One droplet to manage forwarding to other droplets

Hi there,

Indeed, Nginx sounds like a good option.

What you could do is to setup an Nginx server block for each of your domain names with the corresponding reverse proxy rules.

For example:

• In /etc/nginx/sites-available/service1.domain.com:

server{
    listen 80;
    server_name service1.domain.com;
    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_pass http://your_droplet1_ip:8017;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        # location /overview {
        #     proxy_pass http://your_droplet1_ip:8017$request_uri;
        #     proxy_redirect off;
        # }
    }
}

• In /etc/nginx/sites-available/service2.domain.com:

server{
    listen 80;
    server_name service2.domain.com;
    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_pass http://your_droplet2_ip:8018;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        # location /overview {
        #     proxy_pass http://your_droplet2_ip:8018$request_uri;
        #     proxy_redirect off;
        # }
    }
}

And so on for each domain name.

Then you could use Let’s Encrypt to issue a certificate for your domains.

You should be able to also achieve this without the need of a separate Nginx Droplet, you could have the same result with the Nginx installed on the Droplets where you’ve deployed your apps on.

Let me know how it goes and let me know if you have any questions!

Best,

Bobby
