Ingredients

Docker swarm cluster with persistent shared storage
Traefik configured per design

Preparation

Setup data locations

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

mkdir /var/data/wekan
cd /var/data/wekan
mkdir -p {wekan-db,wekan-db-dump}

Prepare environment

Create wekan.env, and populate with the following variables

OAUTH2_PROXY_CLIENT_ID=
OAUTH2_PROXY_CLIENT_SECRET=
OAUTH2_PROXY_COOKIE_SECRET=
MONGO_URL=mongodb://wekandb:27017/wekan
ROOT_URL=https://wekan.example.com
MAIL_URL=smtp://wekan@wekan.example.com:password@mail.example.com:587/
MAIL_FROM="Wekan <wekan@wekan.example.com>"

Setup Docker Swarm

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

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

version: '3'

services:

  wekandb:
    image: mongo:3.2.15
    command: mongod --smallfiles --oplogSize 128
    networks:
      - internal
    volumes:
      - /var/data/wekan/wekan-db:/data/db
      - /var/data/wekan/wekan-db-dump:/dump

  proxy:
    image: zappi/oauth2_proxy
    env_file: /var/data/wekan/wekan.env
    networks:
      - traefik
      - internal
    deploy:
      labels:
        - traefik.frontend.rule=Host:wekan.example.com
        - traefik.docker.network=traefik
        - traefik.port=4180
    command: |
      -cookie-secure=false

      -redirect-url=https://wekan.example.com
      -http-address=http://0.0.0.0:4180
      -email-domain=example.com
      -provider=github

  wekan:
    image: wekanteam/wekan:latest
    networks:
      - internal
    env_file: /var/data/wekan/wekan.env

networks:
  traefik:
    external: true
  internal:
    driver: overlay
    ipam:
      config:
        - subnet: 172.16.3.0/24

!!! note 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.

Serving

Launch Wekan stack

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

Log into your new instance at https://YOUR-FQDN, with user "root" and the password you specified in gitlab.env.

Chef's Notes

If you wanted to expose the Wekan UI directly, you could remove the oauth2_proxy from the design, and move the traefik-related labels directly to the wekan container. You'd also need to add the traefik network to the wekan container.
