 # Changelog
 
+## 2025-11-24 - 3.0.0 - BREAKING CHANGE(DockerHost)
+Refactor public API to DockerHost facade; introduce DockerResource base; make resource static methods internal; support flexible descriptors and stream compatibility
+
+- Refactored architecture: DockerHost is now the single public entry point (Facade) for all operations; direct static calls like DockerImage.createFromRegistry(...) are now internal and replaced by DockerHost.createImageFromRegistry(...) and similar factory methods.
+- Introduced DockerResource abstract base class used by all resource classes (DockerContainer, DockerImage, DockerNetwork, DockerSecret, DockerService) with a required refresh() method and standardized dockerHost property.
+- Static methods on resource classes were renamed / scoped as internal (prefixed with _): _list, _fromName/_fromId, _create, _createFromRegistry, _createFromTarStream, _build, etc. Consumers should call DockerHost methods instead.
+- Creation descriptor interfaces (container, service, etc.) now accept either string identifiers or resource instances (e.g. image: string | DockerImage, networks: (string | DockerNetwork)[], secrets: (string | DockerSecret)[]). DockerHost resolves instances internally.
+- DockerImageStore imageStore has been made private on DockerHost; new public methods DockerHost.storeImage(name, stream) and DockerHost.retrieveImage(name) provide access to the image store.
+- Streaming compatibility: updated requestStreaming to convert web ReadableStreams (smartrequest v5+) to Node.js streams via smartstream.nodewebhelpers, preserving backward compatibility for existing streaming APIs (container logs, attach, exec, image import/export, events).
+- Container enhancements: added full lifecycle and streaming/interactive APIs on DockerContainer: refresh(), inspect(), start(), stop(), remove(), logs(), stats(), streamLogs(), attach(), exec().
+- Service creation updated: resolves image/network/secret descriptors (strings or instances); adds labels.version from image; improved resource handling and port/secret/network resolution.
+- Network and Secret classes updated to extend DockerResource and to expose refresh(), remove() and lookup methods via DockerHost (createNetwork/getNetworks/getNetworkByName, createSecret/getSecrets/getSecretByName/getSecretById).
+- Tests and docs updated: migration guide and examples added (readme.hints.md, README); test timeout reduced from 600s to 300s in package.json.
+- BREAKING: Public API changes require consumers to migrate away from direct resource static calls and direct imageStore access to the new DockerHost-based factory methods and storeImage/retrieveImage APIs.
+
+## 2025-11-18 - 2.1.0 - feat(DockerHost)
+Add DockerHost.ping() to check Docker daemon availability and document health-check usage
+
+- Add DockerHost.ping() method that issues a GET to /_ping and throws an error if the response status is not 200
+- Update README: show ping() in Quick Start, add health check examples (isDockerHealthy, waitForDocker) and mention Health Checks in Key Concepts
+
+## 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

 # Docker Module - Development Hints
 
+## OOP Refactoring - Clean Architecture (2025-11-24)
+
+### Architecture Changes
+The module has been restructured to follow a clean OOP Facade pattern:
+- **DockerHost** is now the single entry point for all Docker operations
+- All resource classes extend abstract `DockerResource` base class
+- Static methods are prefixed with `_` to indicate internal use
+- Public API is exclusively through DockerHost methods
+
+### Key Changes
+
+**1. Factory Pattern**
+- All resource creation/retrieval goes through DockerHost:
+  ```typescript
+  // Old (deprecated):
+  const container = await DockerContainer.getContainers(dockerHost);
+  const network = await DockerNetwork.createNetwork(dockerHost, descriptor);
+
+  // New (clean API):
+  const containers = await dockerHost.getContainers();
+  const network = await dockerHost.createNetwork(descriptor);
+  ```
+
+**2. Container Management Methods Added**
+The DockerContainer class now has full CRUD and streaming operations:
+
+**Lifecycle:**
+- `container.start()` - Start container
+- `container.stop(options?)` - Stop container
+- `container.remove(options?)` - Remove container
+- `container.refresh()` - Reload state
+
+**Information:**
+- `container.inspect()` - Get detailed info
+- `container.logs(options)` - Get logs as string (one-shot)
+- `container.stats(options)` - Get stats
+
+**Streaming & Interactive:**
+- `container.streamLogs(options)` - Stream logs continuously (follow mode)
+- `container.attach(options)` - Attach to main process (PID 1) with bidirectional stream
+- `container.exec(command, options)` - Execute commands in container interactively
+
+**Example - Stream Logs:**
+```typescript
+const container = await dockerHost.getContainerById('abc123');
+const logStream = await container.streamLogs({ timestamps: true });
+
+logStream.on('data', (chunk) => {
+  console.log(chunk.toString());
+});
+```
+
+**Example - Attach to Container:**
+```typescript
+const { stream, close } = await container.attach({
+  stdin: true,
+  stdout: true,
+  stderr: true
+});
+
+// Pipe to/from process
+process.stdin.pipe(stream);
+stream.pipe(process.stdout);
+
+// Later: detach
+await close();
+```
+
+**Example - Execute Command:**
+```typescript
+const { stream, close } = await container.exec('ls -la /app', {
+  tty: true
+});
+
+stream.on('data', (chunk) => {
+  console.log(chunk.toString());
+});
+
+stream.on('end', async () => {
+  await close();
+});
+```
+
+**3. DockerResource Base Class**
+All resource classes now extend `DockerResource`:
+- Consistent `dockerHost` property (not `dockerHostRef`)
+- Required `refresh()` method
+- Standardized constructor pattern
+
+**4. ImageStore Encapsulation**
+- `dockerHost.imageStore` is now private
+- Use `dockerHost.storeImage(name, stream)` instead
+- Use `dockerHost.retrieveImage(name)` instead
+
+**5. Creation Descriptors Support Both Primitives and Instances**
+Interfaces now accept both strings and class instances:
+```typescript
+// Both work:
+await dockerHost.createService({
+  image: 'nginx:latest',  // String
+  networks: ['my-network'],  // String array
+  secrets: ['my-secret']  // String array
+});
+
+await dockerHost.createService({
+  image: imageInstance,  // DockerImage instance
+  networks: [networkInstance],  // DockerNetwork array
+  secrets: [secretInstance]  // DockerSecret array
+});
+```
+
+### Migration Guide
+Replace all static method calls with dockerHost methods:
+- `DockerContainer.getContainers(host)` → `dockerHost.getContainers()`
+- `DockerImage.createFromRegistry(host, opts)` → `dockerHost.createImageFromRegistry(opts)`
+- `DockerService.createService(host, desc)` → `dockerHost.createService(desc)`
+- `dockerHost.imageStore.storeImage(...)` → `dockerHost.storeImage(...)`
+
