1. Download files from repository.

Attention! If you want only run test project with docker files you may skip steps 2 and 3 below. Test project is in "kimlic" folder.

2. Install docker ce and docker-compose. Instructions you may find on official site docker.com

   Hint: If you face error "Unable to locate package `docker-ce`" after docker installation you may find solution here:
   https://unix.stackexchange.com/questions/363048/unable-to-locate-package-docker-ce-on-a-64bit-ubuntu?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa

3. Open script location in terminal and run script ('sudo ./setup.sh').

Setup:
"Would you like to use this with docker-compose support?" - yes.
"Please enter a project name:" - enter your name.
"Please enter the start port number [Default:22000]:" - you may set your own start port but default is ok.
"Please enter node name:" - node name.
"Lock key pair kim1 with password [none]:" and "Lock key pair kim1a with password [none]:" - default is ok.
"Is this a Block Maker Node?" - you need at least one block maker. 
"Is this the only block maker ? [y/N]:" - y.
"Is this a Voter Node? [y/N]:" - you need at least one voter.

Hint: looks like to create transaction on node it must be block maker or there is must be only one block creater node, but for now im not sure.

4. Open docker project directory and type "sudo docker-compose up". You should see nodes starting up. You may check nodes by sending request to rpc api. Open another terminal and run: curl -X POST --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":83}' localhost:22001 *use your port which you provided to installation script. In default case it will be 2200{index of node}. In my case 22000-22002.

To install truffle you may use this instruction https://www.techtonet.com/how-to-install-and-execute-truffle-on-an-ubuntu-16-04/ Replace text in file truffle.js in generated truffle project folder:

module.exports = {
  networks: {
    KIM1: {
      host: "127.0.0.1",
      port: 22000,
      network_id: "*",
      gasPrice: 0,
      gas: 4612388
    },
    KIM2: {
      host: "127.0.0.1",
      port: 22001,
      network_id: "*",
      gasPrice: 0,
      gas: 4612388
    },
    KIM3: {
      host: "127.0.0.1",
      port: 22002,
      network_id: "*",
      gasPrice: 0,
      gas: 4612388
    }
  }
}

• for now Quorum have 0 price of gas and transaction cost is 0 but account need at least 1 wei to send transaction. We can use truffle to send some ether to our account, follow steps below:

truffle cosole --network KIM3

You may use any network if they correctly configurated. When console opened:

web3.personal.listAccounts

In our case we had [ '0x639384d4c163fe8b00396a99190079732e072a25' ] account in response

web3.eth.sendTransaction({from:"0x639384d4c163fe8b00396a99190079732e072a25", to:"0x18d149f6a2a6ba0dec4ad38af21e984a7e978bd7", value:"0x1"});

Just in few seconds we will have 1 wei on our account. Then we may send transactions from our account using jsonrpc api.

privateFor must be public key of another node. You may found public key at [docker files location]/[node name]/keys/[node name].pub In case of invalid value for this param request will return "Non-200 status code..."). For nodes which are not indicated in "privateFor" any getter return 0x even for contract creator.
