0.8.990 verified Sat May 09 auth: no python

AWS CDK construct library (version 0.8.990) to deploy a Hyperledger Fabric network running on Amazon Managed Blockchain. Targeted at Python 3.9+ and follows a weekly release cadence.

pip install cdklabs-cdk-hyperledger-fabric-network

Common errors

error ModuleNotFoundError: No module named 'cdklabs' ↓

cause Missing dependency or wrong Python environment.

fix

pip install cdklabs-cdk-hyperledger-fabric-network

error ImportError: cannot import name 'HyperledgerFabricNetwork' from 'cdklabs' ↓

cause Incorrect import path; using base cdklabs package instead of submodule.

fix

Use from cdklabs.cdk_hyperledger_fabric_network import HyperledgerFabricNetwork

Warnings

breaking Version 0.8.x dropped support for NetworkVersion.V1_2; use V1_4 only. ↓

fix Set network_version=NetworkVersion.V1_4

gotcha Module import path uses underscores (cdk_hyperledger_fabric_network) not hyphens, but package name has hyphens. ↓

fix Use from cdklabs.cdk_hyperledger_fabric_network import ...

deprecated Property 'vpc' is deprecated in 0.7+; use 'vpc_config' instead. ↓

fix Use vpc_config=VpcConfig(...) (imported from same module)

Imports

HyperledgerFabricNetwork

from cdklabs.cdk_hyperledger_fabric_network import HyperledgerFabricNetwork

Use the dashed-to-underscore module naming

Quickstart

Deploy a basic Hyperledger Fabric network on Amazon Managed Blockchain. Replace key material with your own KMS key.

from aws_cdk import App, Stack
from aws_cdk import aws_kms as kms
from cdklabs.cdk_hyperledger_fabric_network import HyperledgerFabricNetwork, NetworkVersion

app = App()
stack = Stack(app, "TestStack")

HyperledgerFabricNetwork(
    stack,
    "MyNetwork",
    network_version=NetworkVersion.V1_4,
    member_name="Org1",
    key_material=kms.Key.from_lookup(stack, "Key", alias_name="alias/fabric-key"),
)

app.synth()
