Adding a new in running Hyperledger Fabric Network

Starting the network

Creating channel

./network.sh up createChannel -ca -c mychannel -s couchdb

Installing Chaincode

./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go

Setting up environment variable

export PATH=${PWD}/../bin:$PATH
export FABRIC_CFG_PATH=${PWD}/../config

export ORDERER_CA=${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp

export CORE_PEER_ADDRESS=localhost:7051

export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt

export CORE_PEER_LOCALMSPID=Org1MSP

Invoke CC

peer chaincode invoke -n basic -C mychannel -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com  --tls --cafile "$ORDERER_CA" --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer1.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt  -c '{"Args":["CreateAsset", "100","red", "20","aditya","100"]}'

Query CC

peer chaincode query -n basic -C mychannel -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com  -c '{"Args":["ReadAsset", "100"]}'

Setting up the new peer

Creating MSP Identities for peer1.org1.example.com

./organizations/fabric-ca/registerPeer1.sh

Starting up the peer container

docker-compose -f docker/docker-compose-peer1.yaml up -d

Joining existing channel

Query channel on peer0.org1.example.com

peer channel list
peer channel fetch -c mychannel newest
CORE_PEER_ADDRESS=localhost:8051 peer channel getinfo -c mychannel

Query channel on peer1.org1.example.com

CORE_PEER_ADDRESS=localhost:8051 peer channel list
CORE_PEER_ADDRESS=localhost:8051 peer channel fetch -c mychannel newest
CORE_PEER_ADDRESS=localhost:8051 peer channel getinfo -c mychannel

Join channel

CORE_PEER_ADDRESS=localhost:8051 peer channel join -b ./channel-artifacts/mychannel.block

Query channel on peer1.org1.example.com

CORE_PEER_ADDRESS=localhost:8051 peer channel list
CORE_PEER_ADDRESS=localhost:8051 peer channel fetch -c mychannel newest
CORE_PEER_ADDRESS=localhost:8051 peer channel getinfo -c mychannel

Chaincode Setup

Install CC
