HA on NUC with Docker not visible to local network

I managed to install HA on my Ubuntu NUC as a Docker installation following this guide: https://medium.com/@jordanrounds/intel-nuc-home-assistant-supervised-7cc52d81744a

The HA ui works like a charm on that machine using its local IP 192.168.1.2:8123 . However, when I try to access it from other computers on my local network, nothing is found.

Any suggestions?

Set networking of the Container to host mode or add the port mappings. Do you use docker compose?

I’m a 100% newbie on this. I have Portainer to manage the containers.

According to the medium link, it is some kind of nonstandard supervised install.
