Azure-docs: Can't locate contract address..

Azure documentation issue guidance

• [x] The relevant Azure service or technology.

Deploying an Ethereum POA resource on Azure

• [x] A link to the published documentation article that you have feedback about.

https://docs.microsoft.com/en-us/azure/blockchain/templates/ethereum-poa-deployment#feedback

• [x] Clear, specific feedback that the author can act on.

I can't see where the contract address originates from.

// TODO Replace with your contract address
var address = "0xfe53559f5f7a77125039a993e8d5d9c2901edc58";

I have issued the command:

truffle migrate --network poa

but I do not see a contract address popping up for me.

My Truffle config file is as follows:

/*
 * NB: since truffle-hdwallet-provider 0.0.5 you must wrap HDWallet providers in a 
 * function when declaring them. Failure to do so will cause commands to hang. ex:
 */

var HDWalletProvider = require("truffle-hdwallet-provider");

var rpc_endpoint = "http://ethirgqw4-dns-reg1.eastus.cloudapp.azure.com:8540";
var mnemonic = "{redacted}";

module.exports = {
  networks: {
    development: {
      host: "localhost",
      port: 8545,
      network_id: "*" // Match any network id
    },
    "poa": {
      provider: new HDWalletProvider(mnemonic, rpc_endpoint),
      network_id: 10101010,
      gasPrice : 0
    }
  },
  compilers: {
    solc: {
      version: "0.4.23",
    }
  }
};

Thanks for the question. We are currently investigating and will update you shortly.

UPDATE:
I'm not able to see the contract address because the deployment is hanging.. Per the docs for truffle-hdwallet-provider you will need to wrap the provider in a function call;

 * NB: since truffle-hdwallet-provider 0.0.5 you must wrap HDWallet providers in a 
 * function when declaring them. Failure to do so will cause commands to hang. ex:

Even when I do this,

my migration deployment hangs and breaks after seeing this output:

Using network 'poa'.

@Sshetty2 Assigning the issue to the content author to help answer and evaluate your feedback. Thanks

@codyborn Can you take a look at this question?

Thanks,

29787 Any updates on this one? I haven't been able to make any headway

[Sshetty2]

@PatAltimore Is there anything you can do here? Have others had success running this demo; migrating their smart contracts to the network?

[PatAltimore]

@Sshetty2 I actually don't know this article very well. @codyborn is the actual author. However, everyone is heads down preparing for the //build conference next week. I don't expect a response from Cody until after build. The best place for support issues is the forum. https://social.msdn.microsoft.com/Forums/en-US/home?forum=azureblockchain.

@codyborn @PatAltimore Still waiting for feedback... The post on the forums has not received any replies..

Has this resource been deprecated?

[codyborn]

Hi @Sshetty2, apologies for the delay. I just saw this thread. I highly recommend giving our new VS Code extension a shot: https://marketplace.visualstudio.com/items?itemName=azblockchain.azure-blockchain
This has Truffle built-in with a simple right-click deploy experience.

[Sshetty2]

@codyborn that's great, I just gave this a shot. I was able to deploy my contract to the network and I received a mnemonic. I am guessing that I use the mnemonic to generate a contract address through Meta Mask. Please confirm.

[codyborn]

@Sshetty2 once you deploy the contract, it will have an address. You should be able to see the contract address by scrolling up through the console output. This will be more discoverable in the future :)

[Sshetty2]

@codyborn I do not see anything in the console output... Is it possible that there is a problem with the migration?

please see attached image

[codyborn]

@cnsegura, where can @Sshetty2 find the contract address in the extension output?

[cnsegura]

Hi @Sshetty2 - take a look at the attached animated .gif. You can see the contract address in the "Azure Blockchain" output channel in VS Code. You may have to scroll through the output to make sure you see the bottom of the data that gets sent to that output channel. In future revisions of the extension we will add the capability to get contract address at any time, not just at deployment in the window.

[Sshetty2]

Ok, got it, thanks.

It does appear that the tooling is a bit opinionated specifically because it seems that it will not find a nested truffle-config file and also it seems that it will not work with a build directory that is created through the truffle CLI.

In either case, I will launch a new project through the Azure Blockchain VS Code extension and attempt to incrementally add my project files including the client, client dependencies, and smart contract logic, then use the extension's build tooling to compile and deploy the contract and see if that does the trick. I'm sure that this should work.

Thanks for all of your help @codyborn @cnsegura

[codyborn]

Thanks for the follow up @Sshetty2. As this is a new extension we're constantly rolling out new features and improvements. Don't hesitate to send over feedback as you use it!

[Sshetty2]

@codyborn Thank you as well for the follow up. I'll certainly open any new issues in the Github repo for the tool itself unless there is a different preferred method for feedback.
