Installing dokuwiki using Docker and Ubuntu

July 2, 2023

Why?

We need to organize our docs and information about the gcn and bolha collective and dokuwiki is the best wiki because we don't need a database, it's a flatfile system.

Fast, flexible and easy to backup.

What do I need to install?

You need a Linux Server with Docker, and Docker-compose installed.

What's my setup?

ProxMox
- KVM
- Ubuntu 20.04
  - Docker
  - Docker-compose
External Nginx
- Reverse Proxy Configuration
- LetsEncrypt Certificate

Where I can find more about the project?

How I can install it?

first, let's create the directories

mkdir -p /opt/dokuwiki/docker
mkdir -p /opt/dokuwiki/data

then, let's create the docker-compose file

cd /opt/dokuwiki/docker
vim docker-compose.yaml

here follows the content, change the parameters for you setup

version: '3'
services:
  dokuwiki:
    image: lscr.io/linuxserver/dokuwiki:latest
    container_name: dokuwiki
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
    volumes:
      - dokuwiki_config:/config
    ports:
      - 8081:80
    restart: unless-stopped

volumes:
  dokuwiki_config:
    driver_opts:
      type: none
      device: /opt/dokuwiki/data
      o: bind

all right, let's spin up the dokuwiki

docker-compose up -d

No finish the configuration using the web browser

https://dokuwiki.domain.tld/install.php

external nginx

In our case, Dokuwiki is behind an External NGINX Reverse Proxy.

Here follow the config snippet used

upstream dokuwiki {
    server your_docker_host_ip:your_dokuwiki_port fail_timeout=0;
}

server {
  listen 144.217.95.91:80;
  server_name dokuwiki.domain.tld;
  return 301 https://dokuwkrequest_uri;
}

server {

  listen 144.217.95.91:443 ssl http2;
  server_name dokuwiki.domain.tld;

  access_log /var/log/nginx/dokuwiki-domain-tld.log;
  error_log /var/log/nginx/dokuwiki-domain-tld.log;

  ssl_certificate /etc/letsencrypt/live/domain.tld/fullchain.pem;
  ssl_certificate_key /etc/letsencrypt/live/domain.tld/privkey.pem;

  ssl_protocols TLSv1.2 TLSv1.3;
  ssl_prefer_server_ciphers on;
  ssl_dhparam /etc/letsencrypt/dh-param.pem;

  ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256';

  ssl_session_cache shared:SSL:10m;
  ssl_session_tickets off;

  location / {
    proxy_pass http://dokuwiki;
  }

}

That's it :)
