使用Hyperledger Fabric添加自定义节点OU

Question

我正在尝试在configtx.yaml文件内的策略定义中添加自定义节点OU。策略定义出现在configtx.yaml文件的“应用程序”部分中，如下所示：

Application: &ApplicationDefaults

# Organizations is the list of orgs which are defined as participants on
# the application side of the network
ACLs: &ACLsDefault
    peer/Propose: /Channel/Application/Checkous

Organizations:

# Policies defines the set of policies at this level of the config tree
# For Application policies, their canonical path is
#   /Channel/Application/<PolicyName>
Policies:
    Readers:
        Type: ImplicitMeta
        Rule: "ANY Readers"
    Writers:
        Type: ImplicitMeta
        Rule: "ANY Writers"
    Admins:
        Type: ImplicitMeta
        Rule: "MAJORITY Admins"
    Checkous:
        Type: Signature
        Rule: "OR('Org1MSP.admin', 'Org1MSP.client', 'Org1MSP.dept')"

Capabilities:
    <<: *ApplicationCapabilities

我已经使用cryptogen工具生成了加密材料。如您所见，我也在其中一个ACL中使用自定义策略。

接下来，我创建了订单生成块。

随后，当我尝试创建通道配置块时，收到以下错误：

注意：我已经在~/fabric-samples/first-network/crypto-config/peerOrganizations/org1.example.com/msp的config.yaml文件中添加了此OU的定义。该文件如下所示：

NodeOUs:
  Enable: true
  ClientOUIdentifier:
    Certificate: cacerts/ca.org1.example.com-cert.pem
    OrganizationalUnitIdentifier: client
  PeerOUIdentifier:
    Certificate: cacerts/ca.org1.example.com-cert.pem
    OrganizationalUnitIdentifier: peer
  AdminOUIdentifier:
    Certificate: cacerts/ca.org1.example.com-cert.pem
    OrganizationalUnitIdentifier: admin
  OrdererOUIdentifier:
    Certificate: cacerts/ca.org1.example.com-cert.pem
    OrganizationalUnitIdentifier: orderer
  DeptOUIdentifier:
    Certificate: cacerts/ca.org1.example.com-cert.pem
    OrganizationalUnitIdentifier: dept

1. 上述通道块创建中的错误是什么意思，以及解决该错误的任何解决方案？
2. 如何使用Fabric CA（而不是密码原）在网络中使用自定义节点OU？

Answer 1

您不能使用“自定义” NodeOU标识符。结构策略仅支持以下角色：

• $ MSPID.admin
• $ MSPID.member
• $ MSPID.peer
• $ MSPID.client
• $ MSPID.orderer

这意味着您只能使用内置的节点OU标识符：

• ClientOUIdentifier
• PeerOUIdentifier
• AdminOUIdentifier
• OrdererOUIdentifier
