Hyperledger on multiple physical machines

Domains:

• orderer: orderer.vlf.zx.rs
• CA server: ca.vlf.zx.rs
• peer 0 (163.172.153.65): peer0.vlf.zx.rs
• peer 1 (163.172.153.65): peer1.vlf.zx.rs
• peer 2 (46.101.239.172): peer2.vlf.zx.rs

Starting the network

(mostly from here)

Install docker

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
sudo apt-get install -y docker-ce

Install docker composer

curl -L https://github.com/docker/compose/releases/download/1.19.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

Bootstrap hyperledger (current 1.0.6)

curl https://raw.githubusercontent.com/hyperledger/fabric/release/scripts/bootstrap.sh > bootstrap.sh
chmod +x bootstrap.sh
./bootstrap.sh

Install nodejs

curl -sL https://deb.nodesource.com/setup_9.x | sudo -E bash -
sudo apt-get install -y nodejs

Install build essentials

sudo apt-get install -y build-essential

Install composer-cli

npm install -g composer-cli --unsafe-perm

Clone this repo

git clone https://github.com/anbud/hyperledger-multi

If something changes in crypto-config.yaml

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

If something changes in configtx.yaml

export FABRIC_CFG_PATH=$PWD
configtxgen -profile ComposerOrdererGenesis -outputBlock ./composer-genesis.block
configtxgen -profile ComposerChannel -outputCreateChannelTx ./composer-channel.tx -channelID composerchannel

Machine-specific commands

On machine 1

./teardownFabric.sh && ./startFabric.sh && ./createPeerAdminCard.sh

On machine 2

./startFabric-Peer2.sh

Deploying chain code (marbles02)

Docker

(it doesn't work without fabric-tools docker container)

docker run -d --name cli -v /:/etc/opt -t hyperledger/fabric-tools:x86_64-1.0.6
docker exec -it cli /bin/bash

Setting up variables

export CORE_PEER_LOCALMSPID=VLFMSP
export CORE_PEER_MSPCONFIGPATH=/etc/opt/root/hyperledger-multi/composer/crypto-config/peerOrganizations/vlf.zx.rs/users/Admin@vlf.zx.rs/msp
export CORE_PEER_ADDRESS=peer2.vlf.zx.rs:9051

Get the marbles02 example

go get github.com/hyperledger/fabric/examples/chaincode/go/marbles02

Install the chaincode

peer chaincode install -n marbles -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/marbles02 --cafile /etc/opt/root/hyperledger-multi/composer/crypto-config/ordererOrganizations/vlf.zx.rs/orderers/orderer.vlf.zx.rs/msp/tlscacerts/tlsca.vlf.zx.rs-cert.pem -o orderer.vlf.zx.rs:7050

Instantiate the chaincode

peer chaincode instantiate -n marbles -v 1.0 -C composerchannel -c '{"Args":["init"]}' -P "OR ('VLFMSP.member')" --cafile /etc/opt/root/hyperledger-multi/composer/crypto-config/ordererOrganizations/vlf.zx.rs/orderers/orderer.vlf.zx.rs/msp/tlscacerts/tlsca.vlf.zx.rs-cert.pem -o orderer.vlf.zx.rs:7050

Invoke sample commands

peer chaincode invoke -C composerchannel -n marbles -c '{"Args":["initMarble","marble1","blue","35","tom"]}' -o orderer.vlf.zx.rs:7050
peer chaincode invoke -C composerchannel -n marbles -c '{"Args":["initMarble","marble2","red","50","tom"]}' -o orderer.vlf.zx.rs:7050
peer chaincode invoke -C composerchannel -n marbles -c '{"Args":["initMarble","marble3","blue","70","tom"]}' -o orderer.vlf.zx.rs:7050
peer chaincode invoke -C composerchannel -n marbles -c '{"Args":["transferMarble","marble2","jerry"]}' -o orderer.vlf.zx.rs:7050
peer chaincode invoke -C composerchannel -n marbles -c '{"Args":["transferMarblesBasedOnColor","blue","jerry"]}' -o orderer.vlf.zx.rs:7050
peer chaincode invoke -C composerchannel -n marbles -c '{"Args":["delete","marble1"]}' -o orderer.vlf.zx.rs:7050

Query the results

peer chaincode query -C composerchannel -n marbles -c '{"Args":["readMarble","marble1"]}' -o orderer.vlf.zx.rs:7050

Error: Error endorsing query: rpc error: code = Unknown desc = chaincode error (status: 500, message: {"Error":"Marble does not exist: marble1"}) - (it was deleted before)

peer chaincode query -C composerchannel -n marbles -c '{"Args":["getMarblesByRange","marble1","marble3"]}' -o orderer.vlf.zx.rs:7050

Query Result: {"color":"red","docType":"marble","name":"marble2","owner":"jerry","size":50}

peer chaincode query -C composerchannel -n marbles -c '{"Args":["getHistoryForMarble","marble1"]}' -o orderer.vlf.zx.rs:7050
