You can run directly without docker by downloading it and using the command ./yarr -open

Yarr, a very lightweight RSS reader. https://github.com/nkanaev/yarr

To deploy Yarr within a Docker container, you can use the Docker image provided by Wakeful-Cloud. https://github.com/Wakeful-Cloud/yarr

I have been running it on Raspberry Pi 3 for a couple of months without any issues, so I believe you won’t encounter any problems.
