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

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

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.
