Can I host a single jsonl file that my project writes to via python?

I have a python project being hosted on railway, I would love to be able to, from python, write to the jsonl file from python and for that file to persist accross builds.

Is that possible or do I need to spin up a whole MongoDB server just for 1 files?

Thanks, I just set one up!
Is this the intended use, because this and similar variations didn't seem to work:
``` mountpath = os.getenv("RAILWAYVOLUMEMOUNTPATH")

        data_folder = os.path.join(mount_path, "data")
        os.makedirs(data_folder, exist_ok=True)

        file_path = os.path.join(data_folder, "data_signedin.jsonl")

        new_data = {
          #...data...
        }
        print(new_data)

        with open(file_path, "a") as file:
            file.write(json.dumps(new_data) + "\n")```
