 # Changelog

+## 2025-11-18 - 2.0.0 - BREAKING CHANGE(DockerHost)
+Rename DockerHost constructor option 'dockerSockPath' to 'socketPath' and update internal socket path handling
+
+- Breaking: constructor option renamed from 'dockerSockPath' to 'socketPath' — callers must update their code.
+- Constructor now reads the provided 'socketPath' option first, then falls back to DOCKER_HOST, CI, and finally the default unix socket.
+- README examples and documentation updated to use 'socketPath'.
+
 ## 2025-11-17 - 1.3.6 - fix(streaming)
 Convert smartrequest v5 web ReadableStreams to Node.js streams and update deps for streaming compatibility

+## 🔌 Socket Path Configuration
+
+The library determines which Docker socket to use in the following priority order:
+
+1. **Constructor option** - `socketPath` parameter (highest priority)
+2. **Environment variable** - `DOCKER_HOST` environment variable
+3. **CI environment** - If `CI` env var is set, uses `http://docker:2375/`
+4. **Default** - Falls back to `http://unix:/var/run/docker.sock:`

+### CI/CD Pipeline Integration
+
+```typescript
+// In your CI/CD pipeline
+const docker = new DockerHost({
+  socketPath: process.env.DOCKER_HOST || '/var/run/docker.sock',
+});
+
+await docker.start();
+
+// Build and push process
+const image = await DockerImage.createFromTarStream(docker, {
+  tarStream: buildArtifactStream,
+  creationObject: {
+    imageUrl: 'my-app',
+    imageTag: process.env.CI_COMMIT_SHA,
+  },
+});
+
+await DockerImage.tagImageByIdOrName(docker, `my-app:${process.env.CI_COMMIT_SHA}`, {
+  registry: 'registry.company.com',
+  imageName: 'production/my-app',
+  imageTag: 'latest',
+});
+
+// Push to registry (authentication required)
+// Note: Pushing requires proper registry authentication
+```
+
+### Dynamic Service Scaling
+
+```typescript
+// Monitor and scale services based on load
+const services = await docker.getServices();
+const webService = services.find(s => s.Spec.Name === 'web-app');
+
+if (webService && webService.Spec.Mode.Replicated) {
+  const currentReplicas = webService.Spec.Mode.Replicated.Replicas;
+  console.log(`Current replicas: ${currentReplicas}`);
+
+  // Scale based on your metrics
+  // (Scaling API would need to be implemented)
+}
+```

+## 🔑 Key Concepts
+
+- **DockerHost**: Main entry point for Docker API communication
+- **Socket Path Priority**: Constructor option → `DOCKER_HOST` env → CI mode → default socket
+- **Swarm Mode Required**: Services and secrets require Docker Swarm to be activated
+- **Type Safety**: Full TypeScript support with comprehensive interfaces
+- **Streaming Support**: Real-time event monitoring and tar stream operations
+- **S3 Integration**: Built-in image storage/retrieval from S3-compatible storage
