Running a python app directly on the server

OS
1

Hi!
I would like to run a small python app directly on the server. However, python is not installed on the system, which kind of came as a surprise to me. So, two questions, I guess:

  1. Would it harm to “just” install it? The overall list of installed packages is pretty large, so I fear that it might break something …

But then again, python is a pretty standard package, so it should be unproblematic, shouldn’t it?

  1. Is there a better way to directly run a python app? Maybe in a docker container, but docker isn’t installed, either. :slight_smile: The list of dependencies is much shorter, though – would that be safer?

What are your thoughts on this? :light_bulb:

Cheers

Hi,

There is no OS python as Syncloud apps are not using almost any OS packages for stability. Installing python using apt should be safe thought.
By the way docker package in buster is not the docker you are looking for :slight_smile: Debian -- Details of package docker in buster

Also make sure you have backups then in case you break something restoring the system should not be hard either.

Oh haha, good to know! :smile:

Thanks for the info, I’ll try it out. :+1:
