hyperledger-fabric - Chaincode 已实例化但未出现在实例化代码列表中

Question

我正在运行 Hyperledger Fabric 1.4.0

我有 1 个组织 (Org1)、2 个节点 (peer0、peer1) 和两个排序节点 (ord0 >，ord1)。对等方使用 couchdb 作为存储后端。

我能够成功地安装我的链代码，然后实例化它。

查看 peer0 日志，构建了 docker 镜像并启动了容器。 peer0 还接收并确认由容器内的 chaincode 二进制文件发送的 REGISTER 请求:

2019-06-24 10:15:57.182 UTC [chaincode] handleMessage -> DEBU b56f [1a98f442] Fabric side handling ChaincodeMessage of type: COMPLETED in state ready

尽管如此，链码并未在 couchdb 中注册:

$ peer chaincode list --instantiated -C mychannel
2019-06-24 11:26:29.317 BST [main] InitCmd -> WARN 001 CORE_LOGGING_LEVEL is no longer supported, please use the FABRIC_LOGGING_SPEC environment variable
2019-06-24 11:26:29.332 BST [main] SetOrdererEnv -> WARN 002 CORE_LOGGING_LEVEL is no longer supported, please use the FABRIC_LOGGING_SPEC environment variable
Get instantiated chaincodes on channel mychannel:

peer0 提交列表命令后立即记录:

2019-06-24 10:26:30.057 UTC [couchdb] ReadDocRange -> DEBU c02e [mychannel_lscc] HTTP/1.1 200 OK

如果我尝试调用链代码上的方法，我会收到此错误:

Error: endorsement failure during invoke. response: status:500 message:"make sure the chaincode mychain has been successfully instantiated and try again: chaincode mychain not found"

这只是确认链代码尚未在网络中注册。

更新

我意识到我错过了一个重要的细节:peer 日志反复报告连接到 orderer 的错误，例如:

2019-06-24 11:30:35.931 UTC [ConnProducer] NewConnection -> ERRO 100e6 Failed connecting to ord0.mynet.example.com , error: context deadline exceeded

这可能是“chaincode instantiated”消息没有传播的原因......

Answer 1

经过多次调试，发现问题很简单:节点无法与排序节点通信。

在我的特殊情况下，configtx.yaml 中的订购者地址是错误的。修复它们导致链代码实例化过程完全成功。
