我正在尝试配置hyperledger结构网络。我跑了三个动物园管理员，三个kafkas，三个orderers和一个couchdb。它们是码头集装箱，运作良好。所有容器都位于名为ibknet的同一个docker网络中。之后，我运行peer容器但是在启动时检测couchdb容器有问题。这是我运行peer容器的命令。
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
以下是执行上述命令之前运行的docker容器的列表。

当我运行对等容器时，我在docker日志中收到此错误消息。

我错过了什么？我不知道75.126.101.240地址来自哪里。
实际上，我可以通过提到完全ip来成功运行--add-host选项。但我不认为这是一种正确的方式，因为每当我启动docker服务器时ip都会发生变化。
请帮助解决这个问题。谢谢。
尝试添加：“ - dns-search。”到docker run命令。主机系统上的解析程序可能配置为为未知主机追加/搜索域。 “--dns-search。”应该只通过嵌入式Docker DNS强制解析
