To have a small and nice Wiki running, i am using Dokuwiki by Splitbrain https://github.com/dokuwiki/docker

I would not recommend to bind the wiki directly to the internet, but rather use Caddy for setting up SSL (see other section here) and to proxy the requests, so i will not open SSL port in this container.

To go for Dokuwiki: Create a folder in your Composer- Directory named e.g. „dokuwiki“. Place the file docker-compose.yml in it with the Content:

# src: https://github.com/dokuwiki/docker/blob/main/docker-compose.yml
services:
  dokuwiki:
    image: dokuwiki/dokuwiki:stable # other tags: master, <date> or <codename>
#    user: "1001:1001" # adjust to your required user id
    restart: always
#    ports:
#      - "8080:8080" # internal port is 8080, map to what you need
    environment:
      PHP_TIMEZONE: Europe/Berlin
      #PHP_MEMORYLIMIT: 256M
      #PHP_UPLOADLIMIT: 128M
    volumes:
      - dokuwiki_data:/storage
    networks:
      - default

volumes:
  dokuwiki_data:

# Still needs to be defined while without it won't enable ipv6
networks:
  default:
    driver: bridge
    enable_ipv6: true

Start the Service in the directory with docker compose up -d

Than, got to your Caddy- Directory and add a redirect to the file as always:

#dokuwiki
https://dokuwiki.domain.tld:443 {
        header Strict-Transport-Security max-age=31536000;
        reverse_proxy projectname-dokuwiki-1:8080
}

Restart the caddy-service with docker

After all, go to https://dokuwiki.domain.tld/install.php an finisch the setup of your dokuwiki

You are set!
