This is a folked repository from https://github.com/hyperledger/fabric-samples/tree/release/first-network with Kafak order type integrated.
Before drilling into this demo, please make sure you are very well understanding the offical Hyperledger Fabric "Build Your First Network" tutorial.
1.0.4
Download the necessary binaries (You may skip it if you have done it before).
Go to root folder,
./get-byfn.sh
Pull the farbric docker images. (You may skip it if you have done it before).
Go to root folder,
./get-docker-images.sh
cd first-network
# Start up network
./byfn.sh up
You will see log like:
Starting with channel 'mychannel' and CLI timeout of '10' seconds and CLI delay of '3' seconds
Continue? [Y/n] Y

# Available types are "solo" and "kafka"
OrdererType: kafka
....
Kafka:
# Brokers: A list of Kafka brokers to which the orderer connects
# NOTE: Use IP:port notation
Brokers:
- kafka0.example.com:9092
- kafka1.example.com:9092
- kafka2.example.com:9092
- kafka3.example.com:9092
Be noticed that zookeepers and kafkas are added, be sure they are with byfn network:
networks:
- byfn
Orderer should be started up after kafkas
orderer.example.com:
extends:
file: base/docker-compose-base.yaml
service: orderer.example.com
container_name: orderer.example.com
depends_on:
- kafka0.example.com
- kafka1.example.com
- kafka2.example.com
- kafka3.example.com
networks:
- byfn
Add zookeepers & kafka nodes
Check the source code from them.
Update COMPOSE_FILE:
# use this as the default docker-compose yaml definition
COMPOSE_FILE=docker-compose-kafka.yaml
Sleep some time before bring up docker containers:
# Generate the needed certificates, the genesis block and start the network.
function networkUp () {
....
....
# now run the end to end script
sleep 5 # <== Check this line
docker exec cli scripts/script.sh $CHANNEL_NAME $CLI_DELAY $LANGUAGE $CLI_TIMEOUT
if [ $? -ne 0 ]; then
echo "ERROR !!!! Test failed"
exit 1
