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:

docker how install
docker compose(we switched to Docker Compose V2) how install
make all script for cello service management is written in Makefile
kubernetes (optional) how install
node 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.)
- Build API Engine
```
$ make api-engine
```
- Build Docker Agent
```
$ make docker-rest-agent
```
- Build Docker Dashboard
```
$ make dashboard
```

Start cello service.

$ make start

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

Stop cello service.

$ make stop

Check troubleshoot section if you get any question.

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.

Can you find anyone better at playing chains? :)
