+## Running on Kubernetes
+
+To Run the demo on kubernetes cluseter locally like minikube or docker
+kubernetes, we can apply the config present in `k8s_local` directory.
+Please be aware that this will deploy the application to the context.
+`kubectl` is set to.
+
+```shell
+make k8s_local_apply
+```
+
+We can port-forward to view ui, prometheus , jaeger & grafana .
+We can do port-forward to the services using the script.
+
+```shell
+k8s_local/port_forward.sh
+```
+
+Once the port-forward is successful we can view
+
+- Webstore: <http://localhost:8080/>
+
+- Jaeger: <http://localhost:16686/>
+
+- Prometheus: <http://localhost:9090/>
+
+- Grafana: <http://localhost:3000/>
+
+To clean up the setup from kubernetes cluster run the command.
+Please make sure you are using right kubernetes context.
+The command will fail at first error
+
+```shell
+make k8s_local_clean
+```
