Accessing Node-RED

Open uw browser en ga naar: https://<SERVER_IP>
Er wordt een SSL-waarschuwing in de browser verwacht (zelfondertekend certificaat)
Verificatie is vereist (pop-upvenster voor Basic Auth)
Verificatiemethode: HTTP Basic Auth
Inloggegevens worden veilig opgeslagen in: /root/.cloudzy-creds

Belangrijke bestanden en mappen

Main installation directory is /root/node-red.
Docker orchestration file is /root/node-red/docker-compose.yml.
Persistent Node-RED data is stored in /var/lib/docker/volumes/node-red_node-red-data/_data.
Nginx configuration file is located at /etc/nginx/sites-available/node-red.
Basic authentication credentials are stored in /etc/nginx/auth/node-red.htpasswd.
TLS certificates are stored in /etc/nginx/ssl.

Servicemanagement

Controleer de status van de container:

docker ps

Logs bekijken:

docker compose -f /root/node-red/docker-compose.yml logs -f

Restart Node-RED:

docker compose -f /root/node-red/docker-compose.yml restart

Start Nginx opnieuw op:

systemctl restart nginx

Node-RED Admin User (Alternative to Basic Auth)

Node-RED has its own internal authentication system, which can replace HTTP Basic Auth.

1. Locate `settings.js`

The main configuration file is inside the Node-RED Docker volume: /var/lib/docker/volumes/node-red_node-red-data/_data/settings.js

2. Enable `adminAuth`

Open settings.js and uncomment (or add) the adminAuth section. It should look something like this:

  adminAuth: {
      type: "credentials",
      users: [
          {
              username: "admin",
              password: "<HASHED_PASSWORD>",
              permissions: "*"
      }]
  },

3. Generate a password hash

You can generate the hash from inside the Node-RED container:

docker exec -it node-red-node-red-1 node-red admin hash-pw

You will be prompted to enter your plain password.

Copy the resulting hash and paste it as the password value in settings.js.

4. Restart Node-RED

After editing settings.js:

docker compose -f /root/node-red/docker-compose.yml restart

5. Disable HTTP Basic Auth in Nginx (Optional)

Edit the Nginx site file: /etc/nginx/sites-available/node-red

Remove or comment out these lines:

auth_basic "Restricted";
auth_basic_user_file /etc/nginx/auth/node-red.htpasswd;

Nginx opnieuw laden:

systemctl restart nginx

SSL inschakelen met een domein

1. Wijs uw domein naar het IP-adres van de server.

2. Bewerk de Nginx-configuratie en vervang beide server_name <IP>; met uw domein (<your-domain>) voor zowel HTTP (poort 80) als HTTPS (poort 443) blokken:

vim /etc/nginx/sites-available/node-red

3. Certbot installeren:

apt install -y certbot python3-certbot-nginx

4. Voer de volgende opdracht uit om een geldig Let’s Encrypt-certificaat te genereren:

certbot certonly --nginx --non-interactive --agree-tos --email [email protected] -d yourdomain.com

5. Vervang SSL-paden in Nginx-configuratie:

vim /etc/apache2/sites-available/node-red
# Before:
    # ssl_certificate /etc/nginx/ssl/fullchain.pem;
    # ssl_certificate_key /etc/nginx/ssl/privkey.pem;
# After:
    # ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
    # ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem;

6. Start Nginx opnieuw op om de wijzigingen toe te passen:

systemctl restart nginx

7. Open uw browser en ga naar: https://yourdomain.com
