피어노드 추가

네트워크 구조

• 기존 네트워크 구조

Orderer : orderer.example.com 1개 존재
Org1 : peer0, peer1 존재
Org2 : peer0, peer1 존재

• 변경된 네트워크 구조

Orderer : orderer.example.com 1개 존재
Org1 : peer0, peer1, peer2 존재
Org2 : peer0, peer1, peer2, peer3 존재

네트워크 시작

cd fabric-samples/first-network
./byfn.sh up

네트워크 수정

1. crypto-config.yaml 수정

2. docker-compose-new-peer.yaml 작성

3. 암호자료 생성

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