錯誤啓動hyperledger fabcar示例應用程序

我試圖安裝從http://hyperledger-fabric.readthedocs.io/en/latest/write_first_app.html 錯誤啓動hyperledger fabcar示例應用程序

我得到類似的錯誤，以張貼在這裏提到的hyperledger織物樣本應用程序：hyperledger fabric fabcar error

2017-08-24 07:47:16.826 UTC [grpc] Printf -> DEBU 005 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: Error while dialing dial tcp 172.18.0.5:7051: getsockopt: connection refused"; Reconnecting to {peer0.org1.example.com:7051 <nil>} 
Error: Error getting endorser client channel: PER:404 - Error trying to connect to local peer

下面是日誌docker logs peer0.org1.example.com， apperantly peer無法連接到couchdb

我可以在端口上看到偵聽套接字5984

從搬運工EXEC - 它的CouchDB的bash 泊塢窗EXEC - 它的CouchDB的bash

從命令外殼沒有搬運工人

# netstat -ntulpa | grep 5984 
tcp6  0  0 :::5984     :::*     LISTEN  12877/docker-proxy

爲什麼對不能夠連接到CouchDB的？

如果你的主機上運行的「平CouchDB的」會發生什麼？ –

是的，我能ping通couchdb – Pras

這可能是問題所在。似乎您的主機已設置爲自動執行某種類型的DNS搜索並解析未知的主機名。將發佈一個可能的解決方案作爲 –

根據評論，我認爲您的主機系統配置爲使用自動解析未知主機名的DNS搜索域。您可能需要修改基本網絡/泊塢窗，compose.yml，並添加dns_search: .的配置價值，爲同行：
