How to Launch the Hyperledger Fabric Network to run the WYFA (Writing Your First Application) tutorial?

You can follow these steps to Launch the Hyperledger Fabric Network to run the WYFA (Writing Your First Application) tutorial.

1. Run the startFabric.sh script to spin up a blockchain network, create a channel and deploy a chaincode:

$ cd ~/hyperledger-binaries/fabric-samples/fabcar

$ ./startFabric.sh  javascript

# don't rewrite paths for Windows Git Bash users
export MSYS_NO_PATHCONV=1

docker-compose -f docker-compose.yml down
Removing network net_basic
WARNING: Network net_basic not found.

docker-compose -f docker-compose.yml up -d ca.example.com orderer.example.com \
   peer0.org1.example.com couchdb
Creating network "net_basic" with the default driver
Creating orderer.example.com ... done
Creating couchdb             ... done
Creating ca.example.com      ... done
Creating peer0.org1.example.com ... done

export FABRIC_START_TIMEOUT=10
sleep ${FABRIC_START_TIMEOUT}

# Create the channel
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" ...\
   peer channel create -o orderer.example.com:7050 \
   -c mychannel -f /etc/hyperledger/configtx/channel.tx

[channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
[cli.common] readBlock -> INFO 002 Received block: 0

# Join peer0.org1.example.com to the channel.
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" ...\
   peer channel join -b mychannel.block

[channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
[channelCmd] executeJoin -> INFO 002 Successfully submitted proposal to join channel
Creating cli ... done

[chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
[chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc
[chaincodeCmd] submitInstallProposal -> INFO 003 Installed remotely: response:<status:200 payload:"OK" >
[chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
[chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc

Error: could not assemble transaction, err proposal response was not 
successful, error code 500, msg error starting container: error starting 
container: Failed to generate platform-specific docker build: Failed to 
pull hyperledger/fabric-nodeenv:latest: API error (404): manifest for 
hyperledger/fabric-nodeenv:latest not found

The script failed late in the process. So the WYFA network is almost running.

2. Verify Docker containers running for the WYFA network:

$ docker ps -a

IMAGE                       STATUS         NAMES

hyperledger/fabric-tools    Up 15 minutes  cli
hyperledger/fabric-peer     Up 15 minutes  peer0.org1.example.com
hyperledger/fabric-ca       Up 15 minutes  ca.example.com
hyperledger/fabric-couchdb  Up 15 minutes  couchdb
hyperledger/fabric-orderer  Up 15 minutes  orderer.example.com

 

⇒ Verify the WYFA Network

⇐ Clean Up Docker Engine for WYFA
