Gemini Service Account Example

Example GCP project setup demonstrating how to access Gemini via Vertex AI using service account authentication with proper security configuration.
This reference implementation shows the correct way to set up service accounts, IAM permissions, and authentication flows for production Gemini deployments.
What This Solves
Many developers struggle with authenticating to Vertex AI Gemini APIs from applications, especially in production environments. This example provides:
- Service account configuration - Proper IAM roles and permissions
- Authentication flow - How to generate and use credentials
- Security best practices - Least-privilege access, key rotation
- Production patterns - Environment-specific configuration
