node.js - 容器化区块链微服务

问题描述

如果我在主机上托管我的微服务，它会按预期工作，但如果我在容器中托管相同的东西，我会收到以下错误：

解决方案

在此处的输出中，您可以看到

2020-09-27T08:35:15.119Z - error: [DiscoveryService]: _buildPeer[blockit] - Unable to connect to the discovered peer peer1.blockit.co:8051 due to Error: Failed to connect before the deadline on Endorser- name: peer1.blockit.co:8051, url:grpcs://localhost:8051, connected:false, connectAttempted:true

它正在尝试连接到 localhost:8051。当 localhost 解析为您在其中运行应用程序的容器时，它不会找到它。您可能正在解析为 localhost 因为您已asLocalHost为您的应用程序设置为 true 您需要将此选项设置为 false 并确保您所在容器中的应用程序可以解析为您定义的预期主机名
