+#### Assigning AWX pods to specific nodes
+
+You can constrain the AWX pods created by the operator to run on a certain subset of nodes. `tower_node_selector` constrains
+the AWX pods to run only on the nodes that match all the specified key/value pairs. `tower_tolerations` allow the AWX
+pods to be scheduled onto nodes with matching taints.

+
+| Name                | Description            | Default |
+| ------------------- | ---------------------- | ------- |
+| tower_node_selector | AWX pods' nodeSelector | ''      |
+| tower_tolerations   | AWX pods' tolerations  | ''      |
+
+Example of customization could be:
+
+```yaml
+---
+spec:
+  ...
+  tower_node_selector: |
+    disktype: ssd
+    kubernetes.io/arch: amd64
+    kubernetes.io/os: linux
+  tower_tolerations: |

+      operator: "Equal"
+      value: "AWX"
+      effect: "NoSchedule"

 #### LDAP Certificate Authority
 
 If the variable `ldap_cacert_secret` is provided, the operator will look for a the data field `ldap-ca.crt` in the specified secret.
