+#### [WeaveScope](https://github.com/weaveworks/scope) **(E.O.L)**
+
+Weave also provides a powerful visualization and monitoring tool specifically designed for Docker and Kubernetes environments called scope.
+
+```bash
+### Install
+> kubectl apply -f https://github.com/weaveworks/scope/releases/download/v1.13.2/k8s-scope.yaml
+### Uninstall
+> kubectl delete -f https://github.com/weaveworks/scope/releases/download/v1.13.2/k8s-scope.yaml
+```
+
+By default, weavescope uses Cluster IP address, so we need to `port-forward` it to the node IP address and port.
+
+```bash
+> kubectl port-forward svc/weave-scope-app -n weave 4040:80 --address YOUR_NODE_IP
+```
+
+and then, you should see the following UI via `http://<YOUR_NODE_IP>:4040/`
