Following are the software dependencies required.

Quick start (using Docker)

Prerequisites

• Docker
• Docker Compose

Start Hyperledger Fabric network

In this guide, we assume that you've already started test network by following Hyperledger Fabric official tutorial.

Configure

• Copy the following files from repository

  • docker-compose.yaml
  • examples/artifacts/network-config.yaml

  $ wget https://raw.githubusercontent.com/Akachain/akc-admin/master/example/artifacts/network-config.yaml
  $ wget https://raw.githubusercontent.com/Akachain/akc-admin/master/docker-compose.yaml
  

• Copy entire crypto artifact directory (e.g. crypto-config/, organizations/, channel-artifacts/) from your fabric network

• Now you should have the following files and directory structure.

  docker-compose.yaml
  example/artifacts/network-config.yaml
  example/organizations/
  example/chaincode/
  

• Edit network name and path to volumes to be mounted on akc-admin container (docker-compose.yaml) to align with your environment.

      networks:
        test:
          external:
              name: fabric_test
      ...
  
      services:
        admin:
          ...
  
          volumes:
            - ./example/organizations:/shared/crypto-config
            - ./example/channel-artifacts:/shared/channel-artifacts
            - ./example/artifacts/:/data/app/artifacts/
            - ./example/chaincode:/chaincodes
            - ./example/wallet:/data/app/wallet

Start container services

• Run the following to start up akc-admin services after starting your fabric network:

  $ docker-compose up -d

Clean up

• To stop services, run the following:

  $ docker-compose down
