hyperledger-fabric - 使用 CouchDB 启动第一个网络时出错

问题描述

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：超出上下文截止日期

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

标签： hyperledger-fabric

解决方案

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。

验证所有服务现在都指向使用 CouchDB，也许docker-compose-cli.yaml指向其他 DB 类型。

  peer0.org1.example.com:
container_name: peer0.org1.example.com

  couchdb:
    container_name: couchdb
    image: hyperledger/fabric-couchdb
    # Populate the COUCHDB_USER and COUCHDB_PASSWORD to set an admin user and password
    # for CouchDB.  This will prevent CouchDB from operating in an "Admin Party" mode.
    environment:
      - COUCHDB_USER=
      - COUCHDB_PASSWORD=
    ports:
      - 5984:5984
    networks:
      - basic

在示例中，您有一个对等服务和 couchDB 服务，您可以将其作为示例。

此外，我还有一个教程，介绍如何在基于 Fabric 示例的基本网络示例的多个主机中设置 Hyperledger Fabric。也许你可以作为参考。
