Concensus Management using a Hyperledger Fabric blockchain
- Docker
- Docker-compose
- Node 8.x
NOTE: MUST be Node 8.x to work with hyperledger. NVM (Node version manager) can be used to allow use of Node 8.x if a different version of node is already installed.
Mac/Linux may be required to run the scripts included with hyperledger, although it is possible Git Bash may allow for running on Windows
git clone https://github.com/lukebaal/CloudProject.git
npm install -g composer-cli composer-rest-server
cd hyperledger
./createPeerAdminCard.sh
cd consensus-network
composer archive create -t dir -n .
NOTE: The cd command below assumes you are in hyperledger/consensus-network directory from previous steps
cd ../../
npm --prefix ./backend install
npm --prefix ./frontend install
npm --prefix ./frontend run build
This will install the dependencies for the backend/frontend and build the frontend
In one terminal
./startup.sh
This will startup the Hyperledger network and start the Composer REST API
In another terminal
docker-compose up
This will start the database container
In another terminal
cd backend
NODE_ENV=production npm start
This will start the backend in production, which serves the frontend
Navigate to localhost:5000 in a browser to access the application
If issues using hyperledger, refer to the documentation.
Hyperledger Fabric: https://hyperledger-fabric.readthedocs.io/en/latest/
Hyperledger Composer: https://hyperledger.github.io/composer/latest/installing/installing-index.html
If actions such as users adding/editting permissions or companies adding their info are hanging (Button says "Sending...."), then it is likely an issue with the Composer REST API. More specifically, it seems the GRPC connection timesout if the network is running long enough without any requests.
Solution: run startup.sh again to restart the network.
