The main dokuwiki page dokuwiki_setup.

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

Todo:

• 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.

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.
