Запуск Кубков в докере ⇐ Linux

[Anonymous]

After many trial/errors and browsing online I recently was able to run cups in docker. I'm running it on a separate image which is running supervisord, when accessing the container, I can run lpstat and can validate the cups is in fact running. Docker is running locally on my computer, not in a server, and will run like that for the time being.

Now, I'm trying to figure out how to add my printers. I'm using a label printer (`Epson TM-T20III) which is connected via usb to my Mac.

When I attempt to access the cups UI (http://localhost:631/printers/) I'm not accessing the one from docker but the one from my computer.

I tried adding Listen *:631 to my cupsd.conf but when attempting to access http://0.0.0.0:631/ I'm getting a bad request error. It used to be Listen 0.0.0.0:631 but was getting a This site can't be reached.

I tried mapping the port 632 to 631 used in Docker but doesn't work.

Here's my Dockerfile:

Thanks.
