TSDProxy - Tailscale Docker Proxy

The easiest way to expose Docker containers on your Tailscale network. One label. Zero sidecars.

Quick Start

Get running in under a minute. One compose file, one label.

Step 1: Create docker-compose.yml

services:
  tsdproxy:
    image: almeidapaulopt/tsdproxy:2
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - tsdproxy-data:/data
      - ./config:/config
    ports:
      - "8080:8080"
    extra_hosts:
      - "host.docker.internal:host-gateway"
    restart: unless-stopped

  myapp:
    image: nginx:alpine
    labels:
      tsdproxy.enable: "true"
      tsdproxy.name: "myapp"

volumes:
  tsdproxy-data:

Step 2: Start it up

docker compose up -d

TSDProxy creates a default config at /config/tsdproxy.yaml on first run. Open the dashboard at http://localhost:8080, click the proxy card, and authenticate with Tailscale.

Your container is now available at https://myapp.<tailnet-name>.ts.net with automatic HTTPS.

For automated (headless) setup, configure an AuthKey or OAuth before adding services.

Key Features

Feature	Description
Zero sidecars	No Tailscale container needed per service. One proxy handles everything.
Label-based config	Add tsdproxy.enable=true to any container. Done.
Automatic HTTPS	Tailscale provisions Let's Encrypt certs for every machine.
Multi-port support	Expose multiple ports per container with granular protocol control.
TCP & UDP proxying	Proxy TCP (SSH, databases) and UDP traffic alongside HTTP/HTTPS services.
Port ranges	Define ranges of ports in a single label — e.g. 2222-2230/tcp.
Funnel support	Expose services to the public internet with tailscale_funnel option.
Health monitoring	Automatic backend health probes with recovery and target re-resolution.
Webhook notifications	Push proxy events to ntfy, Discord, Slack, Gotify, or generic webhooks.
REST API	Programmatic control over proxies — pause, resume, and manage via API.
Role-based access	Admin and viewer roles with optional admin allowlist.
Dynamic lifecycle	Containers start and stop. Tailscale machines appear and disappear.
Live config reload	Change settings without restarting TSDProxy.
Dashboard	Real-time web UI with SSE streaming, access logs, and status timeline.
List provider	Expose non-Docker services via a simple YAML file.

How It Works

graph LR
    A[Docker Containers] -->|tsdproxy.enable label| B[TSDProxy]
    B -->|creates tsnet.Server| C[Tailscale Network]
    C -->|automatic HTTPS| D[Secure URLs]
    D -->|reverse proxy| A

Under the hood:

1. Container Scanning - TSDProxy watches your Docker daemon for containers tagged with tsdproxy.enable=true.
2. Machine Creation - When a tagged container appears, TSDProxy spins up a Tailscale machine via tsnet.
3. Hostname Assignment - The machine gets a hostname from the tsdproxy.name label or the container name.
4. Port Mapping - TSDProxy maps the container's internal port to the Tailscale machine.
5. Traffic Routing - Incoming requests to https://myapp.<tailnet>.ts.net are reverse-proxied to the container.
6. Dynamic Cleanup - When a container stops, its Tailscale machine and routes are removed automatically.

Port Configuration

Expose multiple ports with per-port protocol and options:

labels:
  tsdproxy.enable: "true"
  tsdproxy.name: "myservice"

  # HTTPS on 443 -> container port 80
  tsdproxy.port.1: "443/https:80/http"

  # HTTP on 80 -> container port 8080
  tsdproxy.port.2: "80/http:8080/http"

  # HTTP redirect to HTTPS
  tsdproxy.port.3: "81/http->https://myservice.tailnet.ts.net"

  # TCP proxy for SSH
  tsdproxy.port.4: "22/tcp:22/tcp"

  # UDP proxy (e.g. game server, VoIP)
  tsdproxy.port.5: "5060/udp:5060/udp"

  # Port range (TCP ports 2222 through 2230)
  tsdproxy.port.6: "2222-2230/tcp:2222-2230/tcp"
