Unknown container during restart?

I’ve installed hass.io using these instructions: “https://github.com/home-assistant/hassio-build/tree/master/install#install-hassio”. Works fine so far on a mini-PC!

What I’ve noticed is that if i restart HA from within the webgui, i see a container spun up (I use docker stats) with random names (last time it was laughing_mahavira and seems to be always 2 words with an underscore in between). Does anyone know what this is? Is this to be expected or is my installation flawed?

I’ve only installed the hass.io node-red plugin so far b.t.w.

thanks in advance!

That’s how docker names containers.

Good to know. Thnkx!
