Headlamp: A multicluster management UI for Kubernetes

Other options quickly expose service YAML, using a built-in editor so you can make changes to your environment on the fly. There’s even a terminal so you can interact with a local shell inside your containers.

The more tools in your cluster, the more detail Headlamp exposes. If you’ve got Prometheus installed, it’ll show metrics, using its built-in plug-in. That’s one of the advantages of Headlamp: It’s built around an extensible architecture, which its community can use to add new features to work with the ever-growing Kubernetes environment. If a feature you need isn’t part of the default installation, simply search the Headlamp app catalog and install it with a couple of clicks.

Exploring application deployments

Perhaps the most useful feature is Headlamp’s application map. Starting with a view of the currently managed namespaces, you can drill into individual pods and deployments. Once you start viewing a deployment, you can see how it’s built up of ReplicaSets, pods, services, and endpoints. As you click into the map, you’re presented with more and more detail about how your application is put together and how it’s built on top of a selection of containers. You can use the tools here to forward ports so you can evaluate code, as well as explore how tools like Helm deploy code into your cluster.
