Just thought I'd share in case anyone else lands here like I did.
I'm traveling for work and not at home, so there was only so much I could do, but based on my limited success, I can shed some light on getting the docker container config set up on unRAID along with the sh command that seems to be a point of confusion in this thread.
Thanks to the video posted by @DZMM, I was able to figure this out fairly easily.
I had also initially created the setup.sh script in the /config folder using notepad++, as this is how I frequently do it for Home Assistant, but there were formatting and permission issues (the latter was warned in the video) so I just recreated the file using vi from the container's terminal and presto.
ADB isn't enabled on my TV at home, which is the limitation I mentioned earlier so I get the "No route to host" error, but I'm fairly confident this will work when I get it enabled.
Good luck!
