Overview

Infisical is a secure secret management platform that GAIA uses to centrally manage environment variables and API keys. Instead of storing sensitive information in .env files, Infisical allows you to:
  • Centrally manage secrets across multiple environments
  • Secure access controls with role-based permissions
  • Audit logging for secret access and changes
  • Automatic secret rotation capabilities
  • Team collaboration with shared secret access
When Infisical is configured, it will override any local environment variables with the same names from your Infisical project.

​
How Infisical Works with GAIA

GAIA’s backend automatically loads secrets from Infisical during startup using the inject_infisical_secrets() function. Here’s the process:
  1. Authentication: Uses machine identity credentials to authenticate with Infisical
  2. Secret Retrieval: Fetches all secrets from your Infisical project
  3. Environment Injection: Overwrites local environment variables with Infisical secrets
  4. Application Startup: GAIA starts with the combined environment configuration

​
Setting Up Infisical

​
Step 1: Create an Infisical Account

  1. Visit app.infisical.com
  2. Sign up for a free account
  3. Create a new project for GAIA

​
Step 2: Create a Machine Identity

Machine identities allow GAIA to authenticate with Infisical automatically:
  1. Go to Project Settings → Access Control → Machine Identities
  2. Click Create Identity
  3. Configure the identity:
    • Name: gaia-backend
    • Role: Admin or Developer (with read access to secrets)
  4. Note down the Client ID and Client Secret

​
Step 3: Add Secrets to Infisical

Navigate to your project’s Secrets section and add all your environment variables:

Core Application

ENV=production
DEBUG=false
HOST=https://api.heygaia.io
FRONTEND_URL=https://heygaia.io

Database URLs

POSTGRES_URL=postgresql://user:pass@host:5432/db
MONGO_DB=mongodb://user:pass@host:27017/gaia
REDIS_URL=redis://user:pass@host:6379

AI API Keys

OPENAI_API_KEY=sk-your-openai-key
GEMINI_API_KEY=your-gemini-key
HUGGINGFACE_API_KEY=hf_your-hf-token

Integration APIs

GOOGLE_CLIENT_ID=your-google-client-id
GOOGLE_CLIENT_SECRET=your-google-secret
BING_API_KEY=your-bing-key

​
Step 4: Configure GAIA Backend

Add the Infisical configuration to your backend .env file: 
# Infisical Configuration
INFISICAL_PROJECT_ID=your-project-id-from-infisical
INFISICAL_MACHINE_INDENTITY_CLIENT_ID=your-client-id
INFISICAL_MACHINE_INDENTITY_CLIENT_SECRET=your-client-secret

# Optional: Set environment (defaults to 'production')
ENV=development
The INFISICAL_PROJECT_ID, INFISICAL_MACHINE_INDENTITY_CLIENT_ID, and INFISICAL_MACHINE_INDENTITY_CLIENT_SECRET must be set in your local .env file - they cannot be stored in Infisical itself since they’re needed to authenticate with Infisical.

​
Environment Priority

GAIA loads environment variables in this order (later sources override earlier ones):
  1. System environment variables
  2. Local .env file variables
  3. Infisical secrets (highest priority)
This means:
  • ✅ Infisical secrets will override local .env variables
  • ✅ You can use local .env for development and Infisical for production
  • ✅ Critical secrets are managed centrally through Infisical

​
Development vs Production

​
Development Setup

For local development, you can choose between: Option A: Use Infisical (Recommended for teams) 
# backend/.env
ENV=development
INFISICAL_PROJECT_ID=your-dev-project-id
INFISICAL_MACHINE_INDENTITY_CLIENT_ID=your-client-id
INFISICAL_MACHINE_INDENTITY_CLIENT_SECRET=your-client-secret
Option B: Use Local Environment Variables 
# backend/.env
ENV=development
# Add all your environment variables here
OPENAI_API_KEY=your-local-dev-key
# ... other variables

​
Production Setup

For production, always use Infisical: 
# backend/.env (production)
ENV=production
INFISICAL_PROJECT_ID=your-prod-project-id
INFISICAL_MACHINE_INDENTITY_CLIENT_ID=your-prod-client-id
INFISICAL_MACHINE_INDENTITY_CLIENT_SECRET=your-prod-client-secret

​
Troubleshooting

​
Common Issues

​
Debug Mode

To debug Infisical integration, check the application logs during startup. The backend will log any Infisical connection issues.

​
Security Best Practices

Access Control

  • Use separate machine identities for different environments
  • Grant minimal required permissions
  • Regularly audit access logs

Secret Management

  • Use different secrets for dev/staging/production
  • Rotate secrets regularly
  • Never commit Infisical credentials to version control

Environment Separation

  • Use separate Infisical projects for each environment
  • Implement proper CI/CD secret injection
  • Monitor secret access patterns

Backup Strategy

  • Export secrets regularly for backup
  • Document secret recovery procedures
  • Have fallback authentication methods
