Hyperledger Fabric对等容器无法与Couchdb容器通信 [英] Hyperledger Fabric peer container cannot communicate with couchdb container
问题描述
我正在尝试配置超级账本结构网络. 我经营着三名动物园管理员，三名kafkas，三名定购者和一个couchdb. 它们是docker容器，运作良好.所有容器都在同一个称为ibknet的docker网络中. 在那之后，我运行对等容器，但是在启动它时无法检测到couchdb容器.这是我运行对等容器的命令.
I am trying to configure hyperledger fabric network. I run three zookeepers, three kafkas, three orderers and a couchdb. They are docker containers and work well. All containers are in the same docker network called ibknet. After that, I run peer container but it has a problem to detect couchdb container while its starting. Here is my command to run peer container.
docker run -d --name main.stock.ibk.com --hostname main.stock.ibk.com \
-p 7051:7051 \
-p 7053:7053 \
-e CORE_LEDGER_STATE_STATEDATABASE=CouchDB \
-e CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb0:5984 \
--network ibknet hyperledger/fabric-peer:x86_64-1.0.4
docker run -d --name main.stock.ibk.com --hostname main.stock.ibk.com \
-p 7051:7051 \
-p 7053:7053 \
-e CORE_LEDGER_STATE_STATEDATABASE=CouchDB \
-e CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb0:5984 \
--network ibknet hyperledger/fabric-peer:x86_64-1.0.4
这是在执行上述命令之前正在运行的Docker容器的列表.
Here is the list of running docker containers before executing the command above.

当我运行对等容器时，我在docker日志中收到了此错误消息.
And I got this error messages in docker logs when I run the peer container.

我想念什么?而且我不知道75.126.101.240的地址是哪里.
What do I miss? And I have no idea that where 75.126.101.240 address is from.
实际上，我可以通过--add-host选项成功运行它，只需提及确切的ip.但是我认为这不是正确的方法，因为每当我启动docker服务器时ip都会发生变化.
Actually, I could succeed in running it with --add-host option by mentioning exactly ip. But I don't think that is a proper way because ip is changing whenever I start docker servers.
请帮助解决此问题.谢谢.
Please help this issue. Thanks.
推荐答案
尝试添加:"--dns-search".到docker run命令.主机系统上的解析器可能已配置为在域中附加/搜索未知主机. "--dns-search."应该仅通过嵌入式Docker DNS强制进行解析
Try adding : "--dns-search ." to the docker run command. The resolver on your host system is likely configured to append / search a domain for unknown hosts. "--dns-search ." should force resolution only via the embedded Docker DNS
