TKL MediaWiki

The MediaWiki image provides a so-called wiki engine that is written with the use of the PHP programming language, originally created for the purposes of the Wikipedia. This image allows for making use of all the features of a knowledge base, from its administration, up to creating of knowledge pages, posts and articles and communication with the users of the knowledge base, etc.

After the machine with the given image is started, we can use the web browser to find (at the machine’s IP address) the page very much alike to the Wikipedia’s look. It is possible to log in with the use of the link located in the upper right section of the page. The procedures of editing and managing the content of the knowledge base are far beyond the scope of this manual.

There are the shellinabox, webmin and adminer administration tools available inside the given image. You can find further information regarding these tools in the description of the TKL core image or in the particular separate manuals.
