## 🚀 Quick Start

### Prerequisites

- Docker & Docker Compose
- Python 3.12+ (for local development)
- uv (recommended) or pip

### LLM configuration

GigaEvo platform reads all LLM settings from a single repo-level file: `llm_models.yml`. Create `llm_models.yml` from the `llm_models.yml.example` template and fill in your credentials.

### Using the Deployment System

GigaEvo Platform uses the **deploy.sh** script with Docker Compose for service orchestration:

#### 1. Deploy Everything (Recommended)

```bash
make deploy
# Or directly:
./deploy.sh deploy
```

This will deploy with automated health checks:

- **Infrastructure**: PostgreSQL, Kafka (KRaft), Redis (2 instances), MinIO
- **Applications**: Master API, Runner API, WebUI
- **Networking**: Docker network and shared volumes
- **Health Monitoring**: Automatic service health verification

#### 2. Deploy Development Environment

```bash
make dev
```

#### 3. Individual Service Development

```bash
# Run services locally for development (requires infrastructure running)
make master-api    # Master API on port 8000
make runner-api    # Runner API on port 8001
make web-ui        # WebUI on port 7860
```

#### 4. Service Management

```bash
# Check all services status
make status
# Or:
./deploy.sh status

# Stop all services
make stop
# Or:
./deploy.sh stop

# Remove deploy containers and volumes
./deploy.sh clean

# Full cleanup for both dev and deploy
make clean

# Restart specific service
make restart SERVICE=master-api
make restart SERVICE=runner-api
make restart SERVICE=web-ui
make restart SERVICE=kafka

# View service logs
./deploy.sh logs [service-name]
```

### Access Points

- **WebUI**: `http://localhost:${WEB_UI_HOST_PORT}` (default `7860`)
- **Master API**: `http://localhost:${MASTER_API_HOST_PORT}` (default `8000`)
- **Runner API**: `http://localhost:${RUNNER_API_HOST_PORT}` (default `8001`)
- **MinIO Console**: `http://localhost:${MINIO_CONSOLE_HOST_PORT}` (default `9001`; credentials come from `MINIO_ROOT_USER` / `MINIO_ROOT_PASSWORD`)
- **Kafka Broker**: `localhost:${KAFKA_HOST_PORT}` (default `9092`)
- **Kafka UI**: available in dev mode at `http://localhost:${KAFKA_UI_HOST_PORT}` (default `8080`)

### Runner pool size configuration

By default, the platform starts with a single runner instance. To run multiple experiments in parallel, increase the runner pool size:

```bash
# In .env file (or export before running `make deploy`)
RUNNER_POOL_SIZE=3    # Number of runner instances (default: 1)
```

The system automatically generates a `docker-compose.runner-pool.*.generated.yml` file with N runner services.
All generated runner services reuse one shared runner image tagged from `COMPOSE_PROJECT_NAME`.

### Environment configuration

The main deployment-related environment variables for this repo are:

- `COMPOSE_PROJECT_NAME` for Compose resource naming and the shared runner image tag
- `GIGAEVO_NETWORK_NAME` for the shared Docker network used by the deploy stack
- `GIGAEVO_CORE_REPO_URL` / `GIGAEVO_CORE_REF` for the baked `gigaevo-core` runner image inputs
- `MEMORY_API_URL` for the external `gigaevo-memory` API endpoint as seen from runner containers
- `MINIO_ROOT_USER` and `MINIO_ROOT_PASSWORD` for MinIO server and platform storage access
- `*_HOST_PORT` values for published service ports

`COMPOSE_PROJECT_NAME` is required for supported container flows.

Example:

```bash
COMPOSE_PROJECT_NAME=gigaevo-platform
GIGAEVO_NETWORK_NAME=gigaevo-platform-network
MINIO_ROOT_USER=gigaevoadmin
MINIO_ROOT_PASSWORD=change-this-minio-password
POSTGRES_HOST_PORT=5432
REDIS_HOST_PORT=6379
REDIS_GIGAVOLVE_HOST_PORT=6380
KAFKA_HOST_PORT=9092
KAFKA_DOCKER_HOST_PORT=29092
MASTER_API_HOST_PORT=8000
RUNNER_API_HOST_PORT=8001
WEB_UI_HOST_PORT=7860
MINIO_API_HOST_PORT=9000
MINIO_CONSOLE_HOST_PORT=9001
KAFKA_UI_HOST_PORT=8080
GIGAEVO_CORE_REPO_URL=https://github.com/FusionBrainLab/gigaevo-core
GIGAEVO_CORE_REF=main
MEMORY_API_URL=http://host.docker.internal:8002
```

`MEMORY_API_URL` must be reachable from runner containers. For local development, `http://host.docker.internal:8002` is the recommended default for an externally started `gigaevo-memory` API.

