+= Patching Ingress objects to resolve an ingressWithoutClassName alert
+
+The `ingressClassName` field specifies the name of the `IngressClass` object. You must define the `ingressClassName` field for each `Ingress` object.
+
+If you have not defined the `ingressClassName` field for an `Ingress` object, you could experience routing issues. After 24 hours, you will receive an `ingressWithoutClassName` alert to remind you to set the `ingressClassName` field.
+
+.Procedure
+
+Patch the `Ingress` objects with a completed `ingressClassName` field to ensure proper routing and functionality.
+
+. List all `IngressClass` objects:
++
+[source,terminal]
+----
+$ oc get ingressclass
+----
+
+. List all `Ingress` objects in all namespaces:
++
+[source,terminal]
+----
+$ oc get ingress -A
+----
+
+. Patch the `Ingress` object:
++
+[source,terminal]
+----
+$ oc patch ingress/<ingress_name> --type=merge --patch '{"spec":{"ingressClassName":"openshift-default"}}'
+----
++ 
+Replace `<ingress_name>` with the name of the `Ingress` object. This command patches the `Ingress` object to include the desired ingress class name.
