The main dokuwiki page dokuwiki_setup.

This uses the linuxserver.io image from dockerhub, linuxserver/dokuwiki. The Linuxserver.io documents can be found heredoc.linuxserver.io.

Defines web_data volume:

#Not USED

• Need to create a local LAN only functional back-up of the wiki in my back-up server so I have a backup in case the main wiki with my configuration notes becomes unavailable.

This wiki is used to help setup and maintain my home server, so if the server becomes unavailable

Some of the following nuances may help when transferring Dokuwiki servers:

• The dokuwiki image uses the following permanent volume storage, in config/dokuwiki:
  • conf (basically copy everything from existing to here)
  • data (basically copy everything from existing to here)
  • inc → /app/www/public/inc (symlink back to container, no point changing)
  • lib (basically copy everything from existing to here)
  • vendor → /app/www/public/vendor (symlink back to container, no point changing)

The DokuWiki page How to backup DokuWiki? has the basic information to backup a Dokuwiki.

After setting up the internal indexes could be messed up. The plugin SearchIndex Manager can be used to recreate these indexes.

php /php-fpm overrides are in the config/php directory. The files in this directory can be used to set php.ini and www.conf override settings. I followed the direction for php settings from dokuwiki. I use my preferred settings for php-fpm. (I appreciate that dokuwiki does not need a lot of resources, however I do not want performance to be resource limited. Many of the setting are maximum allowances, an do not use resources unless needed.)

I noticed a few days after implementing these changes the Wiki response had improved. The page updates seemed much faster.

Dokuwiki defaults to opening all links in the same page. I prefer external links the be opened in a new tab. The option can be set under admin/configuration/Link Settings/extern. Set to _tab for external links to open in new tab. See Configuring DokuWiki and Configuration Setting: target.
