configure confixtx.yaml file?

问题

I'm trying to build a Hyperledger Fabric network with the following

• Smartforce[Orderer Org]

  Falcon.io [ORG1]

  Frost.io [ORG2]

I have generated all cryptographic materials using cryptogen tool. now looking to build gensis block using configtxgen tool.

Here is configtx.yaml:

Profiles:
  TwoOrgOrdererGenesis:
    Orderer:
      <<: *OrdererDefaults
      Organizations:
        - *Smartforce

    Consortiums:
      SampleConsortium:
        Organizations:
          - *BusinessPartner1
          - *BusinessPartner2

  TwoOrgChannel:
    Consortium: SampleConsortium
    Application:
      <<: *ApplicationDefaults
      Organizations:
        - *BusinessPartner1
        - *BusinessPartner2

Organizations:
  - &Smartforce
    Name: smartforce
    ID: SmartforceMSP
    MSPDir: /home/falcon/iq-smartforce/crypto-config/ordererOrganizations/smartforce.io/msp

  - &BusinessPartner1
    Name: BusinessPartner1
    ID: FalconMSP
    MSPDir: /home/falcon/iq-smartforce/crypto-config/peerOrganizations/falcon.io/msp


  - &BusinessPartner2
    Name: BusinessPartner2
    ID: FrostMSP
    MSPDir: /home/frost/iq-smartforce/crypto-config/peerOrganizations/frost.io/msp


Orderer: &OrdererDefaults
  OrdererType: solo

  Addresses:
    - orderer.smartforce.io:7050

  BatchTimeout: 2s

  BatchSize:
    MaxMessageCount: 10
    AbsoluteMaxBytes: 99 MB
    PreferredMaxBytes: 512 KB

  Organizations:

Application: &ApplicationDefaults
  Organizations:

When I run the command :

configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

I get the following error:

回答1:

In YAML all anchors ( those tokens starting with &) need to precede any references to them (using aliases, the tokens starting with *) in the file.

So in the root-level mapping you should put your key Profiles and its value after the key Organizations, Orderer and Application (and their values):

Organizations:
  - &Smartforce
    Name: smartforce
    ID: SmartforceMSP
    MSPDir: /home/falcon/iq-smartforce/crypto-config/ordererOrganizations/smartforce.io/msp

  - &BusinessPartner1
    Name: BusinessPartner1
    ID: FalconMSP
    MSPDir: /home/falcon/iq-smartforce/crypto-config/peerOrganizations/falcon.io/msp

  - &BusinessPartner2
    Name: BusinessPartner2
    ID: FrostMSP
    MSPDir: /home/frost/iq-smartforce/crypto-config/peerOrganizations/frost.io/msp

Orderer: &OrdererDefaults
  OrdererType: solo

  Addresses:
    - orderer.smartforce.io:7050

  BatchTimeout: 2s

  BatchSize:
    MaxMessageCount: 10
    AbsoluteMaxBytes: 99 MB
    PreferredMaxBytes: 512 KB

  Organizations:

Application: &ApplicationDefaults
  Organizations:

Profiles:
  TwoOrgOrdererGenesis:
    Orderer:
      <<: *OrdererDefaults
      Organizations:
        - *Smartforce

    Consortiums:
      SampleConsortium:
        Organizations:
          - *BusinessPartner1
          - *BusinessPartner2

  TwoOrgChannel:
    Consortium: SampleConsortium
    Application:
      <<: *ApplicationDefaults
      Organizations:
        - *BusinessPartner1
        - *BusinessPartner2
