Have you ever used portainer…a webgui for working with docker images
Might be able to pull up the docker and see if it has a different port aimed at 8123
nice thing is, it allows you to make changes and rebuild the docker image on the fly with minimal issues

#Run this command to install Portainer 2.0
docker run -d -p 9000:9000 -p 8000:8000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce
Digging around also found other howto’s

This one from dockerhub has over 100 million downloads
https://hub.docker.com/r/homeassistant/home-assistant
here is the howto I finally found from the page above

I can confirm I just installed the docker image on my test Orange Pi PC and it built the container…it DID however take 30-45 min to uncompress all the downloaded images it needed to run!!! (my OPiPC has a heatsink, active cooling, and cpufrequtils set to performance)
I used this command and it worked flawlessly
docker run --init -d --name="home-assistant" -e "TZ=America/Chicago" -v /home/warhawk/homeassistant:/config --net=host homeassistant/raspberrypi3-homeassistant:stable
Change your -v directory to one on your machine…
