Just found it and tried on my home server, it works:

version: '3.3'
services:
  yarr:
    container_name: yarr
    image: maskalicz/yarr:latest
    ports:
    - 7070:7070
    volumes:
    - ./yarr-data:/data:rw

Anyway, it just have one view mode with 3 panels and it’s not customizable. At the moment, the most featured and exstesible RSS Feed service seems to be FreshRSS as suggested in the thread by @specseaweed@lemmy.world.
