Hi,
Disclaimer: I do this to advertise to new owners of a Raspberry Pi 4 who struggled to make TTRSS work. Since fox doesn’t provide an image for Raspberry Pi 4, I made one for myself and thought to share. 
I have spent some time time trying to make TTRSS work on my Raspberry Pi 4 (armv7), and I learned about a wonderful feature of GitHub: GitHub Actions.
Basically, they automate actions. I have set one up to build TTRSS for Raspberry Pi 4 and push the image to DockerHub.
I can’t promise that it won’t break, especially if there are changes in the docker compose repository, but it’s an easy way to rely on an image already built, and anyone can copy what I did to have their own image themselves.
More specifically, I sync the docker compose repo to my repo’s TTRSS-docker branch (have to create it before running this Action), then build it, and push it to DockerHub (have to create the repo before). I do this for the app (schklom/ttrss-app) and web-nginx (schklom/ttrss-web-nginx) containers.
My repo is private, but I share the code below.
You can use
image: schklom/ttrss-app
instead of
build:
context:
./app
for the app, backups, and updater containers.
AFAIK, the updater updates every day, so I update my image every day as well.
For info, here is the action defined in my private repo (myrepo/.github/workflows/TTRSS.yml).
I have set up repository secrets obviously.
