# Hyperledger Fabric Network Generator
### This tool generates hyperledger fabric v1.x network related files to spwan a network quickly

Hyperledger Fabric Network Generator
--------------------------------------------
This is a simple tool to generate a set of scripts to spawn a docker-compose based hyperledger fabric network in a linux machine. Tool takes a simple JSON as input specifying any fabric network and generates a set of shell scripts, docker-compose.yaml file to start a network, create and join channels, install and update chain codes. Tool also generates a README file to assit new users with squence of scripts to runm in order to bring a hyperledger fabric network up and running.
The saves time for a developer to build a network without making any mistake in creating configtx.yaml, crypto-config.yaml. docker-compose files etc, those are required by a hyperledger fabric network to start.
Moreover this tools helps developers to concentrate more on the smart contract writing and developing other integration parts rather than concentrating on the infrastructure part. 
The future versions of this tool is aimed to support multi-vm , K8S complient and docker swarm compliant network configuration files and scripts generation.
