+# Replacing Octant
+
+[Octant](https://octant.dev) is the tool used in the book to provision a Kubernetes management console in your local environment.
+Since the book got published, Octant stopped being maintained.
+
+This guide describes two alternatives.
+
+## Replacing Octant with HeadLamp
+
+[HeadLamp] is an open-source and CNCF Sandbox project providing a convenient Kubernetes web UI. On your local environment, you can run it as a desktop application.
+
+On macOS and Linux, you can install HeadLamp as follows.
+
+```shell
+brew install --cask headlamp
+```
+
+You can then open HeadLamp as any other desktop application on your machine.
+
+Refer to the [official documentation](https://headlamp.dev/docs/latest/installation/) for more information.
+
+## Replacing Octant with Kubernetes Dashboard
+
+The Kubernetes project provides an optional dashboard that can be installed in a cluster. If you're using minikube like explained in the book, you can provision the dashboard via the official addon.
+
+If you have already a cluster provisioned with minikube, you can access the dashboard UI with the following command.
+
+```shell
+minikube dashboard
+```
+
+Refer to the [official documentation](https://minikube.sigs.k8s.io/docs/handbook/dashboard/) for more information.
