Install a Development Hyperledger Fabric in a Microsoft Azure VM

These instructions will allow you to setup your own virtual machine on Microsoft Azure with Hyperleger Fabric blockchain with the Clause Audit Trail chaincode running.

Install the Azure CLI

Following these instructions: https://docs.microsoft.com/en-us/cli/azure/install-azure-cli-macos?view=azure-cli-latest

Deploy Hyperledger Fabric and Audit Trail chaincode

Run the azure-deploy.sh script to deploy HLF to Azure in a VM. The script will take about 10 minutes to complete.

Copy the Connection Profile JSON

At the end of the script you should see the connection profile for the Hyperledger Fabric printed. It will look something like this:

{
    "name": "basic-network",
    "version": "1.0.0",
    "client": {
        "organization": "Org1",
        "connection": {
            "timeout": {
                "peer": {
                    "endorser": "300",
                    "eventHub": "300",
                    "eventReg": "300"
                },
                "orderer": "300"
            }
        }
    },
    "channels": {
        "mychannel": {
            "orderers": ["orderer.example.com"],
            "peers": {
                "peer0.org1.example.com": {}
            }
        }
    },
    "organizations": {
        "Org1": {
            "mspid": "Org1MSP",
            "peers": ["peer0.org1.example.com"],
            "certificateAuthorities": ["ca.org1.example.com"]
        }
    },
    "orderers": {
        "orderer.example.com": {
            "url": "grpc://xxxxx.uksouth.cloudapp.azure.com:7050"
        }
    },
    "peers": {
        "peer0.org1.example.com": {
            "url": "grpc://xxxxx.uksouth.cloudapp.azure.com:7051"
        }
    },
    "certificateAuthorities": {
        "ca.org1.example.com": {
            "url": "http://xxxxx.uksouth.cloudapp.azure.com:7054",
            "caName": "ca.org1.example.com",
            "registrar": [{
                "enrollId": "admin",
                "enrollSecret": "adminpw"
            }],
            "x-mspid": "Org1MSP"
        }
    }
}

Copy this and save it into a file called connection-profile.json. You will need this file to connect your Clause account to Hyperledger Fabric via the Hyperledger Fabric App.

Add User to docker group

Login to your VM using ssh. Scroll to the top of the script output and you will see the IP address for your VM.

ssh <my-ip-address>

In the remote VM, then add yourself to the docker group and then exit the VM:

sudo usermod -aG docker <my-user-name>
exit

Log back into the VM via ssh and verify that you have docker access:

ssh <my-ip-address>
docker ps -a

You should see output like this:

$ docker ps -a

Tail the chaincode logs

You can use the docker logs -f command to inspect the logs for the audit trail chaincode container. Replace 1804f00188d0 with the id for your chaincode container (printed by docker ps).

docker logs -f 1804f00188d0

> clause@1.0.0 start /usr/local/src
> node clause.js "--peer.address" "peer0.org1.example.com:7052"
