关于Raft共识配置的问题

Questions about Raft consensus configuration

我对 Hyperledger Fabric 1.41 上的 raft 配置有疑问,为什么在 configtx.yaml 文件中将所有 raft 排序器配置为侦听 7050 端口,但是在 docker-compose 文件中所有订购者正在收听 7050、8050、9050 等?这是如何工作的?

Configtx.yaml

 Orderer:
            <<: *OrdererDefaults
            OrdererType: etcdraft
            EtcdRaft:
                Consenters:
                - Host: orderer.example.com
                  Port: 7050
                  ClientTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/server.crt
                  ServerTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/server.crt
                - Host: orderer2.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 connection.json 应该更新,包括所有订购者及其端口,对吗?

所有排序节点都在监听容器的 7050 端口。

下面的代码将主机的端口映射到容器,因此您的主机在 9050 上接收时会将流量重定向到容器的 7050 端口。

ports:
- 9050:7050

因为同一个docker compose 中的容器可以通过容器端口相互访问。

此 9050、8050 仅在您需要从外部联系它们时才有用 docker-compose。
