View source for Wireguard - Docker

== Install Wireguard ==
This is a quick start guide to get you up and running with WireGuard Easy.

The easiest way to run WireGuard Easy is with Docker Compose.

Create <code>docker-compose.yml</code> and execute <code>sudo docker compose up -d</code><syntaxhighlight lang="bash">
volumes:
  etc_wireguard:

services:
  wg-easy:
    #environment:
    #  Optional:
    #  - PORT=51821
    #  - HOST=0.0.0.0
    #  - INSECURE=false

    image: ghcr.io/wg-easy/wg-easy:15
    container_name: wg-easy
    networks:
      wg:
        ipv4_address: 10.42.42.42
        ipv6_address: fdcc:ad94:bacf:61a3::2a
    volumes:
      - etc_wireguard:/etc/wireguard
      - /lib/modules:/lib/modules:ro
    ports:
      - "51820:51820/udp"
      - "51821:51821/tcp"
    restart: unless-stopped
    cap_add:
      - NET_ADMIN
      - SYS_MODULE
      # - NET_RAW # ⚠️ Uncomment if using Podman
    sysctls:
      - net.ipv4.ip_forward=1
      - net.ipv4.conf.all.src_valid_mark=1
      - net.ipv6.conf.all.disable_ipv6=0
      - net.ipv6.conf.all.forwarding=1
      - net.ipv6.conf.default.forwarding=1

networks:
  wg:
    driver: bridge
    enable_ipv6: true
    ipam:
      driver: default
      config:
        - subnet: 10.42.42.0/24
        - subnet: fdcc:ad94:bacf:61a3::/64
</syntaxhighlight>Now setup a reverse proxy to be able to access the Web UI securely from the internet.

If you want to access the Web UI over HTTP, change the env var <code>INSECURE</code> to <code>true</code>. This is not recommended. Only use this for testing.

== Secure Connection ==

===== Pastikan DNS domain sudah mengarah ke server =====
Pastikan <code>vpn.deffcon.com</code> sudah mengarah ke IP publik server Anda (<code>103.250.10.5</code>):

* Login ke penyedia domain Anda.
* Tambahkan record DNS type <code>A</code>:
** '''Host:''' <code>track</code>
** '''Value / IP:''' <code>103.250.10.5</code>

Tunggu propagasi DNS beberapa menit (hingga 1 jam tergantung provider).

===== Instal Nginx =====
 sudo apt update
 sudo apt install nginx -y

===== Konfigurasi Nginx untuk reverse proxy =====
Buat file konfigurasi baru untuk domain Anda di <code>/etc/nginx/sites-available/vpn.deffcon.com</code>:<syntaxhighlight lang="bash" line="1">
server {
    listen 80;
    server_name vpn.deffcon.com;

    location / {
        proxy_pass http://localhost:51821/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}
</syntaxhighlight>'''PORT 51821''' adalah port Wireguard di dalam Docker secara default

Kemudian aktifkan konfigurasi dengan perintah:
 sudo ln -s /etc/nginx/sites-available/vpn.deffcon.com /etc/nginx/sites-enabled/
Cek konfigurasi & restart Nginx
 sudo nginx -t
 sudo systemctl restart nginx<br />

===== Tambahkan HTTPS dengan Let's Encrypt =====
Agar lebih aman, gunakan SSL via Certbot:
 sudo apt install certbot python3-certbot-nginx -y
 sudo certbot --nginx -d vpn.deffcon.com
Simpan dan restart Nginx
 sudo systemctl restart nginx

===== Auto-Renewal SSL =====
Let's Encrypt sertifikat berlaku 90 hari. Certbot biasanya sudah otomatis membuat cronjob untuk perpanjangan.

Cek dengan:
 sudo certbot renew --dry-run

===== Uji Coba SSL =====
Pergi ke alamat <code>vpn.deffcon.com</code> , apakah sudah terencrypt SSL atau belum.
