling nodes:

   configuration:
     nodeAgent:
       enable: true
       podConfig:
         nodeSelector:
           node-role.kubernetes.io/nodeAgent: ""

   The following example is an anti-pattern of nodeSelector and does not work unless both labels, node-role.kubernetes.io/infra: "" and node-role.kubernetes.io/worker: "", are on the node:

       configuration:
         nodeAgent:
           enable: true
           podConfig:
             nodeSelector:
               node-role.kubernetes.io/infra: ""
               node-role.kubernetes.io/worker: ""
