Hyperledger Fabric Network using Kubernetes

The objective of this post is to implement fabric network on Kubernetes platform.The indent is to explore the architecture behind kubernetes deployment of fabric network using a basic network .

We will deploy one master node , two worker nodes and a NFS server to share network artifacts and chain code data across the nodes.

Keeping it simple we will be deploying the Hyperledger Fabric network consisting of one organization, maintaining one peer node, one orderer with ‘solo’ ordering service. We will create a channel , join peer to the channel , install chaincode on peer and instantiate chaincode on channel. Also invoke transactions against the deployed chaincode.

Installation

Generate the Network Artifacts

Generate the network artifacts using configtx.yaml, crypto-config.yaml.If you intent to modify the network topology, change the configuration files (.yaml files) appropriately.

Copy (or use bind) the files from network artifacts , crypto and chaincode directory to NFS share.

Persistent Volume ( NFS)

Start the network

Now lets start the network by running scripts one by one.

Install ChainCode

Instantiate ChainCode

Invoke ChainCode

You would see that the chain code container is getting started inside the docker-dind pod as a sidecar container.
