Hyperledger_coffeeCirculationSystem

Management system about seed info using hyperledger fabric.

Introduction

The configuration is complete with distributors, shippers and cafes. Deploy amongst stakeholders more. Hyperledger Fabric. Better transparency can be managed. Server side development is for NodeJS, network can choose docker-compose.

Getting Start

After the process (requiremnet), you can see the directory structure

• Get keys of Orgs
  Command: ./generate.sh
  location : /fabricbook/network
  

• Check the keys of Orgs
  Command: ls crypto-config/peerOrganizations/org1.example.com/ca/ | grep _sk & ls crypto-config/peerOrganizations/org2.example.com/ca/ | grep _sk & ls crypto-config/peerOrganizations/org3.example.com/ca/ | grep _sk & ls crypto-config/peerOrganizations/org4.example.com/ca/ | grep _sk
  
  
  
  
  

• Mapping the keys with docker-compose
  
  
  This picture is docker-compose-template.yml. you must set the key for mapping with this. where you set is FABRIC_CA_SERVER_CA_KEYFILE in enviroment in ca1.example.com. than you update last strings at the strings(The strings contains sk. . than Do the same for each institution.
  
  

• set docker conatiner and make channel and join the channel
  
  
  This picture is that setting containers. If you want to check the works work good, Command "docker ps". This command show Currently working containers.
  
  This picture is finish about join

• Install Chaincode and Instatiate Chaincode at Orgs Command:
  ./cc.sh
  
  
  This picture is finish about that.

• How to join Org for users.

If you are importer, run "node server.js & node enrollment.js "
else if you are warehouse manager, run "node server2.js & node enrollment2.js "
else if you are roasting manager, run "node server3.js & node enrollment3.js "
else you are packing managerm run "node server4.js & node enrollment4.js"

After that, you have all connecting authority about each Organs.
