Terminal Commands

Starting the Network and Running the Application

1. Navigate to the cbps-network directory:

cd cbps-network

2. Run the following command to start the network and create a channel:

./network.sh up createChannel -c bankschannel -ca -s couchdb0

3. Deploy the chaincode by running the following command:

./network.sh deployCC -c bankschannel -ccn bank -ccp ../crossBorderPayment/chaincode-go/ -ccl go -ccep "OR('Org1MSP.peer','Org2MSP.peer')"

4. Navigate to the crossBorderPayment/application directory:

cd ../crossBorderPayment/application

5. Install the required dependencies using npm:

npm install

6. Run the following commands to enroll the admin users:

node enrollAdmin.js org1
node enrollAdmin.js org2

7. Start the application by running the following command:

node app.js

If there are no errors, the explorer interface will be accessible at http://localhost:3000.

Explorer Configuration

1. Modify the necessary files for the explorer:

   • Take the name of the file in the cbps-network/organizations/peerOrganizations/org1.example.com/users/[email protected]/msp/keystore directory.
   • Change the end of the adminPrivateKey value in the explorer/cbps-network.json file.

2. Navigate to the explorer directory:

cd explorer

3. Run the following command to start the Docker containers:

docker-compose up

4. If there are no errors, the explorer interface will be accessible at http://localhost:8080.

Stop and Clear Network

1. Navigate to the cbps-network directory:

cd cbps-network

2. Run the following command to shut down the network:

./network.sh down

3. Navigate to the crossBorderPayment/application directory:

cd ../crossBorderPayment/application

4. Delete the wallet and node-modules directories:

rm -rf wallet
rm -rf node-modules
