Intro

人工链圈 - Artificial chain

Run release-1.1

Start the network(In Terminal)

/home/tao/software/opt/Go/src/github.com/hyperledger/fabric-samples/
docker-compose -f docker-compose-cli.yaml up -d
  • this copys the chaincode dir
cd /home/tao/software/opt/Go/src/
docker cp cvChain 49f92f126b1d:/opt/gopath/src/github.com/

Start the network(In Docker)

  • this sets configuration
docker exec -it cli bash
export CHANNEL_NAME=mychannel
export NAME=cc
export ENCKEY=`openssl rand 32 -base64` && DECKEY=$ENCKEY
export IV=`openssl rand 16 -base64`
  • Create & Join Channel
peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
  • Install & Instantiate Chaincode
peer chaincode install -n $NAME -v 1.0 -p github.com/cvChain/
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 $NAME -v 1.0 -c '{"Args":["init",""]}' -P "OR ('Org1MSP.peer','Org2MSP.peer')"
