I have a GitHub project in which I store data collected by bicycle counting stations scattered around Cologne, Germany. At the moment, I update the data manually by running a Python script, which fetches the data and appends it to CSV-files. I then add and push the changes using git to the GitHub Project.

I would like to automate this process using an existing Elixir + Phoenix application I have running on Heroku. Since that app doesn’t do much, I thought that I could add a reoccurring job, maybe using Oban, which would fetch and push the data on a daily basis. The problem that I am facing now is how to implement this “in a smart way”.

My current plan is to clone the git repository to my Heroku machine and perform the git actions using e.g. elixir-git-cli. However, this feels a bit clunky and I was wondering whether you have an idea or experiences with automating reoccurring jobs which use git commands? Is there maybe a way to push changes to GitHub without having to clone a git repository first?
