Chapter 25. Configuring Velero load affinity


With each OADP deployment, there is one Velero pod and its main purpose is to schedule Velero workloads. To schedule the Velero pod, you can use the velero.podConfig.nodeSelector and the velero.loadAffinity objects in the DataProtectionApplication (DPA) custom resource (CR) spec.

Use the podConfig.nodeSelector object to assign the Velero pod to specific nodes. You can also configure the velero.loadAffinity object for pod-level affinity and anti-affinity.

The OpenShift scheduler applies the rules and performs the scheduling of the Velero pod deployment.

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 velero.podConfig.nodeSelector and the velero.loadAffinity objects in the DPA spec as shown in the following examples:

    • velero.podConfig.nodeSelector object configuration:

      ...
      spec:
        configuration:
          velero:
            podConfig:
              nodeSelector:
                some-label.io/custom-node-role: backup-core

        configuration:
          velero:
            loadAffinity:
              - nodeSelector:
                  matchLabels:
                    label.io/gpu: 'no'
                  matchExpressions:
                    - key: label.io/location
                      operator: In
                      values:
                        - US
                        - EU
