Hyperledger-fabric:链码部署连接错误

我正在尝试使用docker测试fabric chaincode example02。我是新手:)

这是我的docker-compose.yml

membersrvc:
  image: hyperledger/fabric-membersrvc
  command: membersrvc

vp0:
  image: hyperledger/fabric-peer
  environment:
    - CORE_PER_ID=vp0
    - CORE_PEER_ADDRESSAUTODETECT=true
    - CORE_VM_ENDPOINT=http://0.0.0.0:2375
    - CORE_LOGGING_LEVEL=DEBUG
  command: sh -c "sleep 5; peer node start --peer-chaincodedev"

vp1:
  extends:
    service: vp0
  environment:
    - CORE_PEER_ID=vp1
    - CORE_PEER_DISCOVERY_ROOTNODE=vp0:7051
  links:
    - vp0

vp2:
  extends:
    service: vp0
  environment:
    - CORE_PEER_ID=vp2
    - CORE_PEER_DISCOVERY_ROOTNODE=vp0:7051
  links:
    - vp0

我跑(我指的是Fabric chaincode setup page):

1号航站楼:

$ docker-compose up

2号航站楼:

$ cd /hyperledger/examples/chaincode/go/chaincode_example02

$ CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=0.0.0.0:7051 ./chaincode_example02

3号航站楼:

$ peer chaincode deploy -n mycc -c '{"Args": ["init", "a","100", "b", "200"]}'

它在终端1,2中运行良好。但终端3显示连接错误。

2016/10/21 04:39:15 grpc: addrConn.resetTransport failed to create client
transport: connection error: desc = "transport: dial tcp 0.0.0.0:7051:
getsockopt: connection refused"; Reconnecting to {"0.0.0.0:7051" <nil>}
Error: Error building chaincode: Error trying to connect to local peer: 
grpc: timed out when dialing

有什么问题?

1 个答案:

答案 0 :(得分:3)

似乎你缺少compose语句来将所需的端口从docker容器映射到主机(你正在尝试peer命令)。因此,对等进程可能正在侦听对等端口容器内的端口7051,但此连接不可用于终端3中此容器外部使用的对等命令。

您可以使用&#39;端口&#39;来映射端口。标签。例如:

membersrvc:
  image: hyperledger/fabric-membersrvc
  ports:
    - "7054:7054"
  command: membersrvc

vp0:
  image: hyperledger/fabric-peer
  ports:
    - "7050:7050"
    - "7051:7051"
    - "7053:7053"
  environment:
    - CORE_PER_ID=vp0
    - CORE_PEER_ADDRESSAUTODETECT=true
    - CORE_VM_ENDPOINT=http://0.0.0.0:2375
    - CORE_LOGGING_LEVEL=DEBUG
  command: sh -c "sleep 5; peer node start --peer-chaincodedev"

在终端3中执行peer chaincode deploy ...之前,您可以使用

检查对等进程是否正在侦听端口7051
netstat -lnptu |grep 7051
