Deployment Issue in Azure Web App

Question

I am trying to make a Python Application Deployment in Azure Web App. The Deployment is within the private network, and we have VNet and Azure Private Endpoints in place to secure the application.

But while deploying the application which was previously successfully deployed an error has occurred

Error: Oops... An unexpected error has occurred.\nError: System.AggregateException: Http request to retrieve the SDKs available to download from 'https://oryx-cdn.microsoft.io' failed. Please ensure that your network configuration allows traffic to required Oryx dependencies, as documented in 'https://github.com/microsoft/Oryx/blob/main/doc/hosts/appservice.md#network-dependencies'\nSystem.AggregateException: One or more errors occurred.

Can anyone help to resolve the issue

Answer 1

@Shubhankar Khandai , Apologies for the delayed response.

Just to highlight, when using ZipDeploy, Oryx is not enabled by default since you are using an External builder. If you prefer to enable App Service Build Service (Oryx) then you need to add a new App Setting SCM_DO_BUILD_DURING_DEPLOYMENT= true and redeploy.

1.Please set the SCM_DO_BUILD_DURING_DEPLOYMENT app setting to 1. This forces Oryx to build your application during deployment. Check out the step-step instructions outlined in this doc: How to set : Configure an App Service app

2.Review if the Oryx CDN endpoint is whitelisted in VNET.

When using App Service with a Virtual Network, you will need to allow outbound access from the webapp to oryx-cdn.microsoft.io on port 443. oryx-cdn.microsoft.io hosts the Oryx packages corresponding to each SDK language and version. If this network dependency is blocked, then App Service will not be able to build your application using Oryx.

If the issue still persists,

3.SSH into Kudu using https://<your_sitename>.scm.azurewebsites.net/newui/kududebug and review **/tmp/build-debug.log **- to fetch more details.

Kindly let us know how it goes, I'll follow-up with you further.
