.. _requirements: =================== Server Requirements =================== Operating System ================ We require using Ubuntu 18.04 as the base operating system for your server. 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. CPU / Memory / Disk Space ========================= See how to :ref:`howto/admin/resource-estimation`
