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 Screenshot

As you'll note in the (real world) screenshot above, my requirements for a personal wiki are:

  • Portable across my devices
  • Supports images
  • Full-text search
  • Supports inter-note links
  • Revision control

Gollum meets all these requirements, and as an added bonus, is extremely fast and lightweight.


Since Gollum itself offers no user authentication, this design secures gollum behind traefik-forward-auth, so that in order to gain access to the Gollum UI at all, authentication must have already occurred.

Gollum Requirements


Already deployed:



Setup data locations

We'll need an empty git repository in /var/data/gollum for our data:

mkdir /var/data/gollum
cd /var/data/gollum
git init

Gollum Docker Swarm config

Create a docker swarm config file in docker-compose syntax (v3), something like the example below:

Fast-track with premix! 🚀

I automatically and instantly share (with my sponsors) a private "premix" git repository, which includes necessary docker-compose and env files for all published recipes. This means that sponsors can launch any recipe with just a git pull and a docker stack deploy 👍.

🚀 Update: Premix now includes an ansible playbook, so that sponsors can deploy an entire stack + recipes, with a single ansible command! (more here)

Setup unique static subnets for every stack you deploy. This avoids IP/gateway conflicts which can otherwise occur when you're creating/removing stacks a lot. See my list here.


Launch Gollum stack

Launch the Gollum stack by running docker stack deploy gollum -c <path-to-docker-compose.yml>

Chef's notes 📓

  1. In the current implementation, Gollum is a "single user" tool only. The contents of the wiki are saved as markdown files under /var/data/gollum, and all the git commits are currently "Anonymous"
