Small update : although fearful of breaking my production Cloudron, I installed the Netbird client on the box (via command line outside the Cloudron environment - sorry Cloudron team).
Did netbird up -m <separate VPS running management server> -k <netbird key>.
Worked flawlessly.
On management server, added my Cooudron netbird peer into my private network.
Now apps on Cloudron can reach my laptop, and vice versa, via private network.
Specifically a Cloudron app can use Ollama on my laptop running a private model to benefit from Mac Silicon "nearly-gpu-like" performance.
My Cloudron Ollama can't properly run the model because it is CPU only.
Cloudron Ollama running local model on CPU runs at ~6 tokens, or lower.
Mac Ollama private local model achieves ~40 tokens/second.
Not as good as on-demand GPU instance at 80-150 t/s or running an ollama:cloud model also at 80-150 t/s (model dependent).
But 40 t/s is not too shabby and and is viable performance without the cost of an always-on or on-demand GPU.
So getting Netbird management server on Cloudron would definitely be a good thing. Shall try to pick that up shortly.
