Hello, My team has been attempting to use StarlingX (R5, Distributed cloud deployment) to monitor and maintain edge cloud servers. Part of our desired workload is a K8s deployment from one of the subcloud controllers. Ideally, some pods of this workload would run on lightweight node such as a Raspberry Pi (running only K8s, not StarlingX software) but we are having trouble joining this device to the subcloud's existing K8s cluster. There seem to have been features in StarlingX related to this in previous releases but perhaps they have been deprecated. I've attached screenshots / links below. Any assistance joining outside nodes to the K8s cluster would be appreciated.
