A git-based wiki with auth and registration

Realms

Realms is a git-based wiki (like Gollum, but with basic authentication and registration)

Features include:

• Built with Bootstrap 3.
• Markdown (w/ HTML Support).
• Syntax highlighting (Ace Editor).
• Live preview.
• Collaboration (TogetherJS / Firepad).
• Drafts saved to local storage.
• Handlebars for templates and logic.

!!! warning "Project likely abandoned"

In my limited trial, Realms seems _less_ useful than [Gollum](/recipes/gollum/) for my particular use-case (_i.e., you're limited to markdown syntax only_), but other users may enjoy the basic user authentication and registration features, which Gollum lacks.

Also of note is that the docker image is 1.17GB in size, and the handful of commits to the [source GitHub repo](https://github.com/scragg0x/realms-wiki/commits/master)  in the past year has listed TravisCI build failures. This has many of the hallmarks of an abandoned project, to my mind.

Preparation

Setup data locations

Since we'll start with a basic Realms install, let's just create a single directory to hold the realms (SQLite) data:

mkdir /var/data/realms/

Create realms.env, and populate with the following variables (if you intend to use an oauth_proxy to double-secure your installation, which I recommend)

OAUTH2_PROXY_CLIENT_ID=
OAUTH2_PROXY_CLIENT_SECRET=
OAUTH2_PROXY_COOKIE_SECRET=

Setup Docker Swarm

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

--8<-- "premix-cta.md"

version: "3"

services:
  realms:
    image: realms/realms-wiki:latest
    env_file: /var/data/config/realms/realms.env
    volumes:
      - /var/data/realms:/home/wiki/data
    networks:
      - internal

  realms_proxy:
    image: funkypenguin/oauth2_proxy:latest
    env_file : /var/data/config/realms/realms.env
    networks:
      - internal
      - traefik_public
    deploy:
      labels:
        - traefik.frontend.rule=Host:realms.funkypenguin.co.nz
        - traefik.docker.network=traefik_public
        - traefik.port=4180
    volumes:
      - /var/data/config/realms/authenticated-emails.txt:/authenticated-emails.txt
    command: |
      -cookie-secure=false
      -upstream=http://realms:5000

      -http-address=http://0.0.0.0:4180
      -email-domain=funkypenguin.co.nz
      -provider=github
      -authenticated-emails-file=/authenticated-emails.txt

  traefik_public:

    ipam:
      config:
        - subnet: 172.16.35.0/24

Serving

Launch Realms stack

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

Log into your new instance at https://YOUR-FQDN, authenticate against oauth_proxy, and you're immediately presented with Realms wiki, waiting for a fresh edit ;)
