Simple self-hosted using docker-compose

Note: This config is currently missing a TURN server, so it won’t work if the clients can’t reach each other! I am working on this. is a new service similar to and inspired by magic-wormhole that allows easily sharing files between browsers without the need to install a software. Internally, it uses WebRTC, allowing direct transfer of files between computers even through firewalls.

While there is no official Docker image published on Docker Hub, the WebWormhole GitHub project provides an official Dockerfile. Based on this, I have published ulikoehler/webwormhole which has been built using

git clone
cd webwormhole
docker build -t ulikoehler/webwormhole:latest .
docker push ulikoehler/webwormhole:latest

This is the docker-compose.yml that you can use to run WebWormhole behind a reverse proxy:

version: '3'
    image: 'ulikoehler/webwormhole:latest'
    entrypoint: ["/bin/ww", "server", "-http=localhost:52618", "-https="]
    network_mode: host

and this is my nginx config:

server {

    access_log off;
    error_log /var/log/nginx/;

    location / {
        proxy_pass http://localhost:52618/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_redirect default;

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    #ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
server {
    if ($host = {
        return 301 https://$host$request_uri;


    listen 80;
    return 404; # managed by Certbot

I store docker-compose.yml in /var/lib/ and I used the script from our previous post Create a systemd service for your docker-compose project in 10 seconds in order to create this systemd config file in /etc/systemd/system/


# Shutdown container (if running) when unit is started
ExecStartPre=/usr/local/bin/docker-compose -f docker-compose.yml down
# Start container when unit is started
ExecStart=/usr/local/bin/docker-compose -f docker-compose.yml up
# Stop container when unit is stopped
ExecStop=/usr/local/bin/docker-compose -f docker-compose.yml down


which you can start and enable using

sudo systemctl enable
sudo systemctl start
