Extending Nomad with Plugins
summary
Nomad adds two plugin types: a Python task driver (a separate binary using the HashiCorp go-plugin library) that starts, recovers and reports a task handle, and a USB device plugin that fingerprints devices, reserves them and provides mounts/envs — the demo runs on a single-node laptop, the Python job is placed and served, and plugging in a 13‑year‑old Memorex flash drive makes the pending device job schedule. Nomad 0.9 adds plugins; core claim: plugins are small, mostly boilerplate. 1 million containers scheduling test finishes in minutes.
