Kubernetes Test Network

This project re-establishes the Hyperledger test-network as a cloud native application.

Objectives:

• Provide a simple, one click activity for running the Fabric test network.
• Provide a reference guide for deploying production-style networks on Kubernetes.
• Provide a cloud ready platform for developing chaincode, Gateway, and blockchain apps.
• Provide a Kube supplement to the Fabric CA Operations and Deployment guides.
• Support a transition to Chaincode as a Service.
• Support a transition from the Internal, Docker daemon to External Chaincode builders.
• Run on any Kube.

Fabric, Ahoy!

Prerequisites

• Docker
• kubectl
• kind
• jq

Quickstart

Create a local Kubernetes cluster:

./network kind

Launch the network, create a channel, and deploy the basic-asset-transfer smart contract:

./network up
./network channel create
./network chaincode deploy

Invoke and query chaincode:

./network chaincode invoke '{"Args":["CreateAsset","1","blue","35","tom","1000"]}' 
./network chaincode query '{"Args":["ReadAsset","1"]}'

Access the blockchain with a REST API:

./network rest-easy

Tear down the test network:

./network down 

Tear down the cluster:

./network unkind

Areas for Improvement / TODOs

• Test the recipe with OCP, AWS, gcp, Azure, etc. (These should ONLY differ w.r.t. pvc and ingress)
• Implement @celder mechanism for bootstrapping dual-headed CAs w/o poisoning the root CA on expiry.
• Address any of the 20+ todo: notes in network.sh
• Implement mutual TLS across peers, orderers, and clients.
• Caliper?
