It would be nice to have FitTrackee docker based images 
It’s an Open Source Strava alternative with beautiful web based UI/UX
What is it you are missing form the docker image they are offering?
regards
It’s for development that means you’ve have to build docker image manually.
As it’s described in the documentation :
https://samr1.github.io/FitTrackee/en/installation.html#id6
It might be good to have a FitTrackee docker image build automatically like another LinuxServer image for example Docker (variables are included in the docker-compose.yml). docker compose pull && docker compose up -d (and the container starts )
I agree the Docker upgrade process is rather tedious if it works at all, I have tried to deploy Docker Image, but having no experience I have failed miserably.
