Multi-Host Deployment for First Network (Hyperledger Fabric v2)

Overview

Setup

Demonstration

Step 1: Bring up four hosts in AWS

Step 2: Create an overlay with Docker Swarm

docker swarm init --advertise-addr <host-1 ip address>
docker swarm join-token manager
<output from join-token manager> --advertise-addr <host n ip>
docker network create --attachable --driver overlay first-network
Terminals for Host 1, 2, 3 and 4 (from top to bottom)

Step 3: Clone the repository on all hosts

cd fabric-samples
git clone https://github.com/kctam/4host-swarm.git
cd 4host-swarm

Step 4: Bring up each host

./hostnup.sh
Containers in Host 1, 2, 3 and 4 (from top to bottom)

Step 5: Bring up mychannel and join all peers to mychannel

./mychannelup.sh
docker exec peerx.orgy.example.com peer channel getinfo -c mychannel
All peers have the same ledger (blockchain) after joining mychannel

Step 6: Deploy fabcar chaincode

# If not done before
pushd ../chaincode/fabcar/go
GO111MODULE=on go mod vendor
popd
# packaging
docker exec cli peer lifecycle chaincode package fabcar.tar.gz --path github.com/chaincode/fabcar/go --label fabcar_1
# peer0.org1
docker exec cli peer lifecycle chaincode install fabcar.tar.gz
# peer1.org1
docker exec -e CORE_PEER_ADDRESS=peer1.org1.example.com:8051 -e CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer1.org1.example.com/tls/ca.crt cli peer lifecycle chaincode install fabcar.tar.gz
# peer0.org2
docker exec -e CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp -e CORE_PEER_ADDRESS=peer0.org2.example.com:9051 -e CORE_PEER_LOCALMSPID="Org2MSP" -e CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt cli peer lifecycle chaincode install fabcar.tar.gz
# peer1.org2
docker exec -e CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp -e CORE_PEER_ADDRESS=peer1.org2.example.com:10051 -e CORE_PEER_LOCALMSPID="Org2MSP" -e CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/tls/ca.crt cli peer lifecycle chaincode install fabcar.tar.gz
Chaincode container images are built after chaincode package is installed on each peer.
