Getting Started with Hyperledger Fabric Demo

You will need to run through the following:

Prerequisites

• Docker
• Node
• Yarn

Build

start off in root folder

yarn install

cd fabric-scripts/build

./startBuild.sh 

Answer y to the docker cache question

If you are running this on a smaller server and the build fails, change the timeout param in the startBuild.sh script to something much bigger (e.g. 100) and try again

Back to Root Folder

cd ../../

Run App

node app

http://localhost:3000

    partNumber: '2',
    manufacturerName: 'geminiParts',
    cageCode: '1',
    faaApprovalCode: '1',
    description: 'Spark Plug',
    revision: '1',
    drawingNumber: '1',
    quantity: '1',
    uom: 'm',
    batchNumber: '1',
    grDate: '15/06/2018',
    status: 'done',
    owner: 'geminiParts',
    location: 'engine',
    parentPart: '',

}

Query Manufacturer

/getParts?manufacturerName={manufacturerName}

    owner: 'cgAutoz'
}

/changeStatus POST

{
    serialNumber: '1',
    partNumber: '2',
    manufacturerName: 'geminiParts',
    status: 'error'
}

Upgrade Chaincode

After updating the chaincode program fabric-scripts/chaincode/fabpart/node/fabpart.js

Upgrade (increment version number)

Install

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

Then Upgrade

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