I made a docker image for this: https://github.com/agonzalezro/docker-hnwatch
If you want to run it: docker run -it agonzalezro/hnwatch
I don't know why but hnwatch doesn't look like working ATM. I've tried in a Linux box (without docker) and I have the same problem with the tty, it's just loading 4 news and no comments or similar.
