Headlamp: User-added Cluster Support in Shared Headlamp Deployments
Headlamp supports running as both a desktop application and as a web service in-cluster. Each environment has its own set of characteristics and limitations. One characteristic of the in-cluster deployment is that it can provide shared access. This shared access poses issues with security and privacy. For this reason, we enabled the ability to add/remove clusters only for the desktop version of Headlamp, as it is, by definition, a single user instance. This meant, for example, that users were not able to add or modify which clusters would show, when using Headlamp as a web service. This is a limitation that we wanted to overcome to support a variety of very valid use cases.
