Fabric network interaction library (SDK wrapper), that contains its own network setup description format, network configuration utility, and convenience methods for working with Hyperledger Fabric.

All tools use fabric.yaml configuration file to get an overview of the Fabric network structure.

  • key-name – key value that can be used for referring orderer in this config file
    • url – url for access
    • pemFile – file location for x509 pem certificate for SSL
    • properties – list of orderer SDK properties

• channels – list of channels

  • key-name – key value that can be used for referring channel in application
    • admin – user that will be used for working with this channel
    • orderers – list of orderer key-names that serve this channel
    • peers – list of peer key-names that serve this channel
    • eventhubs (deprecated) – list of eventhub key-names that serve this channel

• cas – list of CAs

  • key-name – key value that can be used for referring CA in application
    • url – url for access
    • pemFile – file location for x509 pem certificate for SSL
    • allowAllHostNames – true/false, override certificates CN Host matching
    • adminLogin – login of CA admin user
    • adminSecret – secret of CA admin user
    • mspID – MSP identifier of organisation

Configurator

These fields are used to configure and update network config via fabric-configurator or NetworkManager's API:

• chaincodes – list of chaincodes

  • key-name – key value that can be used for referring chaincode in this config file
    • id – id of chaincode to be referenced by application
    • sourceLocation – path to chaincode, final path consist of ./{sourceLocationPrefix }/src/{sourceLocation}
    • sourceLocationPrefix – path prefix to chaincode
    • version – version number for this chaincode, should consist of v{number}
    • type – chaincode`s format\language
    • initArguments – list of arguments to for initialization function as JSON strings
    • collectionPolicy – object to describe collection policy (as specified in fabric-1.3 SDK)

• channels – list of channels

  • key-name – key value that can be used for referring channel in application
    • txFile – transaction file used for channel creation
    • chaincodes – list of chaincode key-names that should be deployed to this channel Might be in form of
      1. key [String]: reference to the chaincodes section
      2. object, which describes how to deploy this chaincode into that channel There are two keys currently recognized:
         • name: reference to the chaincodes section
         • collectionPolicy: object to describe collection policy (as specified in fabric-1.3 SDK) when collectionPolicy specified both in channels and in chaincodes sections, channels section takes precedence. collectionPolicy itself can be a string, referring to the yaml of json file, or an object to describe policy inline.

• users – list of users to enroll

  • key-name – key value that can be used for referring CA in which enroll users
    • userAffiliation – affiliation for users
    • list – user names
