Fabric區塊鏈網絡運維工具configtxgen配置文件的示例分析

小編給大家分享一下Fabric區塊鏈網絡運維工具configtxgen配置文件的示例分析，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！

configtx.yaml是Hyperledger Fabric區塊鏈網絡運維工具configtxgen用于生成通道創世塊或通道交易的配置文件，configtx.yaml的內容直接決定了所生成的創世區塊的內容。

Capabilities / 通道能力配置

Capabilities段用來定義fabric網絡的能力。這是版本v1.0.0引入的一個新的配置段，當與版本v1.0.x的對等節點與排序節點混合組網時不可使用。

Capabilities段定義了fabric程序要加入網絡所必須支持的特性。例如，如果添加了一個新的MSP類型，那么更新的程序可能會根據該類型識別并驗證簽名，但是老版本的程序就沒有辦法驗證這些交易。這可能導致不同版本的fabric程序中維護的世界狀態不一致。

因此，通過定義通道的能力，就明確了不滿足該能力要求的fabric程序，將無法處理交易，除非升級到新的版本。對于v1.0.x的程序而言，如果在Capabilities段定義了任何能力，即使聲明不需要支持這些能力，都會導致其有意崩潰。

Capabilities:
    # Global配置同時應用于排序節點和對等節點，并且必須被兩種節點同時支持。
    # 將該配置項設置為ture表明要求節點具備該能力
    Global: &ChannelCapabilities
        V1_3: true

    # Orderer配置僅應用于排序節點，不需考慮對等節點的升級。將該配置項
    # 設置為true表明要求排序節點具備該能力
    Orderer: &OrdererCapabilities
        V1_1: true

    # Application配置僅應用于對等網絡，不需考慮排序節點的升級。將該配置項
    # 設置為true表明要求對等節點具備該能力
    Application: &ApplicationCapabilities
        V1_3: true

Organizations / 組織機構配置

Organizations配置段用來定義組織機構實體，以便在后續配置中引用。例如，下面的配置文件中，定義了三個機構，可以分別使用ExampleCom、Org1ExampleCom和Org2ExampleCom引用其配置：

Organizations:

    - &ExampleCom
        Name: ExampleCom
        ID: example.com
        AdminPrincipal: Role.ADMIN
        MSPDir: ./ordererOrganizations/example.com/msp
        Policies:
            Readers:
                Type: Signature
                Rule: OR('example.com.member')
            Writers:
                Type: Signature
                Rule: OR('example.com.member')
            Admins:
                Type: Signature
                Rule: OR('example.com.admin')
            Endorsement:
                Type: Signature
                Rule: OR('example.com.member')

    - &Org1ExampleCom
        Name: Org1ExampleCom
        ID: org1.example.com
        MSPDir: ./peerOrganizations/org1.example.com/msp
        AdminPrincipal: Role.ADMIN
        AnchorPeers:
            - Host: peer0.org1.example.com
              Port: 7051
        Policies:
            Readers:
                Type: Signature
                Rule: OR('org1.example.com.member')
            Writers:
                Type: Signature
                Rule: OR('org1.example.com.member')
            Admins:
                Type: Signature
                Rule: OR('org1.example.com.admin')
            Endorsement:
                Type: Signature
                Rule: OR('org1.example.com.member')

    - &Org2ExampleCom
        Name: Org2ExampleCom
        ID: org2.example.com
        MSPDir: ./peerOrganizations/org2.example.com/msp
        AdminPrincipal: Role.ADMIN
        AnchorPeers:
            - Host: peer0.org2.example.com
              Port: 7051
        Policies:
            Readers:
                Type: Signature
                Rule: OR('org2.example.com.member')
            Writers:
                Type: Signature
                Rule: OR('org2.example.com.member')
            Admins:
                Type: Signature
                Rule: OR('org2.example.com.admin')
            Endorsement:
                Type: Signature
                Rule: OR('org2.example.com.member')

Orderer / 排序節點配置

Orderer配置段用來定義要編碼寫入創世區塊或通道交易的排序節點參數。

Orderer: &OrdererDefaults

    # 排序節點類型用來指定要啟用的排序節點實現，不同的實現對應不同的共識算法。
    # 目前可用的類型為：solo和kafka
    OrdererType: solo
    Addresses:
        - orderer0.example.com:7050

    # Capabilities配置描述排序節點層級的能力需求，這里直接引用
    # 前面Capabilities配置段中的OrdererCapabilities配置項
    Capabilities:

Channel / 通道配置

Channel配置段用來定義要寫入創世區塊或配置交易的通道參數。

Channel: &ChannelDefaults
    # 定義本層級的通道訪問策略，其權威路徑為 /Channel/<PolicyName>
    Policies:
        Readers:
            Type: ImplicitMeta
            Rule: ANY Readers
        # Writes策略定義了調用Broadcast API提交交易的許可規則
        Writers:
            Type: ImplicitMeta
            Rule: ANY Writers
        # Admin策略定義了修改本層級配置的許可規則

Application / 應用配置

Application配置段用來定義要寫入創世區塊或配置交易的應用參數。

Application: &ApplicationDefaults
    ACLs: &ACLsDefault
        # ACLs配置段為系統中各種資源提供默認的策略。
        # 這里所說的“資源”，可以是系統鏈碼的函數，例如qscc系統鏈碼的GetBlockByNumber方法
        # 也可以是其他資源，例如誰可以接收區塊事件。
        # 這個配置段不是用來定義資源或API，而僅僅是定義資源的訪問控制策略
        # 
        # 用戶可以在通道定義中重寫這些默認策略

Profiles / 配置入口

Profiles配置段用來定義用于configtxgen工具的配置入口。包含委員會（consortium）的配置入口可以用來生成排序節點的創世區塊。如果在排序節點的創世區塊中正確定義了consortium的成員，那么可以僅使用機構成員名稱和委員會的名稱來生成通道創建請求。
