gollum -- A git-based Wiki
DESCRIPTION
Gollum is a simple wiki system built on top of Git. A Gollum Wiki is simply a git repository (either bare or regular) of a specific nature:
- A Gollum repository's contents are human-editable, unless the repository is bare. Pages are unique text files which may be organized into directories any way you choose. Other content can also be included, for example images, PDFs and headers/footers for your pages.
- Gollum pages:
- May be written in a variety of markups.
- Can be edited with your favourite system editor or IDE (changes will be visible after committing) or with the built-in web interface.
- Can be displayed in all versions (commits).
Gollum can be launched either as a webserver (with the web interface) or in "console mode", where you can use a predefined API to query and manipulate the repository. For more information, see the Running and Configuration sections.

SYSTEM REQUIREMENTS
Operating System | Ruby | Adapters | Supported |
---|---|---|---|
Unix/Linux-like | Ruby 1.9.3+ | all except RJGit | yes |
Unix/Linux-like | JRuby (1.9.3+ compatible) | RJGit | yes |
Windows | Ruby 1.9.3+ | all except RJGit | no |
Windows | JRuby (1.9.3+ compatible) | RJGit | almost1 |
Notes:
- There are still some bugs and this setup is not ready for production yet. You can track the progress at Support Windows via JRuby - Meta Issue.
INSTALLATION
Varies depending on operating system, package manager and Ruby installation. Generally, you should first install Ruby and then Gollum.
- Ruby is best installed either via RVM or a package manager of choice.
- Gollum is best installed via RubyGems:
[sudo] gem install gollum
Installation examples for individual systems can be seen here.
Notes:
- Whichever Ruby implementation you're using, Gollum ships with the appropriate default git adapter. So the above installation procedure is common for both MRI and JRuby.
- If you're installing from source:
- Optionally uninstall any previous versions of Gollum:
[sudo] gem uninstall -aIx gollum
- Install Bundler.
- Navigate to the cloned source of Gollum.
- Install dependencies:
[sudo] bundle install
- Build:
rake build
- And install:
[sudo] gem install --no-document pkg/gollum*.gem
- Optionally uninstall any previous versions of Gollum:
Markups
Gollum presently ships with support for the following markups:
Since all markups are rendered by the github-markup gem, you can easily add support for other markups by additional installation:
- AsciiDoc --
[sudo] gem install asciidoctor
- Creole --
[sudo] gem install creole
- MediaWiki --
[sudo] gem install wikicloth
- Org --
[sudo] gem install org-ruby
- Pod -- requires Perl >= 5.10 (the
perl
command must be available on your command line)- Lower versions should install
Pod::Simple
from CPAN.
- Lower versions should install
- ReStructuredText -- requires python >= 2 (the
python2
command must be available on your command line)- Note that Gollum will also need you to install
docutils
for your Python 2. Installation procedure can, again, vary depending on operating system and package manager.
- Note that Gollum will also need you to install
- Textile --
[sudo] gem install RedCloth
By default, Gollum ships with the kramdown
gem to render Markdown. However, you can use any Markdown renderer supported by github-markup. The thing to remember is that the first installed renderer from the list will be used. So, for example, redcarpet
will NOT be used if github/markdown
is installed.
RUNNING
Simply:
- Navigate to your git repository (wiki) via the command line.
- Run:
gollum
. - Open
http://localhost:4567
in your browser.
This will start up a web server (WEBrick) running Gollum with a web interface, where you can view and edit your wiki.
Running from source
git clone https://github.com/gollum/gollum
cd gollum
[sudo] bundle install
(may not always be necessary).bundle exec bin/gollum
- Like that, gollum assumes the target wiki (git repository) is the project repository itself. If it's not, execute
bundle exec bin/gollum <path-to-wiki>
instead.

Rack
Gollum can also be ran with any rack-compatible web server. More on that over here.
Rack, with an authentication server
Gollum can also be ran alongside a CAS (Central Authentication Service) SSO (single sign-on) server. With a bit of tweaking, this adds basic user-support to Gollum. To see an example and an explanation, navigate over here.
Docker
Gollum can also be ran via Docker. More on that over here.
Service
Gollum can also be ran as a service. More on that over here.
CONFIGURATION
Gollum comes with the following command line options:
Option | Arguments | Description |

--base-path | [PATH] | Specify the leading portion of all Gollum URLs (path info). Setting this to /wiki will make the wiki accessible under http://localhost:4567/wiki/ . Default: / . |
--page-file-dir | [PATH] | Specify the subdirectory for all pages. If set, Gollum will only serve pages from this directory and its subdirectories. Default: repository root. |
--css | none | Tell Gollum to inject custom CSS into each page. Uses custom.css from repository root.3,5 |

--no-live-preview | none | Disable the live preview feature in page editor. |

Notes:
- The
0.0.0.0
IP address allows remote access. Should you wish for Gollum to turn into a personal Wiki, use127.0.0.1
. - Before using
--adapter
, you should probably read this first. - When
--css
or--js
is used, respective files must be committed to your git repository or you will get a 302 redirect to the create a page. - Files can be uploaded simply by dragging and dropping them onto the editor's text area (this is, however exclusive to the default editor, not the live preview editor).
- Read the relevant Security note before using these.
Config file
When --config
option is used, certain inner parts of Gollum can be customized. This is used throughout our wiki for certain user-level alterations, among which customizing supported markups will probably stand out.
All of the mentioned alterations work both for Gollum's config file (config.rb
) and Rack's config file (config.ru
).
