如何解决如何在 Kubernetes 设置中使用 Hyperledger Caliper 测量 Hyperledger Fabric 性能

我的结构网络部署在本地 Kubernetes 集群（vagrant）中，使用以下命令 https://medium.com/swlh/how-to-implement-hyperledger-fabric-external-chaincodes-within-a-kubernetes-cluster-fd01d7544523 教程。 Pod 已启动并正在运行，我能够从 fabric-cli 插入/读取弹珠。

我无法配置 caliper 来衡量我的部署性能。我在同一个“hyperledger”命名空间中运行了 caliper 0.4.2 docker 镜像。

caliper 部署 yaml 文件

我遵循了 https://hyperledger.github.io/caliper/v0.4.2/fabric-tutorial/tutorials-fabric-existing/ 有关在现有结构网络旁边运行 caliper 的文档。 networkconfig3.yaml 文件

name: Fabric
version: '2.0.0'
mutual-tls: true

caliper:
  blockchain: fabric
  sutOptions:
    mutualTls: true 

channels:
  - channelName: mychannel
    contracts:
    - id: marbles

organizations:
  - mspid: org1MSP
    identities:
      certificates:
      - name: 'Admin'
        admin: true
        clientPrivateKey:
          path: '../fabric-samples/crypto-config/peerOrganizations/org1/users/Admin@org1/msp/keystore/priv_sk'
        clientSignedCert:
          path: '../fabric-samples/crypto-config/peerOrganizations/org1/users/Admin@org1/msp/signcerts/Admin@org1-cert.pem'
      - name: 'User1'
        clientPrivateKey:
          path: '../fabric-samples/crypto-config/peerOrganizations/org1/users/User1@org1/msp/keystore/priv_sk'
        clientSignedCert:
          path: '../fabric-samples/crypto-config/peerOrganizations/org1/users/User1@org1/msp/signcerts/User1@org1-cert.pem'
    connectionProfile:
      path: 'networks/profile-org1.yaml'
      discover: true

org1 连接配置文件看起来像

name: Fabric
version: '1.0.0'

client:
  organization: org1
  connection:
    timeout:
      peer:
        endorser: '300'

organizations:
  org1:
    mspid: org1MSP
    peers:
    - peer0-org1

peers:
  peer0-org1:
    url: grpcs://peer0-org1:7051
    grpcOptions:
      ssl-target-name-override: peer0-org1
      grpc.keepalive_time_ms: 600000
    tlsCACerts:
      path: ../fabric-samples/crypto-config/peerOrganizations/org1/peers/peer0-org1/msp/tlscacerts/tlsca.org1-cert.pem

myAssetBenchmark.yaml 文件

test:
    name: marble-benchmark
    description: test benchmark
    workers:
      type: local
      number: 2
    rounds:
    - label: initMarble
      description: init marbles benchmark
      txNumber: 100
      rateControl:
        type: fixed-load
        opts:
          tps: 25
      workload:
        module: workload/init.js
monitor:
  type:
  - none

observer:
  type: local
  interval: 1

卡尺失败，因为与对等方的连接未通过。 2021-01-05T04:37:55.592Z - ^[[32minfo^[[39m: [NetworkConfig]: buildPeer - Unable to connect to the endorser peer0-org1 due to Error: Failed to connect before the deadline on Endorser- name: peer0-org1,url:grpcs://peer0-org1:7051,connected:false,connectAttempted:true

我当前的配置有什么问题？ 有没有什么博客或文档可以看更多？

解决方法

您的连接配置文件看起来不正确，因为您没有正确指定 tlsCACert 信息。由于您需要使用适用于节点 2.2 的连接配置文件，因此以下内容可能有效

name: Fabric

organizations:
  org1:
    mspid: org1MSP
    peers:
    - peer0-org1

peers:
  peer0-org1:
    url: grpcs://peer0-org1:7051
    tlsCACerts:
      path: ../fabric-samples/crypto-config/peerOrganizations/org1/peers/peer0-org1/msp/tlscacerts/tlsca.org1-cert.pem

这里有一些关于连接配置文件的 node sdk 2.2 预期格式的详细信息，但我不确定它们有多正确https://hyperledger.github.io/fabric-sdk-node/release-2.2/tutorial-commonconnectionprofile.html
