Welcome to your go-to guide for mastering Hyperledger Cello, an innovative blockchain provisioning and operation system that streamlines the management of blockchain networks.

Introduction

With Hyperledger Cello, you have the power to:

• Quickly create a Blockchain as a Service (BaaS) platform from scratch.
• Effortlessly provision customizable Blockchains, such as a Hyperledger fabric network v1.0.
• Manage a pool of operational blockchain networks across bare metals, virtual clouds (like virtual machines and vSphere Clouds), and container clusters (like Docker, Swarm, and Kubernetes).
• Observe system status, optimize chain numbers, and scale resources via intuitive dashboards.

A typical usage scenario is illustrated below:

Main Features

• Manage the lifecycle of blockchains: create, start, stop, delete, and maintain health automatically.
• Support for customized blockchain requests (size, consensus); currently focusing primarily on Hyperledger Fabric.
• Compatibility with native Docker host, Swarm, or Kubernetes as worker nodes, with more support to come.
• Support for heterogeneous architecture, including X86, POWER, and Z, from bare-metal servers to virtual machines.
• Enhance performance with monitoring, logging, health, and analytics features through additional components.

Quick Start

Let’s dive into getting Hyperledger Cello up and running.

Environmental Preparation:

1. Install Docker
2. Install Docker Compose V2
3. Verify that the make all script for Cello service management is written in the Makefile.
4. Optionally, install Kubernetes.
5. Install Node.js.

Starting the Cello Service:

Once everything is in place, follow these steps:

1. Set the local storage environment variable, using the current path as a storage path:

export CELLO_STORAGE_PATH=$(pwd)

2. Start the service locally:

make local

3. Optional: Build essential images for Cello service:

make docker

4. Run services locally:

make start

5. Check the output for confirmation:

6. To stop the service:

make stop

7. To clean all containers:

make clean

8. To check available make rules:

make help

9. Visit the Cello dashboard at localhost:8081.
10. Refer to the troubleshoot section for any issues encountered.

Troubleshooting Ideas

If you face any challenges, consider the following:

• Ensure that all environmental dependencies are met before starting the service.
• Check Docker and Docker Compose configurations to avoid version compatibility issues.
• Monitor the console output for errors or warnings during the service startup.
• If using Kubernetes, make sure the configurations are aligned with your cluster settings.
