docker - Hyperledger Fabric 对等容器无法与 couchdb 容器通信

Question

我正在尝试配置 hyperledger fabric 网络。我经营着三个动物园管理员、三个卡夫卡、三个订购者和一个 couchdb。它们是 docker 容器并且运行良好。所有容器都在同一个名为 ibknet 的 docker 网络中。之后，我运行 peer container 但它在启动时检测 couchdb 容器时遇到问题。这是我运行对等容器的命令。

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

这是执行上述命令之前正在运行的 docker 容器的列表。

当我运行对等容器时，我在 docker 日志中收到了这个错误消息。

我错过了什么？我不知道 75.126.101.240 地址来自哪里。

实际上，我可以通过准确地提及 ip 来使用 --add-host 选项成功运行它。但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。

请帮忙解决这个问题。谢谢。

尝试添加:“--dns-search。”到 docker run 命令。您主机系统上的解析器可能配置为附加/搜索未知主机的域。 “--dns 搜索。”应该只通过嵌入式 Docker DNS 强制解析
