使用 couchdb hyperledger fabric 时加入对等通道时出错

Question

我正在与两个对等方一起使用一个简单的基本网络，并创建一个通道。很好，但是当我尝试添加 couch db 功能时，returns 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 couch db 时才会发生这种情况，如果没有 couchdb，它会创建通道并将其加入两个对等点。

当我在没有 couchdb 的情况下启动容器时，我使用的是：

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-couch.yaml包含：

version: '2'

networks:
  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.
    environment:
      - COUCHDB_USER=
      - COUCHDB_PASSWORD=
    # Comment/Uncomment the port mapping if you want to hide/expose the CouchDB service,
    # for example map it to utilize Fauxton User Interface in dev environments.
    ports:
      - "5984:5984"
    networks:
      - byfn

  peer0.org1.example.com:
    environment:
      - CORE_LEDGER_STATE_STATEDATABASE=CouchDB
      - CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb0:5984
      # The CORE_LEDGER_STATE_COUCHDBCONFIG_USERNAME and CORE_LEDGER_STATE_COUCHDBCONFIG_PASSWORD
      # provide the credentials for ledger to connect to CouchDB.  The username and password must
      # match the username and password set for the associated CouchDB.
      - CORE_LEDGER_STATE_COUCHDBCONFIG_USERNAME=
      - CORE_LEDGER_STATE_COUCHDBCONFIG_PASSWORD=
    depends_on:
      - couchdb0


  couchdb1:
    container_name: couchdb1
    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=
    # Comment/Uncomment the port mapping if you want to hide/expose the CouchDB service,
    # for example map it to utilize Fauxton User Interface in dev environments.
    ports:
      - "7984:5984"
    networks:
      - byfn

  peer0.org2.example.com:
    environment:
      - CORE_LEDGER_STATE_STATEDATABASE=CouchDB
      - CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb1:5984
      # The CORE_LEDGER_STATE_COUCHDBCONFIG_USERNAME and CORE_LEDGER_STATE_COUCHDBCONFIG_PASSWORD
      # provide the credentials for ledger to connect to CouchDB.  The username and password must
      # match the username and password set for the associated CouchDB.
      - CORE_LEDGER_STATE_COUCHDBCONFIG_USERNAME=
      - CORE_LEDGER_STATE_COUCHDBCONFIG_PASSWORD=
    depends_on:
      - couchdb1

有什么想法吗？使用couchdb时有什么原因导致连接错误吗？

谢谢

似乎在与对等点连接时出现了一些问题，因此一旦网络中断，请删除所有容器和卷。然后再次开始网络设置。

这次尝试单独启动 docker 个容器，即首先使用以下命令启动所有其他容器：

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

然后，启动您的 couchdb 容器，因为当 couchdb 启动并尝试搜索对等容器时，您的对等容器可能未启动。所以在所有其他容器都启动之后使用这个：

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

我遇到了同样的问题，我修复了它，在加入频道时增加了一点延迟。

如果脚本在容器启动后立即创建并加入频道，则 couchdb 容器是运行而不是其中的数据库。

我的问题已解决，在我的脚本中创建通道之前添加 "sleep 2" 以确保 couchdb 数据库已准备好处理请求。
