Self-hosting on AWS

1. Create the server

In EC2, Launch instance → Ubuntu Server 24.04 → t3.medium (2 vCPU / 4 GB, ~$30/mo with EBS) → 40 GB gp3 volume → a security group allowing ports 22, 80, 443 → attach an Elastic IP so the address survives restarts.

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.
