채널 생성

export CHANNEL_NAME=mychannel

# the channel.tx file is mounted in the channel-artifacts directory within your CLI container
# as a result, we pass the full path for the file
# we also pass the path for the orderer ca-cert in order to verify the TLS handshake
# be sure to export or replace the $CHANNEL_NAME variable appropriately

peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

채널 조인

# By default, this joins ``peer0.org1.example.com`` only
# the <CHANNEL_NAME.block> was returned by the previous command
# if you have not modified the channel name, you will join with mychannel.block
# if you have created a different channel name, then pass in the appropriately named block

 peer channel join -b mychannel.block

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp CORE_PEER_ADDRESS=peer0.org2.example.com:7051 CORE_PEER_LOCALMSPID="Org2MSP" CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt peer channel join -b mychannel.block

-> 실행 결과

update the anchor peers

peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org1MSPanchors.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

-> 실행 결과

Install & Instantiate Chaincode

Node.js 를 이용해 설치 후 인스턴스화

peer chaincode install -n mycc -v 1.0 -l node -p /opt/gopath/src/github.com/chaincode/chaincode_example02/node/

peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n mycc -l node -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')"

-> 실행 결과

peer2의 환경변수 설정

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
CORE_PEER_ADDRESS=peer0.org2.example.com:7051

Query & Invoke

a라는 값을 가지는 쿼리 날리기

peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}'

-> 실행 결과

Invoke - 10을 a에서 b로 옮기기

peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["invoke","a","b","10"]}'

-> 실행결과

다시 쿼리를 날렸을때 잘 옮겨졌음을 알 수 있다.
