cdk-hyperledger-fabric-network

Hyperledger Fabric on Amazon Managed Blockchain

This repository contains an L2 CDK construct to deploy a Hyperledger Fabric network running on Amazon Managed Blockchain. It currently builds out a member and its nodes, but the following enhanced functionality is planned for future releases:

• Add support for Java and .NET
• Enroll users, storing their credentials in Secrets Manager
• Create channels on nodes
• Instantiate chaincode on nodes
• Set up a VPC and associated endpoint for accessing the network

Installation

The construct is available for both TypeScript and Python CDK projects. It can be installed with the following:

• TypeScript: npm install --save cdk-hyperledger-fabric-network
• Python: pip3 install cdk-hyperledger-fabric-network

Note that this construct requires AWS CDK v2.

Usage

A minimally complete deployment is shown below. By default, a standard network will be created running Hyperledger Fabric 1.4 with a single bc.t3.small node.

import { Stack, StackProps } from 'aws-cdk-lib';
import { Construct } from 'constructs';
import { HyperledgerFabricNetwork } from 'cdk-hyperledger-fabric-network';

class MyStack extends Stack {
  constructor(scope: Construct, id: string, props?: StackProps) {
    super(scope, id, props);
    new HyperledgerFabricNetwork(this, 'Example', {
      networkName: 'MyNetwork',
      memberName: 'MyMember',
    });
  });
}

The equivalent Python code is as follows:

from aws_cdk import Stack
from cdk_hyperledger_fabric_network import HyperledgerFabricNetwork

class MyStack(Stack):
    def __init__(self, scope, id, **kwargs):
        super().__init__(scope, id, **kwargs)
        HyperledgerFabricNetwork(
            self, 'Example',
            network_name='MyNetwork',
            member_name='MyMember',
        )

The following is a more complex instantiation illustrating some of the options available.

new HyperledgerFabricNetwork(this, 'Example', {
  networkName: 'MyNetwork',
  networkDescription: 'This is my Hyperledger Fabric network',
  memberName: 'MyMember',
  networkDescription: 'This is my Hyperledger Fabric member',
  frameworkVersion: hyperledger.FrameworkVersion.VERSION_1_2,
  proposalDurationInHours: 48,
  thresholdPercentage: 75,
  nodes: [
    {
      availabilityZone: 'us-east-1a',
      instanceType: hyperledger.InstanceType.STANDARD5_LARGE,
    },
    {
      availabilityZone: 'us-east-1b',
      instanceType: hyperledger.InstanceType.STANDARD5_LARGE,
    },
  ],
});
