部署链代码时出现连接错误

Question

我刚开始使用链码。

我正在一步一步地跟随：
http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#running-the-chaincode

我在Windows上使用Docker工具箱。

但是当我开始运行chaincode_example02时，我收到以下错误：

2016/09/15 14:05:53 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: dial tcp 0.0.0.0:7051: connectex: The requested address is not valid in its context."; Reconnecting to {"0.0.0.0:7051" <nil>}
2016/09/15 14:05:54 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: dial tcp 0.0.0.0:7051: connectex: The requested address is not valid in its context."; Reconnecting to {"0.0.0.0:7051" <nil>}
2016/09/15 14:05:55 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: dial tcp 0.0.0.0:7051: connectex: The requested address is not valid in its context."; Reconnecting to {"0.0.0.0:7051" <nil>}

为什么？
