This page will give detailed information on how to setup a docker container for a XWiki server on a linux machine that you have administrative privileges on. This guide will allow you to accomplish such a setup in a straight-forward way.

But first, the following assumptions must be true:

• You have sudo rights on the machine where you're trying to install the XWiki server on
• This machine already has docker fully installed and properly configured on it. Please perform a test installation of any random image from docker hub to ensure that everything works appropriately
• You already own and are in control of a domain name for which you wish to make the XWiki server accessible through. This domain name is already pre-configured to point to the server that you wish to install XWiki on. In my particular case, I already have pentilescu.com configured to point to my VPS and, what I wished to accomplish  was to have a subdomain via which I could access XWiki. In this particular case, this subdomain was wiki.pentilescu.com. To that end, you must have nginx also configured and running on the same server in the background, to have it redirect connections whose destination is a specific port to a subdomain
• Finally, you must have an SMTP email server running somewhere accessible to the docker instance. XWiki will need to use this server to relay account activation emails as well as password reset emails to its users

With all of these details in mind, let's begin!

Configuring an appropriate docker-compose setup

On the machine you wish to run the docker instance on, please go to a directory where you have write access to and make a directory specifically for the docker files that XWiki and its database will write all of their persistent data to. In my particular case, I went to /home/alex/Scripts/xwiki