### Runner pool instance controls (WebUI)

The WebUI “Runner Instances” tab calls the Master API (`/api/v1/instances/*`) to start/stop/restart runners and fetch container logs.

With a **Compose-managed runner pool** (`RUNNER__MANAGE_CONTAINERS=false`, the default in `make dev`/`make deploy`), Master controls the already-created `runner-api-N` containers via Docker.

Requirements:

- `master-api` has Docker CLI access via the host socket: mount `/var/run/docker.sock` (and ensure the container user can read/write it; otherwise run `master-api` as root or align the socket group).
- Runner containers are started by Docker Compose (Master finds them via `com.docker.compose.service=runner-api-N` labels; keep `COMPOSE_PROJECT_NAME` and `GIGAEVO_NETWORK_NAME` aligned with this deployment).

Security note: mounting the Docker socket grants the `master-api` container root-equivalent control over the host Docker engine.

Quick manual checks (requires the stack running):

```bash
bash ./smoke_runner_instances.sh status
bash ./smoke_runner_instances.sh health
bash ./smoke_runner_instances.sh logs runner-1 100
```

## 📚 API Endpoints

- `experiment-started` - Experiment execution started
- `experiment-stopped` - Experiment execution stopped
- `runner-status` - Runner status updates

## 🛠️ Development

### Local Development Setup

```bash
# Verify required local tools (docker, docker compose, python3)
make check-tools

# Install all dependencies
make install

# Run services individually (infrastructure must be running first)
make master-api    # Master API on port 8000
make runner-api    # Runner API on port 8001
make web-ui        # WebUI on port 7860
```

### Container-Based Development

```bash
# Development with hot reload (foreground)
make dev

# Stop containers
make stop

# Stop foreground session
# Ctrl+C

# Full cleanup (including volumes)
make clean-dev
```

### Code Quality

```bash
make check-runner-compose   # Validate the pool resolves one shared runner image
make lint     # Run linting with ruff
make format   # Format code with ruff
make test     # Run tests (individual components)
```

### Database Management

```bash
make db-reset     # Drop and recreate database
make db-migrate   # Run database migrations
```

## 🐛 Troubleshooting

### Common Issues

1. **Port Conflicts**: Ensure these ports are free:

- 5432: PostgreSQL
   - 6379, 6380: Redis (2 instances)
   - 7860: WebUI
   - 8000: Master API
   - 8001: Runner API
   - 9000, 9001: MinIO
   - 9092, 29092: Kafka

2. **Deployment Issues**:

```bash
   # Check deployment status
   ./deploy.sh status
   # Or:
   make status

# View service logs
   ./deploy.sh logs [service-name]
   # Or for all services:
   ./deploy.sh logs

# Restart specific service
   make restart SERVICE=master-api
   make restart SERVICE=runner-api
   make restart SERVICE=web-ui
   make restart SERVICE=kafka
   ```

3. **Service Health Check Failures**:

```bash
   # The deploy script automatically checks service health
   # If services fail to start, check logs:
   ./deploy.sh logs postgres
   ./deploy.sh logs kafka
   ./deploy.sh logs master-api
   ```

4. **Database Connection Issues**:

```bash
   # Reset database (use after schema changes)
   make db-reset

# Check PostgreSQL logs
   ./deploy.sh logs postgres
   ```

### Environment Variables

Key environment variables for Master API:

- `DATABASE__URL` - PostgreSQL connection string
- `KAFKA__BOOTSTRAP_SERVERS` - Kafka bootstrap servers
- `REDIS_URL` - Redis connection URL
- `STORAGE__ENDPOINT_URL` - MinIO endpoint
- `STORAGE__ACCESS_KEY` - MinIO access key
- `STORAGE__SECRET_KEY` - MinIO secret key

In the provided Compose setup, `STORAGE__ACCESS_KEY` and `STORAGE__SECRET_KEY` are populated from `MINIO_ROOT_USER` and `MINIO_ROOT_PASSWORD`.

## 📊 Architecture Details

### Current Kafka-Based Architecture

The platform uses a modern microservices architecture with:

1. **Kafka Message Broker** - Asynchronous service communication with topics for experiment coordination
2. **Separate Docker Compositions** - Modular deployment with infrastructure and application services
3. **Health Monitoring** - Automated service health checks and recovery
4. **Resource Isolation** - Dedicated Redis instances and MinIO storage
5. **uv Dependency Management** - Fast package installation and dependency caching

### Service Orchestration

- **deploy.sh**: Main deployment script with health checks and service management
- **docker-compose.kafka.yml**: Core infrastructure services
- **docker-compose.\*.yml**: Individual application service configurations
- **Makefile**: Development commands and shortcuts
