VOTING CHAINCODE DEPLOY

Execute the following instructions serial.

Vagrant dev env

Instructions

First of all log in vagrant:

  • cd ~/go/src/github.com/hyperledger/fabric/devenv/
  • vagrant up
  • vagrant ssh

Download fabric-sample

  • Create a directory where you want to. mkdir fabric-sample
  • cd fabric-sample
  • Execute : curl -sSL https://goo.gl/LQkuoh | bash

Deploy

  • cd release/linux-amd64$

  • ./network_setup.sh down - needed in case it's not the first time deploying.

  • ./generateArtifacts.sh mychannel

  • vi docker_compose_cli.yaml - needed in case it's the first time deploying.

    And comment the following line: command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME}; sleep $TIMEOUT'. Your file should look like this:

     working_dir: /opt/gopath/src/github.com/hyperledger/fabric/peer
 # command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME}; sleep $TIMEOUT'
 volumes

  • CHANNEL_NAME=mychannel TIMEOUT=3600 docker-compose -f docker-compose-cli.yaml up -d

  • docker exec -it cli bash

  • peer channel create -o orderer.example.com:7050 -c mychannel -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/cacerts/ca.example.com-cert.pem

  • peer channel join -b mychannel.block

  • go get github.com/giou-k/Voting

  • peer chaincode install -n mycc -v 1.0 -p github.com/giou-k/Voting

  • peer chaincode instantiate -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/cacerts/ca.example.com-cert.pem -C mychannel -n mycc -v 1.0 -p github.com/giou-k/Voting -c '{"Args":[]}' -P "OR ('Org1MSP.member','Org2MSP.member')"

  • After the instantiation you can see logs.

Logs

  • docker ps
  • docker logs -f <container id> . The <container id> will have as <image> yours chaincode name (ex: mycc) after the instantiation of the CC.

Test Init

  • peer chaincode invoke -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/cacerts/ca.example.com-cert.pem -C mychannel -n mycc -c '{"Args":["init","314"]}'
