关于Raft共识配置的问题

Question

我对Hyperledger Fabric 1.41上的筏配置有疑问，为什么在configtx.yaml文件上将所有筏订购者配置为侦听7050端口，但是在docker-compose文件中，所有订购者都在侦听7050、8050、9050等？ 如何运作？

Configtx.yaml

 Orderer:
            <<: *OrdererDefaults
            OrdererType: etcdraft
            EtcdRaft:
                Consenters:
                - Host: orderer.example.com
                  Port: 7050

                  ClientTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer2.example.com/tls/server.crt
                  ServerTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer2.example.com/tls/server.crt
                - Host: orderer3.example.com
                  Port: 7050
                  ClientTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer3.example.com/tls/server.crt
                  ServerTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer3.example.com/tls/server.crt
                - Host: orderer4.example.com
                  Port: 7050
                  ClientTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer4.example.com/tls/server.crt
                  ServerTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer4.example.com/tls/server.crt
                - Host: orderer5.example.com
                  Port: 7050
                  ClientTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer5.example.com/tls/server.crt
                  ServerTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer5.example.com/tls/server.crt
            Addresses:
                - orderer.example.com:7050
                - orderer2.example.com:7050
                - orderer3.example.com:7050
                - orderer4.example.com:7050
                - orderer5.example.com:7050

Docker-compose-etcdraft2.yaml（例如orderer3部分）

  orderer3.example.com:
    extends:
      file: base/peer-base.yaml
      service: orderer-base
    container_name: orderer3.example.com
    networks:
    - byfn
    volumes:
        - ./channel-artifacts/genesis.block:/var/hyperledger/orderer/orderer.genesis.block
        - ./crypto-config/ordererOrganizations/example.com/orderers/orderer3.example.com/msp:/var/hyperledger/orderer/msp
        - ./crypto-config/ordererOrganizations/example.com/orderers/orderer3.example.com/tls/:/var/hyperledger/orderer/tls
        - orderer3.example.com:/var/hyperledger/production/orderer
    ports:
    - 9050:7050

按照相同的模式，我认为应该更新connection.json，包括所有带有端口的订购者，对吗？

Answer 1

所有订购者都在监听容器的端口7050。

下面的代码将主机的端口映射到容器，因此当在9050上接收时，主机会将流量重定向到容器7050的端口。

ports:
- 9050:7050

这是因为同一docker内部的容器可以通过使用容器端口相互访问。

仅当您需要从docker-compose外部访问它们时，此9050、8050才有用。
