1. Modify src/main/resources/application.properties file. Set gcloud.dir property to the directory where gcloud installed. Default value is /usr/bin/

   The default value of working.dir property is "./blockchain/artifacts/". The service will use that directory to store templates and files generated by the service.

2. In project directory, run ./gradlew bootRun

3. The restful service endpoint is POST: localhost:9000/gbaas/fabric?create_instance=false&install_software=false$install_example_chaincode=true

   The request body looks like below:

   {
       "domain": "sample-network",
       "gcpProjectName": "hyperledger-poc",
       "gcpZoneName": "us-east1-b",
       "ordererName": "orderer-google-boa",
       "channelName": "common",
       "properties": [
           {
               "org": "google",
               "numOfPeers": 2
           },
           {
               "org": "boa",
               "numOfPeers": 2
           }
       ]
   }
   

   The domain property will be used for setting up the instance name, e.g orderer.sample-network.

4. If you choose to install the example chaincode, you can ssh to a peer, e.g. boa-peer0, the initiate chaincode with command like: peer chaincode instantiate -o orderer.sample.com:7050 --tls --cafile /etc/hyperledger/crypto/orderer/tls/ca.crt -C common -n example -v 1.0 -c '{"Args":["init","a","100","b","200"]}' then query from another peer: peer chaincode query -C common -n example -c '{"Args":["query","a"]}'

Make sure you cryptogen and configtx command are in ~/bin/

if you don't have those binaries, simply run curl -sSL https://goo.gl/6wtTN5 | bash

Make sure you set up JDK for Gradle

It's easier to use IDE to set up the project

Don't forget to run watch -n60 gcloud compute --project=hyperledger-poc firewall-rules create all --direction=INGRESS --priority=1000 --network=default --action=ALLOW --rules=all --source-ranges=0.0.0.0/0
