Hi all,
I have a running program inside my raspberry and it is running on the field. When I add a new feature to the program or need to fix a bug or change something in the software what I do is going to the near raspberry because I am not able to access its network for some reasons. Instead of doing this I want to publish some software updates of program I wrote without going to the raspberry?
Raspberry has internet access. Idea which came to my mind is, -I dont know if possibble- can Raspberry look into a git repository or some sort of server and if there is change in the version download and run new software?(Again I wont be able to ssh to the raspberry from desk)
Can someone suggest me something?

Git is not a bad idea..
You need to install a script on the pi which "cron" ( or similar service ) will start at regular intervals.
The script does the follwing:
- Do a "git pull",
- look at resultcode or output to see if something new is sucessfully downloaded.
- delete old file, copy in new file.
- kill and restart your program.
A smoother (and less hacky) way is to create a .deb package of your application. And install your application as a systemd service.
- You can add/remove files when needed because all is in the deb-package and old files are automatically removed. ( dont need to manually delete/copy files )
- You can add scripts that automatically restarts the service after installation or the new version. ( dont need to manually restart program )
- You can even have the ( now quite short) upgrade script as part of the package.
-- But you have to learn a thing or two about deb-packages and systemd.

I am totally stranger to the second way. First one looks easier to me. But first I need to do some research. Do you know any good tutorial or documentation about second suggestion?
Also I have a question about second one. Do you have any idea how am i going to change files from a far network? I think again I would need a script which will check for differences between files.
Edit: I found something called capistrano. Would it be my solution?
