This Docker image is built on Chainguard's Wolfi⁠, a security-focused, minimal Linux distribution designed for containers.

⁠Setup

required: set env DERP_DOMAIN to your domain

docker run -e DERP_DOMAIN=derper.your-domain.com -p 80:80 -p 443:443 -p 3478:3478/udp rgv151/derper

env	required	description	default value
DERP_DOMAIN	true	derper server hostname	your-hostname.com
DERP_CERT_DIR	false	directory to store LetsEncrypt certs(if addr's port is :443)	/app/certs
DERP_CERT_MODE	false	mode for getting a cert. possible options: manual, letsencrypt	letsencrypt
DERP_ADDR	false	listening server address	:443
DERP_STUN	false	also run a STUN server	true
DERP_STUN_PORT	false	The UDP port on which to serve STUN.	3478
DERP_HTTP_PORT	false	The port on which to serve HTTP. Set to -1 to disable	80
DERP_VERIFY_CLIENTS	false	verify clients to this DERP server through a local tailscaled instance	false
DERP_VERIFY_CLIENT_URL	false	if non-empty, an admission controller URL for permitting client connections	""

⁠Docker Compose Example

Here's a complete Docker Compose example for easy deployment:

services:
  derper:
    image: rgv151/derper:latest
    container_name: derper
    restart: unless-stopped
    ports:
      - "80:80"
      - "443:443"
      - "3478:3478/udp"
    environment:
      - DERP_DOMAIN=derper.your-domain.com
      - DERP_CERT_DIR=/app/certs
      - DERP_CERT_MODE=letsencrypt
      - DERP_ADDR=:443
      - DERP_STUN=true
      - DERP_STUN_PORT=3478
      - DERP_HTTP_PORT=80
      - DERP_VERIFY_CLIENTS=false
    volumes:
      - derper_certs:/app/certs
      # Uncomment the following line if using client verification
      # - /var/run/tailscale/tailscaled.sock:/var/run/tailscale/tailscaled.sock
    networks:
      - derper_network

volumes:
  derper_certs:
    driver: local

networks:
  derper_network:
    driver: bridge

To deploy:

# Update DERP_DOMAIN in the compose file
docker-compose up -d

⁠Usage

Fully DERP setup offical documentation: https://tailscale.com/kb/1118/custom-derp-servers/⁠

⁠Client verification

In order to use DERP_VERIFY_CLIENTS, the container needs access to Tailscale's Local API, which can usually be accessed through /var/run/tailscale/tailscaled.sock. If you're running Tailscale bare-metal on Linux, adding this to the docker run command should be enough: -v /var/run/tailscale/tailscaled.sock:/var/run/tailscale/tailscaled.sock
