Hyperledger Fabric

Basic structure of a Hyperledger Fabric Project

To run this project it's necessary to install Hyperledger Fabric prerequisites describe in this https://hyperledger-fabric.readthedocs.io/en/release-1.4/prereqs.html

To build the network and deploy the smart contract

./startFabric

List the smart contracts installed

peer chaincode list --installed -C mychannel

To update the smart contract

docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp" -it cli bash

peer chaincode install -n bart -v 1.1 -p /opt/gopath/src/github.com/bart -l node

peer chaincode upgrade -o orderer.example.com:7050 -C mychannel -n bart -v 1.1 -c '{"Args": []}' -P "OR ('Org1MSP.member','Org2MSP.member')"

peer chaincode invoke -o orderer.example.com:7050 -C mychannel -n bart -c '{"function":"initLedger","Args":[]}'

Global Variables

if version not passed in, default to latest released version

Parse commandline args pull out

version and/or ca-version strings first

if [ -n "$1" ] && [ "${1:0:1}" != "-" ]; then VERSION=$1;shift if [ -n "$1" ] && [ "${1:0:1}" != "-" ]; then CA_VERSION=$1;shift if [ -n "$1" ] && [ "${1:0:1}" != "-" ]; then THIRDPARTY_IMAGE_VERSION=$1;shift fi fi fi

prior to 1.2.0 architecture was determined by uname -m

if [[ $VERSION =~ ^1.[0-1].* ]]; then export FABRIC_TAG=${MARCH}-${VERSION} export CA_TAG=${MARCH}-${CA_VERSION} export THIRDPARTY_TAG=${MARCH}-${THIRDPARTY_IMAGE_VERSION} else # starting with 1.2.0, multi-arch images will be default : "${CA_TAG:="$CA_VERSION"}" : "${FABRIC_TAG:="$VERSION"}" : "${THIRDPARTY_TAG:="$THIRDPARTY_IMAGE_VERSION"}" fi
