Overview
The purpose of this demonstrator is to help you appreciate the process of setting up a Kafka based Hyperledger Fabric network.
Please refer to Fabric’s official document on Kafka based Fabric network
The demonstrator has been verified to work on macOS these versions of Hyperledger Fabric components:
| Component | Version |
|---|---|
| FABRIC CA | 1.4.0 |
| PEER | 1.4.0 |
| ORDERER | 1.4.0 |
| COUCHDB | 0.4.8 |
| FABRIC_TOOL | 1.4 |
| KAFKA | 0.4.16 |
| ZOOKEEPER | 0.4.16 |
| macOS | Catalina |
| Docker | version 19.03.4, build 9013bf5 |
Scenario
This network uses a cluster of two orderers curated by a combination of Kafka and zookeepers. The network also comprises of two organisations. Each organisation owns a peer node, Fabric CA and a cli. The two organisation transact wtith each other via two channels.
Steps to configure a Kafka network
STEP 1: git clone https://github.com/fabric-devkit/core-platform and navigate to the folder named kafka.
STEP 2: Run the command fabricOps.sh kafka start to start Kafka cluster.
STEP 3: Run the command fabricOps.sh network start followed by fabricOps.sh configure to instantiate a Hyperledger Fabric network.
