Component C56 – SyncMaster
By Raj Marni. March 26, 2025. Revised. Version: 0.0.01
1. Overview
C56 – SyncMaster is a critical component in the k8or Orbit ecosystem, designed to ensure the real-time synchronization of data, configurations, and state across a distributed k3s clusters. By handling data consistency and event propagation, SyncMaster integrates with multiple key components like C8 (Portal), C20 (Chart Store), and C24 (Helm Chart Artifact), providing a seamless and cohesive environment. Its event-driven approach enables efficient and reliable communication, ensuring that configurations are up-to-date across multiple environments and clusters.
2. Key Functions
Data Synchronization Across Components
Coordinated Updates: SyncMaster ensures that any configuration, data, or state changes in one part of the system are propagated and synchronized to relevant components.
State Consistency: It manages consistency in distributed systems, ensuring that multiple components operate on the same version of the data or configuration at any given time.
Event Propagation and Notification
Event Distribution: SyncMaster listens for changes in C8, C20 of the system and propagates those changes to C96 and C100 components that need to be informed of updates.
Notifications: Sends notifications about the status of various components or changes in data to ensure that other parts of the system react appropriately (e.g., triggering a new deployment, scaling operations).
Integration Across Services
Service Coordination: SyncMaster acts as an integration layer between different services that need to stay in sync across multiple regions or clusters.
Multi-Cluster Sync: Ensures that data or configurations are mirrored across geographically distributed clusters, enabling high availability and fault tolerance.
Centralized Configuration Management
Configuration Sync: Handles updates to system configurations and ensures they are correctly applied across various components (like C20 (Chart Store) and C28 (Kustomize)).
Unified Configuration Store: Works alongside other components to update and distribute configuration settings, ensuring consistent environment settings across dev, test, and production stages.
3. Interactions with Other Components
C8 – K8or Portal
Purpose: SyncMaster interacts with the K8or Portal (C8) to receive updates from users (e.g., image uploads, metadata changes) and propagate these changes across the system.
Mechanism: SyncMaster ensures that changes made in the portal (via user inputs) are reflected in the relevant components in real-time.
C4 – Docker Image Build Process
Purpose: SyncMaster coordinates the sync of newly built Docker images or updated image versions across relevant components, ensuring that updated images are properly reflected in configuration and deployment environments.
Mechanism: When a new Docker image is built and stored (via C4), SyncMaster triggers the synchronization to ensure that C8 (Portal) and C12 (Manifestor) get updated metadata and images.
C20 – Chart Store
Purpose: SyncMaster works with the Chart Store (C20) to ensure that Helm charts, once generated by C24, are synchronized across environments.
Mechanism: When new Helm charts are stored or updated in C20, SyncMaster ensures they are distributed or made available to relevant services (like C28 (Kustomize) for further customization).
C56C100-1 & C56C96-1 (Component Interactions)
Purpose: SyncMaster integrates with subcomponents to provide data synchronization and event propagation at the local component level.
Mechanism: SyncMaster communicates with specific subcomponents within C56 (like C56C100-1 or C56C96-1) to enable data consistency and updates across microservices or clusters.
4. Technology & Protocols
Event-Driven Architecture:
Uses event-based mechanisms (message queues) to propagate changes across components.
Real-time event notifications allow low-latency communication and system responsiveness.
RESTful APIs:
Uses standard protocols like RESTto communicate with other components in the k8or Orbit ecosystem, ensuring reliable data transmission and synchronization.
Database or State Store Syncing:
SyncMaster relies on a distributed state storeto ensure that data across components (like configuration data) is consistent and up-to-date.
Multi-Cluster Data Replication:
For environments with multiple Kubernetes clusters across regions, SyncMaster helps maintain data consistency through cross-cluster replication mechanisms.
5. Benefits & Impact
Reduced Configuration Drift
By synchronizing data and configurations in real-time, SyncMaster ensures consistency across all components, preventing drift that can lead to deployment failures or system inconsistencies.
Enhanced Reliability and Availability
Multi-cluster synchronization ensures that even if one cluster goes down, another can take over seamlessly, maintaining availability and business continuity.
Streamlined Workflow Automation
SyncMaster automates the propagation of changes across the system, enabling a smooth and automated workflow for updates and configuration changes.
Centralized Control
Provides a single point of control for managing and synchronizing data, reducing the complexity of managing distributed systems manually.
Improved System Performance
Through event-driven synchronization and optimized data flow, SyncMaster helps maintain efficient communication between components, reducing unnecessary load and latency.
