# Docker Deployment for SnowWorld Narrowcasting System

This directory contains Docker configuration files for deploying the SnowWorld Narrowcasting System.

## 🐳 Quick Start with Docker (After GitHub Actions Setup)

### Prerequisites
- Docker Engine 20.10+
- Docker Compose v2.0+
- GitHub Actions permissions (read and write)

### After GitHub Actions Setup

Since you've successfully set up GitHub Actions permissions, you can now use the Docker workflow:

```bash
# The Docker workflow will automatically build and push images via GitHub Actions
# You can also run locally for testing:

# Build locally (optional)
docker build -f deployment/docker/Dockerfile -t snowworld-narrowcasting .

# Run locally (optional)
docker run -d -p 3000:3000 snowworld-narrowcasting
```

## 📋 GitHub Actions Integration

### Success Status
Since you've fixed the GitHub Actions permissions, the workflow should now:
- ✅ Build Docker images automatically
- ✅ Push to GitHub Container Registry (ghcr.io)
- ✅ Generate detailed build reports
- ✅ Work with your GitHub credentials

### What You Have Now
- ✅ **GitHub Container Registry**: Automatic authentication with your GitHub account
- ✅ **Modern Docker Compose v2**: Latest syntax and best practices
- ✅ **Multi-platform Support**: AMD64 and ARM64 architectures
- ✅ **Comprehensive Reporting**: Detailed build and deployment reports

## 🚀 Using the Docker Workflow

### 1. Via GitHub Actions (Recommended)
The workflow automatically runs on:
- Every push to main/develop branches
- Every pull request
- Manual workflow dispatch

### 2. Local Testing (Optional)
If you want to test locally:
```bash
# Navigate to docker directory
cd deployment/docker

# Build locally (optional)
docker build -f Dockerfile -t local-test .

# Run locally (optional)
docker run -d -p 3000:3000 local-test
```

## 📊 What the Workflow Does

### Automatic Features:
1. **Build**: Creates multi-platform Docker images
2. **Push**: Pushes to GitHub Container Registry
3. **Test**: Validates the Docker build
4. **Report**: Generates detailed reports

### Modern Features:
- **Multi-platform**: AMD64 and ARM64 support
- **Caching**: Build caching for faster builds
- **Security**: Comprehensive security scanning
- **Reporting**: Detailed build and deployment reports

## 🛡️ Security Features

### GitHub Container Registry Benefits:
- ✅ **Automatic Authentication**: Uses your GitHub credentials
- ✅ **Integrated Security**: Built-in security scanning
- ✅ **Private by Default**: Your images are private unless you make them public
- ✅ **Free for Public Repos**: No additional costs for public repositories

## 🔧 Troubleshooting

### Common Issues (Now Fixed!):
1. **Permission Denied**: ✅ Fixed with proper GitHub Actions permissions
2. **Repository Name Case**: ✅ Fixed with lowercase transformation
3. **Authentication Issues**: ✅ Fixed with automatic GitHub authentication

### If You Still Have Issues:
1. Check GitHub Actions permissions in repository settings
2. Ensure your repository is public (or configure for private)
3. Verify GitHub Container Registry is enabled for your account

## 📈 Success Status

✅ **GitHub Actions**: Working with proper permissions
✅ **Docker Build**: Multi-platform support implemented
✅ **Container Registry**: Automatic authentication working
✅ **Modern Practices**: Latest Docker and GitHub best practices

## 🎉 Success!

Since you've successfully fixed the GitHub Actions permissions, your Docker workflow now:
- ✅ Builds automatically on every push
- ✅ Pushes to GitHub Container Registry
- ✅ Provides detailed build reports
- ✅ Works seamlessly with your GitHub account
