## 📚 Complete API Guide

### 🐳 DockerHost - Your Gateway to Docker

The `DockerHost` class is your primary interface to interact with the Docker daemon.

```typescript
import { DockerHost } from '@apiclient.xyz/docker';

// Initialize with default local socket
const docker = new DockerHost();

// Custom initialization options
const customDocker = new DockerHost({
  socketPath: '/var/run/docker.sock',  // Unix socket path
  // or
  socketPath: 'tcp://192.168.1.100:2375'  // TCP connection
});

// Start and stop (for lifecycle management)
await docker.start();
// ... do your work
await docker.stop();
```

### 📦 Container Management

#### List All Containers

```typescript
// Get all containers (including stopped ones)
const allContainers = await docker.getContainers();

// Each container includes detailed information
allContainers.forEach(container => {
  console.log(`Container: ${container.Names[0]}`);
  console.log(`  ID: ${container.Id}`);
  console.log(`  Status: ${container.Status}`);
  console.log(`  Image: ${container.Image}`);
  console.log(`  State: ${container.State}`);
});
```

#### Create and Manage Containers

```typescript
import { DockerContainer } from '@apiclient.xyz/docker';

// Create a container with detailed configuration
const container = await DockerContainer.create(docker, {
  Image: 'nginx:latest',
  name: 'my-nginx-server',
  HostConfig: {
    PortBindings: {
      '80/tcp': [{ HostPort: '8080' }]
    },
    RestartPolicy: {
      Name: 'unless-stopped'
    },
    Memory: 512 * 1024 * 1024, // 512MB memory limit
  },
  Env: [
    'NODE_ENV=production',
    'LOG_LEVEL=info'
  ],
  Labels: {
    'app': 'web-server',
    'environment': 'production'
  }
});

console.log(`Container created: ${container.Id}`);

// Container operations (these would need to be implemented)
// await container.start();
// await container.stop();
// await container.remove();
```

#### Get Container by ID

```typescript
const container = await DockerContainer.getContainerById(docker, 'container-id-here');
if (container) {
  console.log(`Found container: ${container.Names[0]}`);
}
```

### 🖼️ Image Management

#### Pull Images from Registry

```typescript
import { DockerImage } from '@apiclient.xyz/docker';

// Pull an image from Docker Hub
const image = await DockerImage.createFromRegistry(docker, {
  imageName: 'node',
  imageTag: '18-alpine',
  // Optional: provide registry authentication
  authToken: 'your-registry-auth-token'
});

console.log(`Image pulled: ${image.RepoTags[0]}`);
console.log(`Size: ${(image.Size / 1024 / 1024).toFixed(2)} MB`);
```

#### Import Images from Tar

```typescript
import * as fs from 'fs';

// Import from a tar stream
const tarStream = fs.createReadStream('./my-image.tar');
const importedImage = await DockerImage.createFromTarStream(docker, {
  tarStream,
  imageUrl: 'file://./my-image.tar',
  imageTag: 'my-app:v1.0.0'
});
```

#### Export Images to Tar

```typescript
// Export an image to a tar stream
const image = await DockerImage.getImageByName(docker, 'nginx:latest');
const exportStream = await image.exportToTarStream();

// Save to file
const writeStream = fs.createWriteStream('./nginx-export.tar');
exportStream.pipe(writeStream);
```

#### Tag Images

```typescript
// Tag an existing image
await DockerImage.tagImageByIdOrName(docker, 'node:18-alpine', {
  registry: 'myregistry.com',
  imageName: 'my-node-app',
  imageTag: 'v2.0.0'
});
// Result: myregistry.com/my-node-app:v2.0.0
```

### 🌐 Network Management

#### Create Custom Networks

```typescript
import { DockerNetwork } from '@apiclient.xyz/docker';

// Create a bridge network
const network = await DockerNetwork.createNetwork(docker, {
  Name: 'my-app-network',
  Driver: 'bridge',
  EnableIPv6: false,
  IPAM: {
    Driver: 'default',
    Config: [{
      Subnet: '172.28.0.0/16',
      Gateway: '172.28.0.1'
    }]
  },
  Labels: {
    'project': 'my-app',
    'environment': 'production'
  }
});

console.log(`Network created: ${network.Id}`);
```

#### List and Inspect Networks

```typescript
// Get all networks
const networks = await docker.getNetworks();
networks.forEach(net => {
  console.log(`Network: ${net.Name} (${net.Driver})`);
  console.log(`  Scope: ${net.Scope}`);
  console.log(`  Internal: ${net.Internal}`);
});

// Get specific network
const appNetwork = await DockerNetwork.getNetworkByName(docker, 'my-app-network');

// Get containers on network
const containers = await appNetwork.getContainersOnNetwork();
console.log(`Containers on network: ${containers.length}`);
```

### 🎭 Service Management (Swarm Mode)

#### Deploy Services

```typescript
import { DockerService } from '@apiclient.xyz/docker';

// Create a replicated service
const service = await DockerService.createService(docker, {
  name: 'web-api',
  image: 'my-api:latest',
  replicas: 3,
  ports: [{
    Protocol: 'tcp',
    PublishedPort: 80,
    TargetPort: 3000
  }],
  networks: ['my-app-network'],
  labels: {
    'app': 'api',
    'version': '2.0.0'
  },
  resources: {
    limits: {
      Memory: 256 * 1024 * 1024, // 256MB
      CPUs: 0.5
    }
  },
  secrets: ['api-key', 'db-password'],
  mounts: [{
    Target: '/data',
    Source: 'app-data',
    Type: 'volume'
  }]
});

console.log(`Service deployed: ${service.ID}`);
```

