Fabric_Build Your First Network

*

* Generating certs and genesis block for with channel 'mychannel' and CLI timeout of '10'

*

./byfn.sh -m generate

*

* Bring the network up, compile Golang chaincode images and spin up the corresponding containers.

* launch all of the containers, and then drive a complete end-to-end application scenario

*

./byfn.sh -m up

*

* Bring down the network up kill your containers, remove the crypto material and four artifacts,

* and delete the chaincode images from your Docker Registry

*

./byfn.sh -m down

*

* generate the keys/ certs for network configuration defined in ctypto-config.yaml

*

../bin/cryptogen generate --config=./crypto-config.yaml

*

* 1. Tell the configtxgen tool where the configtx.taml

* 2. To create the orderer genesis block;

*

export FABRIC_CFG_PATH=$PWD;

../bin/configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

*

* Create Channel Configuration Transaction

*

export CHANNEL_NAME=mychannel  && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME

*

* Define the anchor peer for Org1 on the above channel by specifying -channelID flag

*

../bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP

*

* Define the anchor peer for Org2 on the above channel by specifying -channelID flag

../bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP

*

* Start above defined network

*

docker-compose -f docker-compose-cli.yaml up -d

docker exec -it cli bash

*

* Within started cli console

* 'root@0d78bb69300d:/opt/gopath/src/github.com/hyperledger/fabric/peer#'

* to create a channel

*

----------------------------------------------------

export CHANNEL_NAME=mychannel

# the channel.tx file is mounted in the channel-artifacts directory within your CLI container

# as a result, we pass the full path for the file

# we also pass the path for the orderer ca-cert in order to verify the TLS handshake

# be sure to export or replace the $CHANNEL_NAME variable appropriately

peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --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

----------------------------------------------------

*

*  Let peer0.org1.example.com to join the channel.

*

peer channel join -b mychannel.block

*

* Change environment variables

* Let peer0.org2.example.com to join the channel.

Install & Instantiate Chaincode

*

* Install chaincode for GoLang

*

peer chaincode install -n mycc -v 1.0 -p github.com/chaincode/chaincode_example02/go/

*

* Instantiate chaincode for GoLang

*

# be sure to replace the $CHANNEL_NAME environment variable if you have not exported it

# if you did not install your chaincode with a name of mycc, then modify that argument as well

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 mycc -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}' -P "OR ('Org1MSP.peer','Org2MSP.peer')"
