Introduction

Using Cello, everyone can easily:

• Build up a Blockchain as a Service (BaaS) platform quickly from scratch.
• Provision customizable Blockchains instantly, e.g., a Hyperledger fabric network v1.0.
• Maintain a pool of running blockchain networks on top of baremetals, Virtual Clouds (e.g., virtual machines, vsphere Clouds), Container clusters (e.g., Docker, Swarm, Kubernetes).
• Check the system status, adjust the chain numbers, scale resources... through dashboards.

A typical usage scenario is illustrated as:

Quick Start

Environmental preparation:

1. docker how install
2. docker-compose how install
3. make all script for cello service management is written in Makefile
4. kubernetes (optional) how install

If environment is prepared, then we can start cello service.

• Build essential images for cello service (Optional, because currently the dockerhub image auto build haven't ready, in the future you can ignore this step.)

# make docker

• config variables for service deployment through menuconfig/alldefconfig, then will generate .config file under the project folder.

if you want to use default configuration for service deployment, only need run alldefconfig.

# make alldefconfig

if you want to set the config through terminal ui, run menuconfig .

# make menuconfig

• Start cello service, default deployment method is using docker-compose, if you have kubernetes environment, you can change deployment method to kubernetes through DEPLOY_METHOD=k8s make start.

# make start

After service started up, if use docker-compose method, you can see output:

If use kubernetes method to deploy, the output is:

If you visit the dashboard through 8081 port, the default username/password is admin/pass.

• Stop cello service, same as start, need set the DEPLOY_METHOD variable.

# make stop

Main Features

• Manage the lifecycle of blockchains, e.g., create/start/stop/delete/keep health automatically.
• Support customized (e.g., size, consensus) blockchains request, currently we mainly support Hyperledger fabric.
• Support native Docker host, swarm or Kubernetes as the worker nodes. More supports on the way.
• Support heterogeneous architecture, e.g., X86, POWER and Z, from bare-metal servers to virtual machines.
• Extend with monitor, log, health and analytics features by employing additional components.

Documentation, Getting Started and Develop Guideline

For new users, it is highly recommended to read the tutorial or index first.

And feel free to visit the online documentation for more information. You can also run make doc to start a local documentation website (Listen at localhost:8000.

Why named Cello?

Can you find anyone better at playing chains? :)
