1 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.
2
3 But first, the following assumptions must be true:
4
5 * You have sudo rights on the machine where you're trying to install the XWiki server on
6 * 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
7 * 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
8 * 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

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

16
17 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/" and created an empty "xwiki" directory in it. The exact location of this directory is not particularly important but, if you do regular backups of your machine and you wish for all the XWiki data to also be backed up by these processes, keep in mind to create this folder in a location that's being backed up by your preferred solution, as this directory will contain all the database and XWiki pages that you will be creating, including all attachments uploaded by your users.
18
19 Afterwards, in this newly created directory, please create the following empty subdirectory: mariadb
20 This subdirectory will contain the contents of two configuration files that will later be mapped by docker into the XWiki containers. After creating the "mariadb" directory, cd into it and then run the following bash command in it:
21
22 {{code language="bash"}}
23 wget https://raw.githubusercontent.com/xwiki-contrib/docker-xwiki/master/14/mariadb-tomcat/mariadb/init.sql
24 wget https://raw.githubusercontent.com/xwiki-contrib/docker-xwiki/master/14/mariadb-tomcat/mariadb/xwiki.cnf
25 {{/code}}

28
29 Finally, once both of those files are downloaded, please proceed to cd back into the parent directory (which is "xwiki" in my case) and then create a docker-compose.yml file with the following contents:

114 There are many different configurations you can use to have an XWiki server. For one, mariadb is NOT required to install XWiki, it's simply one of many database solutions that XWiki is compatible with. Alternatively, you may use MySQL or even PostgreSQL, instead. To see docker-compose configuration options for those, please reference the full official docker reference guide for XWiki at the "External references" section of this page for more details. **Keep in mind, though, in case you do decide to use an alternative to mariadb, to download a different init.sql file than the one mentioned in the previous step!**
115
116 Finally, in the current directory that you are in, please create another subdirectory called "data" containing the empty subdirectories "mariadb-data" and "xwiki-data". The mariadb-data directory will contain all the persistent data from the database and the xwiki-data will contain the persistent data with respect to our XWiki installation, such as XWiki extensions, icons, as well as user-uploaded attachments.
117
118 One last note: the subnet 192.168.80.x IP address space configured for our docker network may be changed to whatever suits your particular needs, although, if you do use a different IP space, please keep in mind to also change the reference "mynetworks" configuration for postfix accordingly, as explained in the "Configuring Postfix to send XWiki emails" section of this page.
119
120 Now, all we need to do is create a ".env" file in the main directory ("xwiki" is the name of my directory) containing the following contents:
121
122 {{code language="ini"}}
123 DB_USER=xwiki
124 DB_PASSWORD=<database_password>
125 MYSQL_ROOT_PASSWORD=<mysql_root_password>
126 DB_DATABASE=xwiki
127 XWIKI_VERSION=1.0
