## 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:

![Typical Scenario](docs/images/scenario.png)

## Quick Start

Environmental preparation:

1. docker [how install](https://get.docker.com)
2. docker compose(`we switched to` [Docker Compose V2](https://docs.docker.com/compose/#compose-v2-and-the-new-docker-compose-command)) [how install](https://docs.docker.com/compose/install/)
3. make `all script for cello service management is written in Makefile`
4. kubernetes (`optional`) [how install](https://kubernetes.io/docs/setup/)
5. node [how install](https://nodejs.org/en/download/)

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

* Set local storage environment variable, e.g. Use current path as storage path

```bash
$ export CELLO_STORAGE_PATH=$(pwd)/cello
```

* Start service locally

```bash
$ make local
```

* Optional: Build essential images for cello service (the docker hub image auto build haven't ready, in the future you can ignore this step.)

* Build docker images
```bash
$ make docker
```
* Then run services locally then

```bash
$ make start
```

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

```bash

```

* Stop cello service.

```bash
$ make stop
```

* Clean all containers

```bash
$ make clean
```

* Check available make rules

```bash
$ make help
```

* Visit Cello dashboard at `localhost:8081`

* Check [troubleshoot](https://github.com/hyperledger/cello/blob/main/docs/setup/server.md#3-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](https://github.com/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 [documentation](docs/index.md) first.

And feel free to visit the [online documentation](http://cello.readthedocs.io/en/latest/) for more information. You can also run `make doc` to start a local documentation website (Listen at [localhost:8000](http://127.0.0.1:8000).

## Why named Cello?

Can you find anyone better at playing chains? :)

## Incubation Notice

This project is a Hyperledger project in _Incubation_. It was proposed to the community and documented [here](https://docs.google.com/document/d/1E2i5GRqWsIag7KTxjQ_jQdDiWcuikv3KqXeuw7NaceM/edit), and was approved by [Hyperledger TSC at 2017-01-07](https://lists.hyperledger.org/pipermail/hyperledger-tsc/2017-January/000535.html). Information on what _Incubation_ entails can be found in the [Hyperledger Project Lifecycle document](https://goo.gl/4edNRc).

## Inclusive Language Statement

These guiding principles are very important to the maintainers and therefore
we respectfully ask all contributors to abide by them as well:

* Consider that users who will read the docs are from different backgrounds and
cultures and that they have different preferences.
* Avoid potential offensive terms and, for instance, prefer "allow list and
deny list" to "white list and black list".
* We believe that we all have a role to play to improve our world, and even if
writing inclusive documentation might not look like a huge improvement, it's a
first step in the right direction.
* We suggest to refer to
[Microsoft bias free writing guidelines](https://docs.microsoft.com/en-us/style-guide/bias-free-communication)
and
[Google inclusive doc writing guide](https://developers.google.com/style/inclusive-documentation)
as starting points.
