# Portainer Stack Backup Script

This script connects to a Portainer instance and exports all stacks with their configurations, environment variables, and docker-compose files.

## Prerequisites

- `curl` (usually pre-installed on macOS)
- `jq` for JSON processing: `brew install jq`

## Usage

1. Make sure the script is executable:
   ```bash
   chmod +x portainer-backup.sh
   ```

2. Run the script:
   ```bash
   ./portainer-backup.sh
   ```

3. When prompted, enter:
   - Portainer URL (e.g., `http://localhost:9000`)
   - Username
   - Password

Alternatively, you can edit the script and set these variables at the top:
```bash
PORTAINER_URL="http://your-portainer-url:9000"
USERNAME="your-username"
PASSWORD="your-password"
```

## Output

The script creates a `portainer-stacks-backup` directory containing:

```
portainer-stacks-backup/
├── stack-name-1/
│   ├── stack-info.json          # Complete stack information
│   ├── environment-variables.json # Environment variables as JSON
│   ├── .env                     # Environment variables in .env format
│   ├── docker-compose.yml       # Stack's compose file
│   └── metadata.txt             # Human-readable metadata
├── stack-name-2/
│   └── ...
```

## What gets backed up

For each stack:
- Complete stack configuration (JSON format)
- Environment variables (both JSON and .env formats)
- Docker Compose file content
- Metadata (creation date, status, type, etc.)

## Error Handling

The script includes error handling for:
- Missing dependencies
- Authentication failures
- Network connectivity issues
- API errors

## Security Note

The script handles authentication via JWT tokens. Passwords are prompted securely (hidden input) if not set in the script.
