+##### `nodeSelector`
+`nodeSelector` allows you to run the operator Pod on a node whose labels match the specified nodeSelector labels. You can use this optional feature if you want the operator Pod to run on a Node with particular labels. See [Assign Pods to Nodes](https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#nodeselector) in the Kubernetes documentation for more details. This is not required if the operator Pod can run on any Node.
+
+Example:
+```
+nodeSelector:
+ disktype: ssd
+```
+
+##### `nodeAffinity`
+`nodeAffinity` is conceptually similar to `nodeSelector`, it allows you to constrain the operator Pod to be scheduled on a node with certain labels. Node affinity feature provides advanced capabilities to limit Pod placement on specific nodes. See [Assign Pods to Nodes](https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#node-affinity) in the Kubernetes documentation for more details. This is optional and not required if the operator Pod can run on any Node or when using `nodeSelector`.
+
+Example:
+```
+affinity:
+ nodeAffinity:
+ requiredDuringSchedulingIgnoredDuringExecution:
+ nodeSelectorTerms:
+ - matchExpressions:
+ - key: nodeType
+ operator: In
+ values:
+ - dev
+ - test
+ preferredDuringSchedulingIgnoredDuringExecution:
+ - weight: 1
+ preference:
+ matchExpressions:
+ - key: another-node-label-key
+ operator: In
+ values:
+ - another-node-label-value
+```
+
 ##### `enableClusterRoleBinding`
 Specifies whether the roles necessary for the operator to manage domains
 will be granted using a ClusterRoleBinding rather than using RoleBindings in each managed namespace.
