Generating the crypto material for all the organizations

See Bootstrapping the Hyperledger Fabric Network (Part 1)

# You will find `cryptogen` in the `bin` folder created in the directory in which you
# executed `curl -sSL https://goo.gl/iX9dek | bash`
cryptogen generate --config=./crypto-config.yaml

Generating the Orderer genesis block

See Bootstrapping the Hyperledger Fabric Network (Part 2)

# You will find `configtxgen` in the `bin` folder created in the directory in which you
# executed `curl -sSL https://goo.gl/iX9dek | bash`
#
# Also make sure to set the FABRIC_CFG_PATH environment variable (it is required by configtxgen tool)
#
export FABRIC_CFG_PATH=$PWD
configtxgen -profile ThreeOrgsOrdererGenesis -outputBlock ./genesis.block

You can directly use the docker-compose command as specified in the blog post or using the command that I have hooked up in the package.json. The npm command also deletes 'production' folder so that every time your start the orderer node it starts with clean content.

npm run start-orderer

Similarly to stop the orderer containers simply issue

npm run stop-orderer

Generating the channel configuration transaction

See Bootstrapping the Hyperledger Fabric Network (Part 3)

configtxgen -profile ThreeOrgsChannel -outputCreateChannelTx ./ksachdeva-exp-channel-1.tx -channelID ksachdeva-exp-channel-1

Creating the new channel

See Bootstrapping the Hyperledger Fabric Network (Part 4)

npm run create-channel

Make Peers join the new channel

See Bootstrapping the Hyperledger Fabric Network (Part 5)

# Stop already running orderer containers
npm run stop-containers
# This will start both orderer & peer containers
npm run start-containers
# Create the channel again as when we start-containers we remove the previous data from the containers
npm run create-channel
# Join the channel
npm run join-channel

Install and instantiate the chaincode

See Bootstrapping the Hyperledger Fabric Network (Part 6)

npm run install-chaincode
npm run instantiate-chaincode

Invoke the transaction & Query the chaincode

See Invoking a transaction on Hyperledger Fabric Network

npm run query-chaincode
npm run invoke-transaction
npm run query-chaincode
