我正在关注Hyperledger Fabric教程，但无法注册我的链码并可能无法启动Docker镜像:
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

我通过docker的区块链网络已启动并正在运行，但是最后一条日志消息与预期的日志消息不同(它显示Connected to:[]，我认为是null):

当我检查正在运行的Docker的容器时，我都将它们都打开了，请参见下文:

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的确切值，请参见下文:

我在这里缺少什么吗？任何帮助表示赞赏，谢谢。
最佳答案
似乎您在Windows环境中工作，并且除未定义将任何端口转发到Oracle VM虚拟框中外，其他所有操作都正确。您将需要配置
Oracle VM VirtualBox Manager->设置->网络->高级->端口转发-并根据附加的镜像进行定义，运行并享受...。enter image description here
编码愉快!
