+[Alpha] Delete a custom setter for a Resource field
+
+### Synopsis
+
+Delete a custom setter for a Resource field.
+
+  DIR
+
+    A directory containing Resource configuration.
+
+  NAME
+
+    The name of the setter to create.
+
+### Deleting a Custom Setter
+
+**Given the YAML:**
+
+    # resource.yaml
+    apiVersion: v1
+    kind: Service
+    metadata:
+      ...
+    spec:
+      ...
+      ports:
+        ...
+      - name: http
+        port: 8080  # {"type":"integer","x-kustomize":{"partialFieldSetters":[{"name":"http-port","value":"8080"}]}}
+        ...
+
+**Delete setter:**
+
+    # delete a setter for ports
+    $ kustomize cfg set create DIR/ http-port
+
+comment will be removed for this field is not settable any more.
+
+**Newly modified YAML:**
+
+    # resource.yaml
+    apiVersion: v1
+    kind: Service
+    metadata:
+      ...
+    spec:
+      ...
+      ports:
+        ...
+      - name: http
+        port: 8080
+        ...
+
+
+### Deleting a setter used in substitution
+
+If the setter is also used in substitution, it will ask you to delete the substitution first.
+
+
+### Examples
+
+    # delete a setter for port
+    kustomize cfg create-setter DIR/ port
