# CZDS Docker Compose Setup

This repository contains a Docker Compose setup for running a CZDS (Centralized Zone Data Service) application that downloads the latest zonefiles alongside a PostgreSQL database.

## Overview

The `docker-compose.yml` file defines two services:

- `czds`: The application service, which is built from a Dockerfile named `Dockerfile.czds`. It depends on the `db` service and is configured with necessary environment variables for database access and application credentials.
- `db`: A PostgreSQL database service, using the official `postgres:13` image. It is configured with a default user, password, and database name, and stores data in a volume for persistence.

## Prerequisites

- Docker
- Docker Compose

Ensure Docker and Docker Compose are installed and running on your system.

## Getting Started

1. **Clone the Repository**

   Clone this repository to your local machine using:

   ```bash
   git clone <repository-url>
   ```

2. **Build and Run Services**

   Navigate to the cloned repository directory and run the following command to build and start the services:

   ```bash
   docker-compose up --build
   ```

   This command builds the `czds` service using the specified Dockerfile and starts both the `czds` and `db` services.

3. **Accessing the Application**

   Once the services are up and running, the CZDS application will be accessible. Refer to the application's documentation for details on accessing and using it.
   ```bash
    docker exec -it czd-czds-1  bash
   ```
   -------
   ```
   docker exec -it czd-db-1 psql -U postgres -d czds
   ```

4. **Stopping Services**

   To stop the running services, use the following command:

   ```bash
   docker-compose down --rmi all
   ```

## Configuration

- **Environment Variables**: The `czds` service requires certain environment variables to be set for database access and authentication. These can be modified in the `docker-compose.yml` file.
- **Volumes**: Data persistence is managed through Docker volumes. The `db` service stores its data in `./db-data`, and the `czds` service stores its data in `./zones`. These paths can be adjusted as needed.
