Environment Configuration Guide

This project uses a .env file to manage configuration for local and remote testing.

Quick Start

Install python-dotenv:
```
pip install python-dotenv
```
Edit .env file:
```
nano .env
```
Toggle between local/remote:
```
./toggle_env.sh
```

Configuration Options

Ollama Server Settings

OLLAMA_HOST - Server hostname (default: localhost)
OLLAMA_PORT - Server port (default: 11434)
OLLAMA_MODEL - Default model name (default: llama3:latest)
OLLAMA_WORK_MODEL - Work agent model (default: llama3:latest)
OLLAMA_FAMILY_MODEL - Family agent model (default: llama3:latest)

Environment Toggle

ENVIRONMENT - Set to local or remote (default: local)

Feature Flags

ENABLE_DASHBOARD - Enable web dashboard (default: true)
ENABLE_ADMIN_PANEL - Enable admin panel (default: true)
ENABLE_LOGGING - Enable structured logging (default: true)

Local Testing Setup

For local testing with Ollama running on your machine:

OLLAMA_HOST=localhost
OLLAMA_PORT=11434
OLLAMA_MODEL=llama3:latest
OLLAMA_WORK_MODEL=llama3:latest
OLLAMA_FAMILY_MODEL=llama3:latest
ENVIRONMENT=local

Remote (GPU VM) Setup

For production/testing with remote GPU VM:

OLLAMA_HOST=10.0.30.63
OLLAMA_PORT=11434
OLLAMA_MODEL=llama3.1:8b
OLLAMA_WORK_MODEL=llama3.1:8b
OLLAMA_FAMILY_MODEL=phi3:mini-q4_0
ENVIRONMENT=remote

Using the Toggle Script

The toggle_env.sh script automatically switches between local and remote configurations:

# Switch to remote
./toggle_env.sh

# Switch back to local
./toggle_env.sh

Manual Configuration

You can also edit .env directly:

# Edit the file
nano .env

# Or use environment variables (takes precedence)
export OLLAMA_HOST=localhost
export OLLAMA_MODEL=llama3:latest

Files

.env - Main configuration file (not committed to git)
.env.example - Example template (safe to commit)
toggle_env.sh - Quick toggle script

Notes

Environment variables take precedence over .env file values
The .env file is loaded automatically by config.py and router.py
Make sure python-dotenv is installed: pip install python-dotenv
Restart services after changing .env to load new values
