使用 CouchDB 启动第一个网络时出错

Question

将对等方加入频道时出现以下错误：-

错误：获取通道的背书客户端时出错：背书客户端无法连接到 peer0.org1.example.com:7051：无法创建新连接：超出上下文期限

请注意：-

我用过 CouchDb。编写以下命令：-

docker-compose -f docker-compose-cli.yaml -f docker-compose-couch.yaml up -d

Answer 1

也许你可以对 docker-compose-couch.yaml 和你的旧文件进行一些验证，我假设你替换它但文件仍然存在。

现在验证所有服务都指向使用 CouchDB，也许 docker-compose-cli.yaml 指向另一个 DB 类型。

  peer0.org1.example.com:

    # Populate the COUCHDB_USER and COUCHDB_PASSWORD to set an admin user and password

在示例中你有一个peer服务和couchDB服务，你可以以它为例。

此外，我还有一个教程，介绍了如何根据 Fabric 示例的基本网络示例在多个主机中设置 Hyperledger Fabric。或许你可以参考一下。
