Chapter 20. Configuring node agent load affinity

Prerequisites

• You must be logged in as a user with cluster-admin privileges.
• You have installed the OADP Operator.
• You have configured the DPA CR.

Procedure

• Configure the DPA spec nodegent.loadAffinity object as shown in the following example.

  In the example, you ensure that the node agent pods are scheduled only on nodes with the label label.io/role: cpu-1 and the label label.io/hostname matching with either node1 or node2.

  ...
  spec:
    configuration:
      nodeAgent:
        enable: true
        loadAffinity:
          - nodeSelector:
              matchLabels:
                label.io/role: cpu-1
              matchExpressions:
                - key: label.io/hostname
                  operator: In
                  values:
                    - node1
                    - node2
                    ...
