[Blockchain 네트워크 구성] Chaincode instantiate / upgrade 시 “timeout expired” 오류 해결 방법

오류 파악

cli 컨테이너에서 체인코드를 설치하고 난 뒤, instantiate 또는 upgrade 명령을 수행했을 때 다음과 같은 오류가 발생하는 경우가 있습니다.

root@f2f9e3cad3e5:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode upgrade -o orderer.org1.honeybee.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/honeybee.com/orderers/orderer.org1.honeybee.com/msp/tlscacerts/tlsca.honeybee.com-cert.pem -C honeybeechannel -n tracecc -v 2.0 -c '{"Args":[""]}' -P "OR ('org1MSP.member','org2MSP.member','org3MSP.member','org4MSP.member','org5MSP.member','org6MSP.member')"

로그 확인

원인을 파악하기 위해 컨테이너들의 로그를 확인해봅니다.

orderer.org1.honeybee.com 컨테이너 로그 확인

orderer 컨테이너에는 명령을 수행하는 동안 별다른 로그가 나타나지 않았습니다.

peer0.org1.honeybee.com 컨테이너 로그 확인

peer0.org1.honeybee.com 컨테이너에서는 다음과 같은 두 가지 오류가 발생했습니다.

로그의 내용으로 보면 체인코드 상에 문제가 있는 것 같습니다.

오류 해결

체인코드 수정

우선, 체인코드에서 문제가 되는 부분을 수정해줍니다.

체인코드를 배포할 때에는 기본적으로 코드에 문제가 없는지 검증을 거친 후, 오류가 없을 경우에만 정상적으로 배포가 되는데 이 경우에는 체인코드에 문제가 있어서 배포가 정상적으로 이루어지지 않은 것으로 보입니다.

체인코드 재설치

체인코드 수정이 완료되면 버전을 변경해 모든 피어에 체인코드를 설치해줍니다.

여기에서는 해당 채널에 참여중인 12개의 피어에 모두 체인코드를 설치해 주었습니다.

체인코드 배포

설치가 완료되면 해당 체인코드에 대해 instantiate 또는 upgrade 명령을 실행합니다.

여기에서는 해당 체인코드가 이미 instantiate된 상태였기 때문에 upgrade 명령을 수행하였습니다.

peer chaincode upgrade -o orderer.org1.honeybee.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/honeybee.com/orderers/orderer.org1.honeybee.com/msp/tlscacerts/tlsca.honeybee.com-cert.pem -C honeybeechannel -n tracecc -v 3.0 -c '{"Args":[""]}' -P "OR ('org1MSP.member','org2MSP.member','org3MSP.member','org4MSP.member','org5MSP.member','org6MSP.member')"

peer chaincode list --instantiated -C honeybeechannel

다음과 같이 체인코드가 정상적으로 업그레이드된 것을 확인할 수 있습니다.
