This guide deploys Oxy on a single EC2 instance using oxy start, which manages PostgreSQL and the Oxy process for you.

​
1. Launch an EC2 instance

In the AWS Console → EC2 → Launch instance:
SettingValue
AMIUbuntu 22.04 LTS (64-bit ARM or x86)
Instance typet4g.medium (ARM, 2 vCPU, 4 GB) — or t3.medium for x86
Storage20 GB gp3
Security groupAllow SSH (22), HTTP (80), and port 3000 inbound
Note the Public IPv4 address once the instance is running.

​
2. Connect and install

SSH into your instance, then install Docker and Oxy: 
ssh -i your-key.pem ubuntu@YOUR_PUBLIC_IP

# Install Docker
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker $USER
newgrp docker

# Install Oxy
curl --proto '=https' --tlsv1.2 -sSf https://get.oxy.tech | sh

​
3. Set up your project

# Clone existing project
git clone https://github.com/your-org/your-oxy-project.git
cd your-oxy-project

# Or initialize a new one
mkdir my-oxy && cd my-oxy
oxy init

​
4. Start Oxy

oxy start
oxy start launches PostgreSQL in Docker and starts the Oxy server. Your instance is now running at http://YOUR_PUBLIC_IP:3000.
To keep Oxy running after you close your SSH session, use a terminal multiplexer:
screen -S oxy
oxy start
# Detach with Ctrl+A, D

​
5. (Optional) Use an external database for production

When you’re ready to use a managed database instead of the Docker-managed PostgreSQL: 
export OXY_DATABASE_URL="postgresql://user:password@your-rds-host:5432/oxy"
oxy serve
Use Amazon RDS for PostgreSQL for a fully managed option with automated backups and Multi-AZ support.
