Self-hosting on DigitalOcean

1. Create the server

Create a Droplet → Ubuntu 24.04 → Basic / Regular → the 4 GB / 2 vCPU plan (~$24/mo) → choose the region nearest your hotel → add your SSH key. The droplet's IP appears on creation.

2. Point your domain

Add an A record for pms.yourhotel.com → the server's IP at your DNS provider. (If you use Cloudflare, set it to DNS only while issuing the SSL certificate.)

3. Install Docker

ssh root@<server-ip>
curl -fsSL https://get.docker.com | sh

4. Install Kamra

From here it's identical everywhere — follow the Quickstart: build the image with Kamra in apps.json, bring the compose stack up, create your site, enable the scheduler.

5. SSL

apt install -y certbot python3-certbot-nginx
certbot --nginx -d pms.yourhotel.com

Then work through the production checklist.
