configtx.yaml中文注解 原

configtx.yaml是Hyperledger Fabric区块链网络运维工具configtxgen用于生成通道创世块或通道交易的配置文件,configtx.yaml的内容直接决定了所生成的创世区块的内容。本文将给出configtx.yaml的详细中文说明。

Capabilities / 通道能力配置

Capabilities段用来定义fabric网络的能力。这是版本v1.0.0引入的一个新的配置段,当与版本v1.0.x的对等节点与排序节点混合组网时不可使用。

Capabilities段定义了fabric程序要加入网络所必须支持的特性。例如,如果添加了一个新的MSP类型,那么更新的程序可能会根据该类型识别并验证签名,但是老版本的程序就没有办法验证这些交易。这可能导致不同版本的fabric程序中维护的世界状态不一致。

因此,通过定义通道的能力,就明确了不满足该能力要求的fabric程序,将无法处理交易,除非升级到新的版本。对于v1.0.x的程序而言,如果在Capabilities段定义了任何能力,即使声明不需要支持这些能力,都会导致其有意崩溃。

Capabilities:
    # Global配置同时应用于排序节点和对等节点,并且必须被两种节点同时支持。
    # 将该配置项设置为ture表明要求节点具备该能力
    Global: &ChannelCapabilities
        V1_3: true

    # Orderer配置仅应用于排序节点,不需考虑对等节点的升级。将该配置项
    # 设置为true表明要求排序节点具备该能力
    Orderer: &OrdererCapabilities
        V1_1: true

    # Application配置仅应用于对等网络,不需考虑排序节点的升级。将该配置项
    # 设置为true表明要求对等节点具备该能力
    Application: &ApplicationCapabilities
        V1_3: true

Organizations / 组织机构配置

Organizations配置段用来定义组织机构实体,以便在后续配置中引用。例如,下面的配置文件中,定义了三个机构,可以分别使用ExampleCom、Org1ExampleCom和Org2ExampleCom引用其配置:

Organizations:

    - &ExampleCom
        Name: ExampleCom
        ID: example.com
        AdminPrincipal: Role.ADMIN
        MSPDir: ./ordererOrganizations/example.com/msp

        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:

                Rule: OR('org2.example.com.member')

Orderer / 排序节点配置

        # 也可以是其他资源,例如谁可以接收区块事件。
        # 这个配置段不是用来定义资源或API,而仅仅是定义资源的访问控制策略

Profiles / 配置入口

Profiles配置段用来定义用于configtxgen工具的配置入口。包含委员会(consortium)的配置入口可以用来生成排序节点的创世区块。如果在排序节点的创世区块中正确定义了consortium的成员,那么可以仅使用机构成员名称和委员会的名称来生成通道创建请求。
