This article introduces "what Headlamp is" in detail for everyone. The content is detailed, the steps are clear, and the details are handled properly. I hope this article "what Headlamp is" can help you solve your doubts. Let's go deeper and learn new knowledge together with the ideas of Xiaobian.

Cloud-native infrastructure vendor Kinvolk has created a graphical interface that allows Kubernetes users to easily manage Kubernetes without using command-line tools. The project is called Headlamp, which is completely open source and independent of all vendors. Headlamp provides an interactive user interface that can be read and written, rather than just a read-only dashboard.

Headlamp is a universal extensible Kubernetes user interface, the official hope Headlamp as far as possible to support a variety of different users, so whether it is just beginning users, or experienced experts, as well as users with special needs, can use Headlamp to meet the needs, the official mentioned, due to Kubernetes use cases are too diverse, so downstream users usually need to customize UI projects, and Headlamp provides an extension component system to solve this problem, Headlamp backend can load Javascript files, and passed to clients to dynamically load these extensions. The expansion component system provides great flexibility for Headlamp, allowing users to create a variety of new features. For example, users can add buttons to the corresponding pages of Pod by expanding the system to provide Pod operation information. Inspektor, an official tracking widget developed to demonstrate the functionality of the extended component system, allows developers to install Inspektor widgets in clusters. When Traceloop widgets are enabled, the tool will pull all system calls from Pods, so users can view the status of Pods while Pods are still executing, and view system usage records when Pods terminate, for users to simply investigate crash records. Headlamp can change the displayed interface according to the user's permissions. The official mentioned that many Kubernetes read and write the user interface, and cannot integrate the underlying access control well. Therefore, some buttons on the interface provide functions that users do not actually have, such as when the user does not have the permission to modify resources, but the interface has created and deleted buttons, which may cause users to misunderstand. Headlamp checks the Kubernetes RBAC configuration and displays only extensions that can perform operations to provide a better user experience. Officials mentioned that most Kubernetes UI can be divided into two types: managed backend and native desktop application, and each type has advantages and disadvantages. Hosted applications allow users to access the user interface everywhere through a single URL and simply synchronize clustered versions, while desktop applications do not need to host UI applications and have isolation, but the burden of application updates falls on the user. Headlamp provides two ways for users to host UIs in clusters using YAML files, or to install applications on Linux, Mac, and Windows. Headlamp is a separate project from all Kubernetes distributions, Kinvolk says they have their own Kubernetes distribution Lokmotive, and Lokmotive does use Headlamp as its web user interface, but because Headlamp is a separate project, Headlamp supports any certified Kubernetes, not just Lokmotive.
