Finally Lets run our Network

Without Couchdb

docker-compose -f docker-compose.yaml up

With Couchdb

docker-compose -f docker-compose-test-net.yaml -f docker-compose-couch.yaml up

Include monitor.sh file to monitor logs from all the containers

./scripts/monitordocker.sh <network_name> ./scripts/monitordocker.sh fabric_test

Chaincode

=====================================

1. Golang

Initializing Module

go mod init fabcar.go

Building Chaincode

go build

GO111MODULE=on go mod vendor

---

Chaincode Lifecycle

Note:-

Set bin path & FABRIC_CFG_PATH

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

export FABRIC_CFG_PATH=$PWD/

Step one: Package the smart contract

peer lifecycle chaincode package chaincode.tar.gz --path ./chaincode/go/ --lang golang --label chaincode01_1.0

peer lifecycle chaincode package fabcar_1.0.tar.gz --path ./chaincode/go/ --lang golang --label fabcar_1.0

peer lifecycle chaincode package fabcar_1.0.tar.gz --path ./chaincode/go/ --lang node --label fabcar_1.0

2. Typescript

peer lifecycle chaincode package basic.tar.gz --path ./chaincode/typescript/ --lang node --label basic_1.0

Step two: Install the chaincode package

Set env variables to Org 1:

export CORE_PEER_TLS_ENABLED=true export CORE_PEER_LOCALMSPID="Org1MSP" export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/[email protected]/msp export CORE_PEER_ADDRESS=localhost:7051

peer lifecycle chaincode install chaincode.tar.gz

Set env variables to Org 2:

export CORE_PEER_LOCALMSPID="Org2MSP" export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/[email protected]/msp export CORE_PEER_ADDRESS=localhost:9051

peer lifecycle chaincode install chaincode.tar.gz

Querying the Chaincode

peer lifecycle chaincode queryinstalled

export CC_PACKAGE_ID=<package_id>

Step three: Approve a chaincode definition

As Org 2

peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name basic --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

As Org 1

export CORE_PEER_LOCALMSPID="Org1MSP" export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/[email protected]/msp export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt export CORE_PEER_ADDRESS=localhost:7051

peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name basic --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

Step four: Committing the chaincode definition to the channel

Check Commit Readiness

peer lifecycle chaincode checkcommitreadiness --channelID mychannel --name basic --version 1.0 --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --output json

Step five: Commit Chaincode

peer lifecycle chaincode commit -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name basic --version 1.0 --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt

Query Committed (Approvals)

peer lifecycle chaincode querycommitted --channelID mychannel --name basic --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

Invoking the Chaincode

peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n basic --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.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 '{"function":"InitLedger","Args":[]}'

Commands to invoke | query chaincode

Query All Cars

peer chaincode query -C mychannel -n basic -c '{"Args":["queryAllCars"]}'

===============================

Note:- Query works without any other parameters, but invoke needs to provide all parameters

===============================

Create Car

peer chaincode invoke -C mychannel -n basic -c '{"Args":["createCar", "CAR10", "Pak", "My-Car", "Black", "Subhan"]}' --waitForEvent -o localhost:7050 --peerAddresses=localhost:7051 --peerAddresses=localhost:9051 --tlsRootCertFiles organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --tlsRootCertFiles organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt --tls --cafile organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

Update Car

peer chaincode invoke -C mychannel -n basic -c '{"Args":["ChangeCarOwner", "CAR10", "Subhan ***"]}' --waitForEvent -o localhost:7050 --peerAddresses=localhost:7051 --peerAddresses=localhost:9051 --tlsRootCertFiles organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --tlsRootCertFiles organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt --tls --cafile organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

Upgrading the Chaincode

peer lifecycle chaincode package fabcar_2.0.tar.gz --path chaincode/javascript/ --lang node --label fabric_2.0
