Secure Remote Access to DigitalOcean with Netmaker

Securing remote access to your DigitalOcean droplet with Netmaker can significantly enhance the security and management of your network. Netmaker is an open-source network management solution that allows you to create secure, scalable, and high-performance virtual private networks (VPNs) using WireGuard. Below is a step-by-step guide to setting up Netmaker to secure remote access to your DigitalOcean droplets:

1. Create a Droplet:
   • Log in to your DigitalOcean account.
   • Create a new droplet using Ubuntu 22.04 LTS.
   • Choose a droplet size appropriate for your needs (2GB RAM is a good starting point).
   • Add your SSH key for secure access.
   • Choose a data center region.
   • Click "Create Droplet".
2. Access Your Droplet:
   • Open a terminal on your local machine.
   • Connect to your droplet using its IP address:

                         
                             ssh root@your_droplet_ip
                         
                     

1. Update Your System:

                   
                       sudo apt update
                       sudo apt upgrade -y                    
                   
               

2. Install Docker:

                   
                       sudo apt install -y docker.io
                       sudo systemctl start docker
                       sudo systemctl enable docker                    
                   
               

3. Install Docker Compose:

                   
                       sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
                       sudo chmod +x /usr/local/bin/docker-compose                    
                   
               

1. Clone the Netmaker Repository:

                   
                       git clone https://github.com/gravitl/netmaker.git
                       cd netmaker                    
                   
               

2. Configure Environment Variables:
   • Create an .env file in the root of the netmaker directory and populate it with the necessary environment variables:

                       
                           nano .env
                       
                   

3. Example .env configuration:

                   
                       SERVER_NAME=netmaker
                       SERVER_IP=your_droplet_ip
                       SERVER_PORT=443
                       API_PORT=8081
                       DASHBOARD_PORT=8082
                       MQ_USERNAME=netmaker
                       MQ_PASSWORD=changeme                    
                   
               

4. Start Netmaker with Docker Compose:

                   
                       sudo docker-compose up -d
                   
               

1. Install WireGuard:
   • On Ubuntu:

                             
                                 sudo apt install wireguard
                             
                         

   • On macOS:

                             
                                 brew install wireguard-tools
                             
                         

   • On Windows:

     Download and install WireGuard from the official website.

2. Generate WireGuard Keys:

                   
                       wg genkey | tee privatekey | wg pubkey > publickey
                   
               

3. Configure WireGuard Client:
   • Create a configuration file (e.g., wg0.conf):
4. Example wg0.conf:

                   
                       [Interface]
                       PrivateKey = your_private_key
                       Address = 10.0.0.2/24
                       DNS = 1.1.1.1
                       
                       [Peer]
                       PublicKey = server_public_key
                       Endpoint = your_droplet_ip:51820
                       AllowedIPs = 0.0.0.0/0
                       PersistentKeepalive = 21                    
                   
               

5. Start WireGuard:
   • On Ubuntu/macOS:

                             
                                 sudo wg-quick up wg0
                             
                         

   • On Windows:
     • Import the wg0.conf file into the WireGuard application and activate the tunnel.

1. Access Netmaker Dashboard:
   • Open a web browser and navigate to https://your_droplet_ip:8082.
   • Log in with the default credentials or the ones you configured.
2. Add Machines to the Network:
   • Use the Netmaker dashboard to add new nodes (machines) to your WireGuard network.
   • Follow the instructions provided in the Netmaker documentation to securely connect additional devices.

1. Enable UFW Firewall:

                   
                       sudo ufw allow OpenSSH
                       sudo ufw allow 443/tcp
                       sudo ufw allow 51820/udp
                       sudo ufw enable                    
                   
               

2. Set Up SSL with Let’s Encrypt:
   • Install Certbot:

                             
                                 sudo apt install certbot
                                 sudo apt install python3-certbot-nginx                            
                             
                         

   • Obtain an SSL certificate:

                             
                                 sudo certbot --nginx -d your_domain  
                             
                         

3. Configure Nginx for SSL:
   • Edit the Nginx configuration to use the obtained SSL certificate:

                       
                           sudo nano /etc/nginx/sites-available/default
                       
                   

   • Ensure the configuration includes:

                             
                                 server {
                                     listen 443 ssl;
                                     server_name your_domain;
                                 
                                     ssl_certificate /etc/letsencrypt/live/your_domain/fullchain.pem;
                                     ssl_certificate_key /etc/letsencrypt/live/your_domain/privkey.pem;
                                 
                                     location / {
                                         proxy_pass http://localhost:8082;
                                         proxy_set_header Host $host;
                                         proxy_set_header X-Real-IP $remote_addr;
                                         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                                         proxy_set_header X-Forwarded-Proto $scheme;
                                     }
                                 }                             
                             
                         

4. Restart Nginx:

                   
                       sudo systemctl restart nginx
