无法注册链码并成功启动区块链网络

Question

我正在遵循hyperledger fabric教程，注册我的链码并可能启动docker图像时遇到问题：https://www.ibm.com/developerworks/library/j-chaincode-for-java-developers/

以下是我尝试注册链码时遇到的错误：

$ ./Example

May 10, 2017 9:40:36 PM org.hyperledger.java.shim.ChaincodeBase$1 onError
SEVERE: Unable to connect to peer server: UNAVAILABLE

我通过docker的区块链网络已启动并运行，但最后一条日志消息与预期的日志消息不同(它显示连接到：[]，我假设它为空)：

05:47:30.205 [peer] chatWithSomePeers -> DEBU 02f Starting up the first peer of a new network

05:47:36.209 [peer] ensureConnected -> DEBU 038 Discovery knows about: []

当我检查正在运行docker的容器时，显示它们都在运行，如下所示：

CONTAINER ID        IMAGE                           COMMAND                  CREATED             STATUS              PORTS                                                      NAMES

使用了以下git命令: git clone https://github.com/hyperledger/fabric.git -b v0.6

我复制并粘贴了docker-compose.yml的精确值，如下所示：

membersrvc:
  image: hyperledger/fabric-membersrvc
  ports:
    - "7054:7054"
  command: membersrvc
vp0:
  image: hyperledger/fabric-peer
  ports:
    - "7050:7050"
    - "7051:7051"
    - "7053:7053"
  environment:
    - CORE_PEER_ADDRESSAUTODETECT=true
    - CORE_VM_ENDPOINT=unix:///var/run/docker.sock
    - CORE_LOGGING_LEVEL=DEBUG
    - CORE_PEER_ID=vp0
    - CORE_PEER_PKI_ECA_PADDR=membersrvc:7054
    - CORE_PEER_PKI_TCA_PADDR=membersrvc:7054
    - CORE_PEER_PKI_TLSCA_PADDR=membersrvc:7054
    - CORE_SECURITY_ENABLED=false
    - CORE_SECURITY_ENROLLID=test_vp0
    - CORE_SECURITY_ENROLLSECRET=MwYpmSRjupbT
  links:
    - membersrvc
  command: sh -c "sleep 5; peer node start --peer-chaincodedev"

我是不是漏掉了什么？感谢您的帮助，谢谢。

您似乎是在Windows环境下工作，除了没有定义任何端口转发到Oracle VM虚拟盒之外，一切都做得很正确。您必须配置Oracle VM VirtualBox Manager -> Setting -> Network -> Advance -> port forwarding --并根据附加的映像定义运行和享受...enter image description here

祝你编码愉快！
