Hyperledger fabric 1.0.4
Here we show steps on how to setup a fabric 1.0.4 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 startmake initmake test_ccmake 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
example02for 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

Test Chaincode
$ make test_cc # test invoke and query with chaincode
More details, see chaincode test.
Stop the network
$ make stop # stop the fabric network
Clean environment
Clean all related containers and images.
$ make clean # clean the environment
