BookStack

BookStack is a simple, self-hosted, easy-to-use platform for organising and storing information.

A friendly middle ground between heavyweights like MediaWiki or Confluence and Gollum, BookStack relies on a database backend (so searching and versioning is easy), but limits itself to a pre-defined, 3-tier structure (book, chapter, page). The result is a lightweight, approachable personal documentation stack, which includes search and Markdown editing.

I like to protect my public-facing web UIs with an oauth_proxy, ensuring that if an application bug (or a user misconfiguration) exposes the app to unplanned public scrutiny, I have a second layer of defense.

Preparation

Setup data locations

We'll need several directories to bind-mount into our container, so create them in /var/data/bookstack:

mkdir -p /var/data/bookstack/database-dump
mkdir -p /var/data/runtime/bookstack/db

Prepare environment

Create bookstack.env, and populate with the following variables. Set the oauth_proxy variables provided by your OAuth provider (if applicable.)

# For oauth-proxy (optional)
OAUTH2_PROXY_CLIENT_ID=
OAUTH2_PROXY_CLIENT_SECRET=
OAUTH2_PROXY_COOKIE_SECRET=

# For MariaDB/MySQL database
MYSQL_RANDOM_ROOT_PASSWORD=true
MYSQL_DATABASE=bookstack
MYSQL_USER=bookstack
MYSQL_PASSWORD=secret

# Bookstack-specific variables
DB_HOST=bookstack_db:3306
DB_DATABASE=bookstack
DB_USERNAME=bookstack
DB_PASSWORD=secret

Setup Docker Swarm

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

version: '3'

Serving

Launch Bookstack stack

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

Log into your new instance at https://YOUR-FQDN, authenticate with oauth_proxy, and then login with username 'admin@admin.com' and password 'password'.
