install testrpc as your local geth-rpc or use the Docker image - if you run into problems building the image on Windows, simply build it in the Ubuntu subsystem on Windows. Here a description how to use the windows docker daemon from within the Linux subsystem.
follow these instructions to install geth
simply deploy the follwoing arm template: https://github.com/Azure/azure-quickstart-templates/tree/master/go-ethereum-on-ubuntu
Once the resource has been deployed, create a VPN to ensure the VM is isn't publicly accessible. Add a the geth-rpc port 8545 as an inbound security rule to the Nnewtwork security group (in addition to ssh). Also allow outbound traffic on all ports (or the geth peer network port only (which is ????)) to ensure that geth can connect to it's peers.
To create the VPN, it might be best to first deploy the services and create the VPN including the gateway through the WebApp's Networking settings. This will allow to create a VPN which includes the vpn gateway.
install truffle
sudo apt-get update && sudo apt-get -y upgrade
sudo apt-get -y install curl git vim build-essential
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo npm install -global express
sudo npm install -global truffle
On Windows: before you install truffle ensure you install windows-build-tools
npm install -global --production windows-build-tools
npm install -global truffle
start test-rpc:
docker run -d -p 8545:8545 ethereumjs/testrpc:latest -a 10 -u0 -u1
or in attached mode to see the transactions:
docker run -p 8545:8545 ethereumjs/testrpc:latest -a 10 -u0 -u1
Ensure that the VM is accessible from a private network only. To ssh into it, a jumperBox vm can be used (a vm that acts which provides public ssh but is part of the VPN).
Setup your Rinkeby Testnet by following this article
NOte: ensure that you start geth by enabling rpc and web3:
geth ... --rpc --rpcport=8545 --rpcaddr=0.0.0.0 --rpcapi="personal,admin,eth,net,web3"
you can check the accessability of your geth rpc endpoint within your private network using the following curl command:
curl -X POST --data '{"jsonrpc":"2.0","method":"web3_clientVersion","params":[],"id":1}' http://10.0.0.4:8545
Before we can deploy the contract, geth needs to be fully synched with he the blockchain. We can check the progress through the console:
> eth.syncing
{
currentBlock: 484548,
highestBlock: 1140339,
knownStates: 338331,
pulledStates: 148121,
startingBlock: 440322
}
Once we're finished with syncing eth.blockNumber returns a the number of the latest block. While syncing, it returns 0
unlock your account:
personal.unlockAccount(web3.eth.coinbase, "password", 15000)
in your truffle.js add a property for your network:
networks: {
testnet: {
host: "10.0.0.4",
port: 8545,
network_id: "4"
}
}
deploy the contract from your jumperBox:
truffle migrate --reset --network testnet
Set the hostname in `truffle.js" to your deployed geth rpc instance - e.g. 10.0.0.4
Just compile and deploy the contracts
truffle compile
truffle migrate --reset
Once the block containing the contract has been added to the chain, we can test it:
truffle test
Make sure you have Node.js version 7.6.0 and above. Run the following command to deploy the script to any RPC endpoint:
node deploy.js <CONTRACT_NAME> <RPC_ENDPOINT> <COINBASE_PASSWORD>
Example:
node deploy ProofOfProduceQuality http://40.68.224.232:8545 MyPassword
In case of an error, the process will be terminated with an error exit code and the last output line will be a json containing an error member with the details of the error:
{"error":"the error details"}In case of a successful execution, the process will be terminated with a success exit code (0) and the last output line will be a json containing the account address (the coinbase) and the deployed contract instance address:
{"accountAddress":"0x6290feb5d6155bb8ca4551bae08564afb636a974","contractAddress":"0x44D89F52f93D1bF9A0F47330B5726B0d82cD8176"}
