[Discussion] Deployment of ASP.NET 2.0.8 and .NET Core 2.1.0-rc1 to Azure App Service

[watashiSHUN]

Discussion issue for the Deployment of ASP.NET 2.0.8 and .NET Core 2.1.0-rc1 to Azure App Service
Azure/app-service-announcements#107

[davidebbo]

The deployment is now complete.

[saxx]

Where can I find information about deployment to Azure Germany?

[chrisgbaker]

Does this include both x86 and x64 runtimes?

[watashiSHUN]

it currently only has x86, but we are working on x64

[chrisgbaker]

Thanks for the info. Is there a timeline for x64? I haven't been able to successfully release an app targeting 2.1.300-rc1-008673 in azure (or preview releases for that matter), but at least having x64 support will help eliminate some variables. Currently our apps are being built via our agents with the x64 sdk, and we are trying to deploy to either 32 or 64 bit at this point.

[chrisgbaker]

Also, I've removed all extensions from the site slot. Is this now the approach, or do some still need to be installed?

[davidebbo]

Right, you don't need extensions for RC1. There is no exact ETA for 64 bit. In the meantime, you can just do a self-contained deployment.

[chrisgbaker]

@davidebbo, that doesn't seem to work either, and at this point I don't know what is wrong / misconfigured.

And at this point, The error I'm seeing fairly consistently is The specified CGI application encountered an error and the server terminated the process.. However, my app actually runs every now and then. If you hit https://qa-test-delivery-scratch.oasys.one/api/info/version, sometimes this will produce the correct json response.

In between pushing the release I've also tried the advice to delete the wwwroot folder via kudu, but that has no affect.

[davidebbo]

@chrisgbaker Simplest way to convey your issue is to share a minimal repo. Also, first try whether everything works for you with a vanilla new app. If that doesn't, then the specifics of your ap become irrelevant.

[chrisgbaker]

Kind of difficult when the issue isn't the repo; everything runs fine locally regardless of any of this. The issue is deploying to azure. Any advice in being able to more clearly convey issues when the App Service is part of the problem?

[davidebbo]

@chrisgbaker Please see the link I pointed to above. The whole idea is to share a repo such that if we deploy it to Azure, we observe the same thing that you observe. This makes it far easier than trying to make sense of snippets, and it makes sure that we are trying exactly the same thing.

[chrisgbaker]

https://github.com/chrisgbaker/azure_app_service_failure
@davidebbo Here is another project that is almost bare-bones that will not start in the App Service but will run locally.

[chrisgbaker]

Also, in that project I am targeting preview2 still, but changing to rc1 and modifying two lines of code to use Groups.AddToGroupAsync still refuse to start.

[davidebbo]

Thanks, we'll try to set up a repro. Are you trying to use the RC1 x86 that's on the box, or are you doing self-contained deployment (or have you tried both)?

[nsp5074]

@davidebbo any update on this? having the same issues (self contained or otherwise)

[davidebbo]

@npasqua I was waiting to hear back on the specific scenario. What do you mean by self contained or otherwise? Can you precisely describe what you are doing?

/cc @watashiSHUN

[nsp5074]

I've tried using the following when publishing directly to a new app service (created a new app service / resource group last thursday/friday) from Visual Studio

Target Framework: netcoreapp2.1
Deployment Mode: Framework-Dependent
Target Runtime: win-x86
and
Target Framework: netcoreapp2.1
Deployment Mode: Self-Contained
Target Runtime: win-x86

[davidebbo]

Can you deploy using 'Framework-Dependent' to a dummy test app and share its name for investigation?

See also this page for general investigation tips for Core on App Service.

[nsp5074]

https://test-2-1.azurewebsites.net/
https://test-2-1.azurewebsites.net/api-docs/ is a simple swagger page with the single endpoint that returns some git information
(I can confirm this same behavior working as expected with this code running in VS locally)

I actually am able to attach a debug process to the code in VS and set a breakpoint within the one endpoint. The breakpoint will actually be hit, but a 404 is returned instantly anyway.

It was published with
Target Framework: netcoreapp2.1
Deployment Mode: Framework-Dependent
Target Runtime: win-x86

[davidebbo]

https://test-2-1.azurewebsites.net/api-docs/ seems to work fine for me. Can you clarify what problem you are having? You only describe what you did to deploy, but I don't see anything in any of your comments that actually describes a problem. Please be as precise as you can be to help us understand your issue.

[nsp5074]

If you try to actually test the single endpoint on that swagger page, it should return a 404. You can also try calling it directly here https://test-2-1.azurewebsites.net/info/version

[davidebbo]

I see. And when that happens, is that reaching your code at all (e.g. check via tracing)? What debugging steps have you taken to try to further isolate? Make sure to enable all logging per this article above. Also, is there any evidence of a crash? i.e. if you look via Kudu process explorer, do you see the dotnet.exe process changing, or is it always the same one up and running?
