Understanding the Fabric Operator

Basic Concepts

The Hyperledger Fabric Operator is a Kubernetes operator designed to automate the deployment and management of Hyperledger Fabric networks. It follows the Kubernetes operator pattern, extending the platform's capabilities to handle Fabric-specific resources and operations.

"The Fabric Operator represents a bridge between traditional blockchain network management and modern cloud-native practices, enabling organizations to leverage Kubernetes' power for blockchain infrastructure."

Role in Enterprise Blockchain

The operator plays a crucial role in:

• Automating network deployment
• Managing network components
• Handling configuration updates
• Ensuring high availability
• Monitoring network health

Core Components

Monitoring and Metrics

The new release introduces the hlf_operator_current_time_seconds Prometheus gauge metric, which:

• Exposes current time in Unix Epoch seconds
• Enables precise monitoring of operator timing
• Facilitates time-based alerting and monitoring

For a complete list of all supported metrics, see the Prometheus Metrics Documentation.
