Deployment fails on azure.de germanycentral

[Rainer-Kempkes]

Because of data privacy and legal issues we have to deploy to azure.de in Germany. Therefore I copied the content of the azuredeploy.json into a template deployment container and deployed it. I had to kick out the application_insights ressource and its dependencies because it is not available in germany. That was no prob. But then I ran into an error at the SAS_URI_Generator with Status "BAD_REQUEST": { "error": { "code": "InvalidContentLink", "message": "Unable to download deployment content from 'https://mc-n7okzt7dyzw66cb3dzxesxh2no.azurewebsites.net/Deployment/GenerateSASToken?parameters=key=nF8GESkTgKgwm4T9bLX6J7c1HLNX94jLfuD1MCxfAqTP2scde60hW2Ibq0ZnZ+JHbpBCE36hx/ol5qCfyjHKXQ==;trainer_size=Standard_D1_v2'. The tracking Id is '18ffadeb-bd71-4625-83d0-fbe82abc126b'. Please see https://aka.ms/arm-deploy for usage details." } }

Do you know what might have gone wrong? regards, Rainer

the related ressource in the azuredeploy.json would be: { "apiVersion": "2015-01-01", "name": "SAS_Uri_Generator", "type": "Microsoft.Resources/deployments", "dependsOn": [ "Microsoft.Resources/deployments/Management_Center" ], "properties": { "mode": "incremental", "templateLink": { "uri": "[concat(reference('Microsoft.Resources/deployments/Management_Center').outputs.url.value, '/Deployment/GenerateSASToken?parameters=key=', reference('Microsoft.Resources/deployments/Storage').outputs.userStorageAccountKey.value, ';trainer_size=', parameters('online Trainer VM Size'))]" } } },

I think I found the bug. In the file "WebEmptyTemplate.json" in the outputs-section you create a URL ending with ".net":

"value": "[concat('https://', variables('siteName'), '.azurewebsites.net')]"

whereas in German Azure the correct suffix would be ".de".

I will try to avoid this by editing the main JSON template and put the text of the WebEmptyTemplate into the main template. Hope this helps...

Maybe I’m missing something here, but shouldn’t you be able to simply select azure.de as region?

I grepped through the codebase to look for more azurewebsites.net references. There are a few other places but only related to testing and email notification when finished.

Can you make the domain suffix a parameter of the main deploy.json and set the default to azurewebsites.net?

Hi Markus,

I am still struggling with the deployment on azure.de, but I will change the main deploy.json and make a pull request after I've found the solution.

But prior to that I have some questions about customizing my existing deployment on azure.com. For a proof of concept I need to do some changes in the configuration. 1) Where and how can I customize a) the context features? Or is the only way to change the posted JSON? Is there a consistency check if a context feature changes? b) the action features? MWT has to know the amount of actions to chose randomly and to learn from... c) actions? define action features?

2. model extraction: I extracted the current model vom blob storage, but it contained many hex values and I couldn't read it. Which format is it?

3. Moving to a productive environment: which actions would you advise to harden the system? The trainer f.e. is running on http, are there any intrusion detection tools running etc.?

Cheers, Rainer

Hi,

1a) Yes you can customize the JSON features. See some documentation here: https://github.com/JohnLangford/vowpal_wabbit/wiki/JSON - no consistency check. We’re using Vowpal Wabbit as the ML library which is schemaless. 1b) We support variable number of actions with each request. I’d say that’s the primary usecase c) _multi and then features within that. See above link at the very end. 2) It’s VW. You need to use vw -i model.file –readable_model model.txt (make sure to use proper dashes, not the one in the email). Since VW hashes everything you’d have to feed data and use –invert_hash to get the mappings). 3) The trainer is feeding of EventHub for data, the HTTP interface is only for management. The HTTP you see runs on a different set of servers. You can also integrate using the C# client library, which from a security perspective probably helps you a bit.

I’d suggest to have a quick Skype meeting to give you a bit more guidance. Contact me on marcozo@microsoft.commailto:marcozo@microsoft.com and we can coordinate on time.
