Plugins are one of the key features of Headlamp. They allow you to change how and what information is displayed, as well as other functionality. The ultimate goal of the plugins system is to allow vendors to build and deploy Headlamp with extra functionality without having to maintain a fork of the project.
Plugins are supposed to be built and shipped out-of-tree, i.e. instead of managing the plugins’ code within the Headlamp project or a Headlamp fork (which would require always rebuilding/maintaining Headlamp when changing a plugin), they’re supposed to be built outside of the project and just pointed to by the Headlamp’s server.
⚠️ IMPORTANT FOR DEVS: The plugins system and plugins lib is still in the process of being consolidated. This means that 1) it’s subject to change, 2) you are very welcome to contribute to it with different use cases and/or development.
