Orleans Azure Worker/Web Api Client not connecting #308

Closed jptaylor226 closed 9 years ago

jptaylor226 commented 9 years ago

Project Orleans gurus,

My group at work is considering getting heavily invested with the implementation of our next gen system, but I keep running into the seemingly common exception: [System.AggregateException: One or more errors occurred. ---> Orleans.Runtime.OrleansException: Target silo is unavailable]

I'm currently running 1.0.5 (glad to be rid of the SDK for codegen). The silos are hosted in a worker role of an azure service; the client is a Web Api, hosted as an azure web site. It looks like the client resolves the location of the silos, but is unable to connect.

My current set of (sanitized) configs are as follows: Azure Service: ServiceConfiguration.Cloud.cscfg: <?xml version="1.0" encoding="utf-8"?> <ServiceConfiguration serviceName="HanoiCloud" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration" osFamily="4" osVersion="*" schemaVersion="2014-06.2.4"> <Role name="HanoiWorker"> <Instances count="2" /> <ConfigurationSettings> <Setting name="DataConnectionString" value="DefaultEndpointsProtocol=https;AccountName=[foo];AccountKey=[foo Key]" /> </ConfigurationSettings> </Role> </ServiceConfiguration>

I spot the following

2015-04-06T20:03:47 PID[38708] Error Error opening trace file Client-2015-04-06-20.03.46.894Z.log -- Using DefaultTraceListener instead -- Exception=System.UnauthorizedAccessException: Access to the path 'D:\Windows\system32\Client-2015-04-06-20.03.46.894Z.log' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

Could that trigger the first exception and consequently disallow connecting?

sergeybykov commented 9 years ago

Good catch, @veikkoeeva!

@jptaylor226 Try to specify a full path in TraceToFile.

veikkoeeva commented 9 years ago

@jptaylor226, @sergeybykov A quick one before sauna. I wonder if this has also something to with that the API is on a website and the silos in a Worker Role, so in a different subnet and no possibility to have even a VNET in between (I recall one couldn't attach web sites to a VNET, but that might have changed already). I remember there's a lengthy discussion about that somewhere in Codeplex, but I could only find this. In any event, I slap it here in case it's useful on itself.

jptaylor226 commented 9 years ago

I made an effort to remove the Trace configurations from both the client and worker role and redeployed to azure, but the behavior remains unchanged-- still getting the "Target silo is unavailable" message. Based on the codeplex discussion, it seems the error is mostly in my mental model. If I understand correctly now, the worker role needs to be configured as a silo client, and one of many appropriate designs might be to have the worker role subscribe to the an azure queue or topic, and then send messages to grains.

sergeybykov commented 9 years ago

@jptaylor226 Are you deploying silos and client as part of the same hosted service? You mentioned Azure web site, so I suspect that's not the case. This is not supported due to the lack of direct TCP connectivity from outside of a hosted service. You would need a virtual network configured across them, but I'm not sure if somebody tried that.

If I understand correctly now, the worker role needs to be configured as a silo client

In a typical topology, a worker role is used for hosting silos and a web role (IIS) or another worker role (non-IIS HTTP server) hosting clients (frontends). Only the frontends need to be configured as silo clients.

jptaylor226 commented 9 years ago

Thanks for the quick help, Sergey-- I'm making the transition from local test environment to closer to production, so I have some work to do. Moving on to making another worker in the same service at this point, will post an update on this thread.

jptaylor226 commented 9 years ago

OK-- so went ahead and used this walkthrough (http://www.asp.net/web-api/overview/hosting-aspnet-web-api/host-aspnet-web-api-in-an-azure-worker-role) to make a Web Api role in the azure cloud service, and things seem to work.

sergeybykov commented 9 years ago

Great!

2mike2 commented 9 years ago

Using vnet with silos and web clients in separate deployments worked for me.
