-description: "Configure SQLite or PostgreSQL database for Pangolin"
----
-
-## Overview
-
-> Choose between SQLite (default) or PostgreSQL for your database
-
-Pangolin supports two database options: SQLite for simplicity and PostgreSQL for production deployments.
-
-<CardGroup cols={2}>
-<Card title="SQLite (Default)" icon="database">
-  - No configuration required
-  - Easy to use and portable
-  - Built into the main image
-  - Perfect for development
-</Card>
-
-<Card title="PostgreSQL" icon="postgres">
-  - Production-ready database
-  - Better performance at scale
-  - Requires separate image
-  - Advanced configuration options
-</Card>
-</CardGroup>
-
-## SQLite
-
-By default, Pangolin uses SQLite for its ease of use and portability.
-
-**Docker Image**: `fosrl/pangolin:<version>`
-
-<Note>
-No configuration is required to use SQLite with Pangolin.
-</Note>
-
-## PostgreSQL
-
-You can optionally use PostgreSQL for production deployments.
-
-**Docker Image**: `fosrl/pangolin:postgresql-<version>`
-
-### Configuration
-
-Add the following section to your Pangolin configuration file:
-
-```yaml title="config.yml"
-postgres:
-  connection_string: postgresql://<user>:<password>@<host>:<port>/<database>
-```
-
-<Warning>
-Replace the placeholders with your actual PostgreSQL connection details.
-</Warning>
-
-### Docker Compose Example
-
-This example sets up PostgreSQL with health checks to ensure the database is ready before Pangolin starts:
-
-```yaml title="docker-compose.yml"
-name: pangolin
-services:
-  pangolin:
-    image: fosrl/pangolin:postgresql-latest
-    container_name: pangolin
-    restart: unless-stopped
-    depends_on:
-      postgres:
-        condition: service_healthy
-    volumes:
-      - ./config:/app/config
-    healthcheck:
-      test: ["CMD", "curl", "-f", "http://localhost:3001/api/v1/"]
-      interval: "10s"
-      timeout: "10s"
-      retries: 15
-
-  postgres:
-    image: postgres:17
-    container_name: postgres
-    restart: unless-stopped
-    environment:
-      POSTGRES_USER: postgres
-      POSTGRES_PASSWORD: postgres
-    volumes:
-      - ./config/postgres:/var/lib/postgresql/data
-    healthcheck:
-      test: ["CMD-SHELL", "pg_isready -U postgres"]
-      interval: 10s
-      timeout: 5s
-      retries: 5
-```
-
-<Warning>
-This example is not necessarily production-ready. Adjust the configuration according to your needs and security requirements.
-</Warning>
-
-<Note>
-Do not use `latest` tags in production. Use specific version tags for stability.