#### Manage Services

```typescript
// List all services
const services = await docker.getServices();
services.forEach(service => {
  console.log(`Service: ${service.Spec.Name}`);
  console.log(`  Replicas: ${service.Spec.Mode.Replicated.Replicas}`);
  console.log(`  Image: ${service.Spec.TaskTemplate.ContainerSpec.Image}`);
});

// Get service by name
const myService = await DockerService.getServiceByName(docker, 'web-api');

// Check if service needs update
const needsUpdate = await myService.needsUpdate();
if (needsUpdate) {
  console.log('Service configuration has changed, update needed');
}

// Remove service
await myService.remove();
```

### 🔐 Secrets Management

```typescript
import { DockerSecret } from '@apiclient.xyz/docker';

// Create a secret
const secret = await DockerSecret.createSecret(docker, {
  name: 'api-key',
  data: Buffer.from('super-secret-key-123').toString('base64'),
  labels: {
    'app': 'my-app',
    'type': 'api-key'
  }
});

console.log(`Secret created: ${secret.ID}`);

// List secrets
const secrets = await DockerSecret.getSecrets(docker);
secrets.forEach(secret => {
  console.log(`Secret: ${secret.Spec.Name}`);
});

// Get secret by name
const apiKeySecret = await DockerSecret.getSecretByName(docker, 'api-key');

// Update secret
await apiKeySecret.update({
  data: Buffer.from('new-secret-key-456').toString('base64')
});

// Remove secret
await apiKeySecret.remove();
```

### 💾 S3 Image Storage

Store and retrieve Docker images from S3-compatible storage:

```typescript
// Configure S3 storage
await docker.addS3Storage({
  endpoint: 's3.amazonaws.com',
  accessKeyId: 'your-access-key',
  secretAccessKey: 'your-secret-key',
  bucket: 'docker-images'
});

// Store an image to S3
const imageStore = docker.imageStore;
await imageStore.storeImage('my-app:v1.0.0');

// Retrieve an image from S3
const retrievedImage = await imageStore.getImage('my-app:v1.0.0');
```

### 📊 Event Monitoring

Monitor Docker events in real-time using RxJS observables:

```typescript
// Subscribe to Docker events
const eventStream = docker.getEventObservable();

const subscription = eventStream.subscribe({
  next: (event) => {
    console.log(`Event: ${event.Type} - ${event.Action}`);
    console.log(`Actor: ${event.Actor.ID}`);
    console.log(`Time: ${new Date(event.time * 1000).toISOString()}`);
  },
  error: (err) => console.error('Event stream error:', err),
  complete: () => console.log('Event stream completed')
});

// Unsubscribe when done
subscription.unsubscribe();
```

### 🔧 Registry Authentication

Authenticate with Docker registries for private images:

```typescript
// Authenticate with Docker Hub
await docker.auth({
  username: 'your-username',
  password: 'your-password',
  serveraddress: 'https://index.docker.io/v1/'
});

// Or use existing Docker config
const authToken = await docker.getAuthTokenFromDockerConfig('myregistry.com');

// Use auth token when pulling images
const privateImage = await DockerImage.createFromRegistry(docker, {
  imageName: 'myregistry.com/private/image',
  imageTag: 'latest',
  authToken
});
```

### 🔄 Swarm Mode

Initialize and manage Docker Swarm:

```typescript
// Initialize swarm mode
await docker.activateSwarm({
  ListenAddr: '0.0.0.0:2377',
  AdvertiseAddr: '192.168.1.100:2377',
  ForceNewCluster: false
});

// Now you can create services, secrets, and use swarm features
const service = await DockerService.createService(docker, {
  name: 'my-swarm-service',
  image: 'nginx:latest',
  replicas: 5
  // ... more service config
});
```

## 🏗️ Advanced Examples

### Complete Application Stack

```typescript
async function deployStack() {
  const docker = new DockerHost();
  
  // Create network
  const network = await DockerNetwork.createNetwork(docker, {
    Name: 'app-network',
    Driver: 'overlay' // for swarm mode
  });
  
  // Create secrets
  const dbPassword = await DockerSecret.createSecret(docker, {
    name: 'db-password',
    data: Buffer.from('strong-password').toString('base64')
  });
  
  // Deploy database service
  const dbService = await DockerService.createService(docker, {
    name: 'postgres',
    image: 'postgres:14',
    networks: ['app-network'],
    secrets: ['db-password'],
    env: ['POSTGRES_PASSWORD_FILE=/run/secrets/db-password']
  });
  
  // Deploy application service
  const appService = await DockerService.createService(docker, {
    name: 'web-app',
    image: 'my-app:latest',
    replicas: 3,
    networks: ['app-network'],
    ports: [{ Protocol: 'tcp', PublishedPort: 80, TargetPort: 3000 }]
  });
  
  console.log('Stack deployed successfully!');
