Hyperledger fabric 1.0.2

Here we show steps on how to setup a fabric 1.0.2 network on Linux (e.g., Ubuntu/Debian), and then use it to run chaincode tests.

If you're not familiar with Docker and Blockchain technology yet, feel free to have a look at 2 books (in CN):

Pass-through

The following command will run the entire process (start a fabric network, create channel, test chaincode and stop it.) pass-through.

$ make setup # install docker/compose, and pull required images
$ make all

tldr :)

make all actually call following command sequentially.

  • make start
  • make init
  • make test_cc
  • make stop

Otherwise, if u wanna know more or run the command manually, then go on reading the following part.

Environment Setup

The following scripts will setup the environment by installing Docker, Docker-Compose and download required docker images.

$ make setup # setup environment

If you want to setup the environment manually, then have a look at manually setup.

Bootup Fabric Network

Start a 4 peer (belonging to 2 organizations) fabric network.

$ make start  # Start a fabric network

The script actually uses docker-compose to boot up the fabric network with several containers.

There will be 7 running containers, include 4 peers, 1 cli, 1 ca and 1 orderer.

$ make ps

Initialize Fabric network

$ make init  # Start a fabric network

The command actually calls the ./scripts/initialize.sh script in the fabric-cli container to:

  • create a new application channel businesschannel
  • join all peers into the channel
  • install and instantiate chaincode example02 for testing

This script only needs to be executed once.

You should see result like the following if the initialization is successful.

==============================================
==========initialize businesschannel==========
==============================================

Channel name : businesschannel
Creating channel...

...

===================== All GOOD, initialization completed =====================

And there will be new chaincode container generated in the system, looks like

$ make ps
