[blockchain-explorer] Fabric v1.4.6 byfn 네트워크에 Docker로 blockchain-explorer 실행

Github : https://github.com/hyperledger/blockchain-explorer

 

소스 코드 복제

# 소스 코드 복제
cd /opt/gopath/src/github.com/hyperledger/
git clone https://github.com/hyperledger/blockchain-explorer
cd blockchain-explorer

 

실행 환경 설정

docker-compose.yaml 파일 수정

# docker-compose.yaml 파일 수정
vi docker-compose.yaml

explorer.mynetwork.com 서비스의 볼륨 설정을 변경해줘야합니다.

byfn 네트워크 실행 시 만들어진 crypto-config 디렉토리를 ./examples/net1/crypto 디렉토리로 복사하거나, 해당 디렉토리로 볼륨을 설정해주어야 합니다.
여기서는 볼륨 경로를 수정하겠습니다.

  explorer.mynetwork.com:
...
   volumes:
...
      - /opt/gopath/src/github.com/hyperledger/fabric-samples/first-network/crypto-config:/tmp/crypto
...

※ byfn의 네트워크 이름은 net_byfn으로 설정되어있기 때문에 networks > mynetwork.com > external > name은 'net_byfn'으로 설정합니다.

만약, byfn 네트워크가 아닌 커스텀 네트워크로 띄웠다면 name을 수정해주어야 합니다.
네트워크는 다음 명령으로 확인 가능합니다.

# Docker 네트워크 확인
docker network ls

 

examples/net1/config.json 파일 수정

이 부분은 별다른 변경 사항이 없기 때문에 생략합니다.
만약, 네트워크의 이름(default: first-network)이나 profile 설정 파일을 변경하고 싶은 경우에는 수정이 필요합니다.

# examples/net1/config.json 파일 수정
vi examples/net1/config.json

 

examples/net1/connection-profile/first-network.json 파일 수정

# examples/net1/connection-profile/first-network.json 파일 수정
vi examples/net1/connection-profile/first-network.json

이곳에서는 채널 이름과 peers, organizations에 대한 항목 추가/수정이 필요합니다.
자신이 생성한 채널 이름에 맞게 설정해주어야 오류가 나지 않습니다.

또한, Org의 adminPrivateKey > path도 자신의 crypto-config 디렉토리 내에 있는 실제 _sk 값으로 변경해주어야 합니다.

blockchain-explorer 실행/종료

blockchain-explorer 실행

이제 모든 설정이 끝났으면, blockchain-explorer를 실행합니다.

# blockchain-explorer 실행
cd /opt/gopath/src/github.com/hyperledger/blockchain-explorer
docker-compose up -d
docker container ls -a

※ docker-compose.yaml 파일에는 Prometheus와 Grafana 서비스도 정의되어있기 때문에, Prometheus와 Grafana 컨테이너도 함께 실행됩니다.

blockchain-explorer 종료

blockchain-explorer를 종료할 때에는 -v 옵션을 추가해 Docker 볼륨까지 제거합니다.

# blockchain-explorer 종료
cd /opt/gopath/src/github.com/hyperledger/blockchain-explorer
docker-compose down -v
