使用couchdb hyperledger结构时加入对等通道时出错

我正在使用一个简单的基本网络和两个对等点，并创建一个通道。这很好，但当我尝试添加coach db功能时，返回错误：

Channel created, joining Org1...
Error: error getting endorser client for channel: endorser client failed to connect to peer0.org1.example.com:7051: failed to create new connection: connection error: desc = "transport: error while dialing: dial tcp 172.22.0.5:7051: connect: connection refused"

只有在启用coach db时才会发生这种情况，如果没有couchdb，它将创建通道并将其连接到两个对等方

当我在没有couchdb的情况下启动容器时，我使用：

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

还有couchdb

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

docker-compose-coach.yaml包含：

version: '2'

  byfn:

services:
  couchdb0:
    container_name: couchdb0
    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.

    ports:
      - "5984:5984"

有什么想法吗？使用couchdb时是否存在连接错误的原因

谢谢

与对等方连接时似乎出现了一些问题，因此一旦网络中断，请删除所有容器和卷。然后重新开始网络设置

并尝试在这一次单独启动docker容器，即首先使用以下方法启动所有其他容器：

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

然后，启动couchdb容器，因为当couchdb启动并尝试搜索对等容器时，对等容器可能没有启动。因此，在所有其他容器用完后，请使用以下方法：

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

我也有同样的问题，我修正了它，在加入频道时增加了一点延迟

如果脚本在容器启动后创建并加入通道，则couchdb容器正在运行，但其中的数据库不在运行

---

在脚本中创建通道之前添加“sleep 2”解决了我的问题，以确保couchdb数据库已准备好为请求提供服务。

是的，这解决了我的问题。我查看了第一个网络示例，它有一个等待couchdb启动的函数，在连接3秒后重试三次后复制此函数。
