Environment Variables

The authentication system uses environment variables for configuration. These variables allow for flexible deployment across different environments.

Key Environment Variables

1. TOKEN_URL

   • Purpose: Specifies the URL of the external authentication service used for token validation.
   • Required: Yes
   • Example: https://auth.example.com/validate

2. TOKEN_CACHE_EXPIRY

   • Purpose: Sets the expiration time for cached tokens.
   • Usage: Parsed in the init() function of token.go
   • Required: No (defaults to 5 minutes if not set)
   • Example: 15m for 15 minutes, 1h for 1 hour

Setting Environment Variables

In Development

Use a .env file in the project root:

TOKEN_URL=https://auth.example.com/validate
TOKEN_CACHE_EXPIRY=10m

In Production

Set environment variables according to your deployment platform:

• Docker: Use the -e flag or environment section in docker-compose.yml
• Kubernetes: Use ConfigMap and Secret resources
• Cloud Platforms: Use the platform-specific method for setting environment variables
