Docker Compose

Here are basic and simple docker-compose configuration files that will enable you to quickly deploy your own instance manually. We also assume in this example, that all services will deployed on dedicated servers/VMs - separating them physically, thus each compose is for a separate service.

Please not that we also offer docker-compose deployment with one-line quick deployment, but this method is recommended for PoC/quick deployment as it launches everything on one server and all services in one docker compose.

We use "latest" (latest production images) tags in the examples below, but you can use others - more info here.

Core

Here is the docker-compose.yaml for the core and database. Configuration is split to the .env file (see below):

services:
  core:
    image: ghcr.io/defguard/defguard:latest
    restart: always
    container_name: "defguard"
    env_file: .env
    ports:
      # HTTP port - open on localhost, should be secured by reverse-proxy
      - "127.0.0.1:80000:8000"
      # gRPC port for gateway to connect to
      # open on all interfaces/IPs - whould be secured with custom CA (see .env)
      - "50055:50055"
    depends_on:
      - db
    volumes:
      # more info here:
      # https://docs.defguard.net/admin-and-features/setting-up-your-instance/openid-rsa-key
      - ./rsakey.pem:/keys/rsakey.pem
      # more info about custom CA here:
      # https://docs.defguard.net/admin-and-features/setting-up-your-instance/grpc-ssl-communication#custom-ssl-ca-and-certificates
      - ./ca.pem:/keys/ca.pem

  db:
    image: postgres:17-alpine
    container_name: "defguard-db"
    env_file: .env
    volumes:
      - db:/var/lib/postgresql/data

NGINX reverese-proxy

Now that you have core running here is an example NGINX configuration to provide SSL termination:

upstream  defguard {
    server 127.0.0.1:8000;
}

server {
    listen 443 ssl http2;

    # your domain
    server_name defguard.secure-internal.net;

    access_log /var/log/nginx/defguard.log;
    error_log /var/log/nginx/defguard.error.log;

    ssl on;
    # we assume you already have Let'sEncrypt SSL certificates
    # for your domain
    ssl_certificate /etc/letsencrypt/live/secure-internal.net/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/secure-internal.net/privkey.pem;

    client_max_body_size 20m;

    location / {
        proxy_connect_timeout 300;
        proxy_pass http://defguard;
        proxy_set_header Connection "upgrade";
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header X-Forwarded-for $remote_addr;
    }
}

The configuration

Here is the .env file with all configuration variables:

# please generate each secret with:
# openssl rand -base64 55 | tr -d "=+/" | tr -d '\n' | cut -c1-63
DEFGUARD_SECRET_KEY=
DEFGUARD_AUTH_SECRET=
DEFGUARD_GATEWAY_SECRET=
DEFGUARD_YUBIBRIDGE_SECRET=

# if you plan to reverse-proxy defguard, please provide a full URL
# this URL will be shared in emails, enrollement messages, etc.:
DEFGUARD_URL=https://defguard.secure-internal.net
# Must be an effective domain of DEFGUARD_URL
# Changing DEFGUARD_WEBAUTHN_RP_ID will potentially break all your existing
# Webauthn credentials.
DEFGUARD_WEBAUTHN_RP_ID=defguard.secure-internal.net

# accepted: info/debug/warning/error

# gRPC URL of proxy (see proxy config)
DEFGUARD_PROXY_URL=https://proxy.host:50051
# more details about RSA key here:

POSTGRES_USER=defguard
POSTGRES_PASSWORD=!SAME_AS-GENERATED-DEFGUARD_DB_PASSWORD!

Proxy

Here is the docker-compose.yaml for the public proxy (enrollment service as well as desktop client configuration service).

To secure the gRPC communication please generate the proxy CA and certificate, more info here.

proxy:
  image: ghcr.io/defguard/defguard-proxy:latest
  restart: unless-stopped
  ports:
     # HTTP port - should be secured by reverse proxy
     - "127.0.0.1:8080:8080"
     - "50051:50051"
  environment:
     # path in the volume to custom proxy cert & key
     - DEFGUARD_PROXY_GRPC_CERT=ca/proxy.crt
     - DEFGUARD_PROXY_GRPC_KEY=ca/proxy.key     
  volumes:
     - ./ca/proxy.crt:ca/proxy.crt
     - ./ca/proxy.key:ca/proxy.key
  

NGINX reverese-proxy

Now that you have proxy running here is an example NGINX configuration to provide SSL termination:

upstream  defguard-proxy  {
	server   127.0.0.1:8080;
}

server {
	listen 443 http2;
	server_name enrollment.public.net;
	access_log /var/log/nginx/defguard-proxy.log;
	error_log /var/log/nginx/defguard-proxy.error.log;

        # we assume you already have Let'sEncrypt SSL certificates
        # for your domain
	ssl_certificate /etc/letsencrypt/live/public.net/fullchain.pem;
	ssl_certificate_key /etc/letsencrypt/live/public.net/privkey.pem;

	client_max_body_size 20m;

        location / {
            proxy_pass         http://defguard-proxy;
            proxy_set_header   Host             $host;
            proxy_set_header   X-Real-IP        $remote_addr;
            proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        }
}

Gateway

For gateway to control the WireGuard kernel as well as network, it's recommended to run in the host network mode as well as there are needed some docker CAPs:

services:
  gateway: 
    image: ghcr.io/defguard/gateway:latest 
    restart: unless-stopped 
    network_mode: "host" 
    environment: 
      - DEFGUARD_GRPC_URL=https://core-ip:50055
      - DEFGUARD_GRPC_CA=/ca.pem
      - DEFGUARD_STATS_PERIOD=30
      # to get the token add a VPN location and get the token
      - DEFGUARD_TOKEN=tokenFromCoreLocation
      - DEFGUARD_GATEWAY_NAME=willBeVisibleInDefguardAsGWName
    volumes:
      # more info about custom CA here:
      # https://docs.defguard.net/admin-and-features/setting-up-your-instance/grpc-ssl-communication#custom-ssl-ca-and-certificates
      - ./ca.pem:/ca.pem
    cap_add: 
      - NET_ADMIN
