# TAK Server Hybrid Docker Container

This Docker container combines both the TAK server and PostgreSQL database functionality into a single container. It automatically detects and uses the latest TAK server release from the mounted volume.

## ⚠️ IMPORTANT: TAK Server Files Required

**This container does NOT include TAK server files due to licensing restrictions.** You must provide your own TAK server release files obtained through proper channels:

1. Download TAK server files from the official TAK.gov website
2. Obtain through proper military/government channels
3. Purchase through authorized distributors

**You must have a valid license to use TAK server software.**

## Prerequisites

1. **Valid TAK Server License**: You must have proper licensing/authorization to use TAK server
2. **TAK Server Files**: Download `takserver-docker-X.Y-RELEASE-Z.zip` from official sources
3. **Docker & Docker Compose**: Installed on your system

## Setup Instructions

### Step 1: Obtain TAK Server Files
- Download the TAK server Docker release from official channels
- Place the `takserver-docker-X.Y-RELEASE-Z.zip` file in the `takserver-release/` directory
- The container will automatically detect and use the latest version

### Step 2: File Structure
```

    └── takserver-docker-X.Y-RELEASE-Z.zip  # Your TAK server files
```

## Features

- **Hybrid Architecture**: Combines TAK server and PostgreSQL database in one container
- **Automatic Version Detection**: Finds the latest `takserver-docker-X.Y-RELEASE-Z.zip` file
- **Semantic Versioning**: Uses semantic version sorting to determine the latest release
- **Complete Setup**: Includes PostGIS extension for spatial data support
- **Runtime TAK Setup**: TAK server files are processed at container startup (licensing compliant)
- **User-Provided Files**: No TAK server files included in the image

## Usage

### Option 1: Using Docker Compose (Recommended)

**First, ensure you have TAK server files in the correct directory:**
```bash
# Verify your TAK server files
ls -la takserver-release/
# Should show: takserver-docker-X.Y-RELEASE-Z.zip

# Build and start the hybrid container
docker-compose up -d

# View logs to monitor startup
docker-compose logs -f tak-hybrid

# Stop the container
docker-compose down
```

### Option 2: Using Docker directly

```bash
# Build the image
docker build -t tak-hybrid .

# Run the container (replace /path/to/tak/files with your actual path)
docker run -d \
  --name tak-hybrid \
  -p 5432:5432 \
  -p 8080:8080 \
  -p 8443:8443 \
  -p 8444:8444 \
  -v /path/to/tak/files:/takserver-zip:ro \
  -v tak-data:/opt/tak/data \
  -v tak-logs:/opt/tak/logs \
  tak-hybrid
```

## TAK Server Release Files

Place your TAK server release files in the `takserver-release/` directory. The container will automatically detect and use the latest version based on semantic versioning.

**Supported filename format**: `takserver-docker-X.Y-RELEASE-Z.zip`

Examples:
- `takserver-docker-5.4-RELEASE-19.zip`
- `takserver-docker-5.5-RELEASE-1.zip`
- `takserver-docker-6.0-RELEASE-5.zip`

## Ports

- **5432**: PostgreSQL database
- **8080**: TAK server web interface (HTTP)
- **8443**: TAK server web interface (HTTPS)
- **8444**: TAK server certificate enrollment
- **8446**: TAK server API

## Database Configuration

The container automatically sets up PostgreSQL with:
- Database: `cot`
- User: `martiuser`
- Password: `password`
- PostGIS extension enabled

## Environment Variables

The following environment variables can be customized in the docker-compose.yml:

- `POSTGRES_DB`: Database name (default: cot)
- `POSTGRES_USER`: Database user (default: martiuser)
- `POSTGRES_PASSWORD`: Database password (default: password)

## Helper Scripts

The container includes several helper scripts for management and troubleshooting:

### TAK Version Detection (`/scripts/tak-version.sh`)
```bash
# Find latest TAK release
docker exec tak-hybrid /scripts/tak-version.sh /takserver-zip latest

# List all available releases
docker exec tak-hybrid /scripts/tak-version.sh /takserver-zip list

# Get version from specific file
docker exec tak-hybrid /scripts/tak-version.sh /takserver-zip version /takserver-zip/takserver-docker-5.4-RELEASE-19.zip
```

### Database Setup (`/scripts/db-setup.sh`)
```bash
# Full database setup
docker exec tak-hybrid /scripts/db-setup.sh setup

# Test database connection
docker exec tak-hybrid /scripts/db-setup.sh test

# Print database configuration
docker exec tak-hybrid /scripts/db-setup.sh config
```

### Health Monitoring (`/scripts/healthcheck.sh`)
```bash
# Run all health checks
docker exec tak-hybrid /scripts/healthcheck.sh all

# Check specific components
docker exec tak-hybrid /scripts/healthcheck.sh postgres
docker exec tak-hybrid /scripts/healthcheck.sh database
docker exec tak-hybrid /scripts/healthcheck.sh tak-process
```

## Troubleshooting

### Check container logs
```bash
docker-compose logs tak-hybrid
```

### Access the container shell
```bash
docker-compose exec tak-hybrid /bin/bash
```

### Verify PostgreSQL is running
```bash
docker-compose exec tak-hybrid pg_isready -U martiuser -d cot
```

### Check TAK server status
```bash
docker-compose exec tak-hybrid ps aux | grep tak
```

## Error Handling

The container includes comprehensive error checking:

### Missing TAK Server Files
```
ERROR: No TAK server files found!
Please mount a directory containing takserver-docker-X.Y-RELEASE-Z.zip files to /takserver-zip
```
**Solution**: Ensure you have properly mounted the directory containing your TAK server files.

### Invalid File Format
```
ERROR: No takserver-docker-X.Y-RELEASE-Z.zip file found in /takserver-zip/
Please ensure you have a file matching the pattern: takserver-docker-X.Y-RELEASE-Z.zip
```
**Solution**: Verify your TAK server file follows the correct naming convention.

### Licensing Compliance

This container design ensures license compliance by:
- **Not redistributing TAK server files**
- **Requiring users to provide their own licensed files**
- **Processing files only at runtime**
- **Clear documentation of licensing requirements**
