Configuracion

Configure InstaTunnel with config files and environment variables for persistent settings.

📁 Configuration Files

Global Configuration

Create a global config file at ~/.instatunnel.yaml:

# ~/.instatunnel.yaml

api_key: "your_api_key_here"

server_url: "https://api.instatunnel.my"

💡 Tip: Config file is automatically loaded if present in your home directory.

Custom Config File

Use a custom config file location with the --config flag:

# Use custom config file

$ instatunnel --config /path/to/config.yaml 3000

Using config file: /path/to/config.yaml

✅ Tunnel created: https://abc123.instatunnel.my

🌍 Environment Variables

Available Environment Variables

InstaTunnel automatically reads environment variables that match config keys:

# Set your API key

$ export API_KEY="your_api_key_here"

# Set custom server URL

$ export SERVER_URL="https://api.instatunnel.my"

# Now these are used automatically

$ instatunnel 3000

🔒 Security: Never commit API keys to version control. Use environment variables for sensitive data.

⚙️ Configuration Priority

InstaTunnel follows this configuration priority (highest priority first):

Command-line flags - --api-key your_key
Environment variables - API_KEY=your_key
Config file - ~/.instatunnel.yaml
Built-in defaults - Fallback values

# Example: Command-line flag overrides everything

$ instatunnel --api-key override_key 3000

✅ Using API key from command line

🛠 Available Configuration Options

Current Options

Option	Flag	Env Variable	Description
`api_key`	`--api-key`	`API_KEY`	Your InstaTunnel API key
`server_url`	`--server`	`SERVER_URL`	InstaTunnel server URL

🎯 Best Practice: Store your API key in the config file (~/.instatunnel.yaml) or environment variable for convenience. Use command-line flags for temporary overrides.
