## Environment Variables
| Variable | Description | Default |
| ------------------- | ---------------------------------------------------------- | --------------------------------- |
| `BLOCK_COUNTRIES` | Comma-separated country codes to block (e.g., `CN,RU,IR`) | (required) |
| `BLOCKLIST_CRON` | Cron expression for update frequency (e.g., `0 6 * * *`) | `0 6 * * *` (at 6:00 everydays) |
| `DOCKER_API_URL` | URL of Docker socket proxy to restart AdGuard container | `http://docker-socket-proxy:2375` |
## File Structure
- `update-blocklist.sh`: Main script to download CIDRs, merge manual IPs, update config, and restart AdGuard.
- `entrypoint.sh`: Sets up the cron job to periodically run the update script.
- `Dockerfile`: Builds the lightweight Alpine-based image.
- `docker-compose.yml`: Example compose file to run the container.
- `manually_blocked_ips.conf`: (Volume mount) Add extra IPs to block manually.
## Installation and Usage
1. **Clone the repository:**
```bash
git clone https://git.djeex.fr/Djeex/adguard-cidre
cd adguard-cidre
```
2. **Modify docker-compose.yml**
- Set `BLOCK_COUNTRIES` environment variable with the countries you want to block.
- Adjust `BLOCKLIST_CRON` if you want a different update frequency.
- Bind mount your adguard configuration folder (wich contains `AdGuardHome.yaml`) to `/adguard`
- (optionnally) create and edit `manually_blocked_ips.conf` file in your adguard configuration folder to add other IPs you want to block. Only valid IP or CIDR entries will be processed, for exemple :
```bash
192.168.1.100
10.0.0.0/24
# Comments or empty lines are ignored
```
4. **Build and start the container**
```bash
docker-compose build
docker-compose up -d
```
5. **Check logs to verify updates**
```bash
docker-compose logs -f
```
