Server Requirements
|
|
===================
|
|
|
|
Operating System
|
|
================
|
|
|
|
We recommend using Ubuntu 18.04 as the base operating system for your server.
|
|
Ubuntu 16.04 should also work, but is not officially supported. other Linux
|
|
distributions and operating systems are also not officially supported.
|
|
|
|
Root access
|
|
===========
|
|
|
|
Full ``root`` access to this server is required. This might be via ``sudo``
|
|
(recommended) or by direct access to ``root`` (not recommended!)
|
|
|
|
External IP
|
|
===========
|
|
|
|
An external IP allows users on the internet to reach your JupyterHub. Most
|
|
VPS / Cloud providers give you a public IP address along with your server. If
|
|
you are hosting on a physical machine somewhere, talk to your system administrators
|
|
about how to get HTTP traffic from the world into your server.
|
|
|
|
Memory (RAM)
|
|
============
|
|
|
|
RAM is often the biggest limiting factor to the question 'how many users can use this JupyterHub
|
|
at the same time?'. If you want to support ``N`` maximum concurrent active users
|
|
each able to use up to ``X`` GB of RAM, you will need:
|
|
|
|
.. math::
|
|
|
|
Server RAM = ($N \times X) + 128MB
|
|
|
|
The 128MB buffer is for system services (including JupyterHub itself).
|
|
This will guarantee that your server will not run out of RAM as long
|
|
as you have no more than ``N`` active users.
