+## Check runtime configuration
+
+### Use the following ```kubectl get``` commands to generate the ```yaml``` files with the actual deployment status
+
+```
+$ kubectl get deployment mongodb-deployment -o yaml > mongodb-deployment-result.yaml
+
+$ kubectl get deployment mongo-express -o yaml > mongoexpress-deployment-result.yaml
+
+$ kubectl get service mongodb-service -o yaml > mongodb-service-result.yaml
+
+$ kubectl get service mongo-express-service -o yaml > mongoexpress-service-result.yaml
+```
+
+The output files generated with these commands can be found in the current directory.
