Question

我正在尝试使用first-network中的fabric-samples创建一个应用程序通道。

我正在创建部署以运行在RAFT集群中运行的4个订购节点。以下是用于在configtx.yaml文件中创建Orderer Genesis块的配置文件部分。

SampleMultiNodeEtcdRaft
    <<: *ChannelDefaults
    Capabilities:
    <<: *ChannelCapabilities
    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: 8050
              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: 9050
              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: 10050
              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
        Addresses:
            - orderer.example.com:7050
            - orderer2.example.com:8050
            - orderer3.example.com:9050
            - orderer4.example.com:10050
        Organizations:
        - *OrdererOrg
        Capabilities:
            <<: *OrdererCapabilities
    Application:
        <<: *ApplicationDefaults
        Organizations:
        - <<: *OrdererOrg
    Consortiums:
        SampleConsortium:
            Organizations:
            - *Org1
            - *Org2

现在，我想创建一个仅具有3个订购节点（在给定4个订购节点中）的应用程序通道：orderer, orderer2, orderer3。因此，我将应用程序通道的配置文件部分设置如下（在configtx.yaml文件中）：

TwoOrgsChannel:
    Consortium: SampleConsortium
    <<: *ChannelDefaults
    Capabilities:
        <<: *ChannelCapabilities
    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: 8050
              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: 9050
              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
        Addresses:
            - orderer.example.com:7050
            - orderer2.example.com:8050
            - orderer3.example.com:9050
        Organizations:
            - *OrdererOrg
        Capabilities:
            <<: *OrdererCapabilities
    Application:
        <<: *ApplicationDefaults
        Organizations:
            - *Org1
            - *Org2
        Capabilities:
            <<: *ApplicationCapabilities

我正在使用默认的byfn.sh脚本来建立网络。

但是，当我尝试使用cli环境从orderer4容器中获取应用程序通道配置块时，我仍然能够成功实现并将其解码为JSON文件的功能，所有4个订购者都属于应用程序渠道的许可人部分，并且每个订购者的地址都位于订购者地址部分中。

那么，为什么只给前三个订购者作为同意者，申请渠道却不是仅从前三个订购者开始？

Answer 1

通道创建命令中必须包含-channelCreateTxBaseProfile自变量，并且该自变量的值将是订购者的创始简档名称（此处为SampleMultiNodeEtcdRaft）。

此外，尝试执行peer channel create命令的标识必须满足以下ACL：/Channel/Orderer/ConsensusType（默认情况下设置为以下策略：/Channel/Application/Admins）。

为RAFT应用程序频道设置订购者的子集
