Unable to deploy function to the Function App with Private Endpoints.

Akshay S Jaiswal 5 Microsoft Employee

We created a Virtual Network (Vnet) with two subnets: one designated for private endpoints (Private Subnet) and the other for Vnet integration of the function app (Function Subnet). The function app and its associated storage account were deployed within this setup, utilizing private endpoints to restrict public access. Additionally, private DNS zones were configured for both the function app and storage account to enable DNS resolution within the private network. The functions a deployed with the C# with .Net Core framework. Function App nslookup from the VM.

We also created the Self Hosted agent which resides in the same vnet and subnet where our function app is present. We are trying to deploy the resources using this self hosted and we are facing the below mentioned error.

Additionally , we have checked the NSG rules which are associated with PrivateSubnet. Attaching the screenshot for the same.

We are able to successfully deploy the App Settings for the Function App with the private endpoint attached to it. But failed to deploy the function for the Function App.
Please refer to the attached Screenshot for the App Settings.

Hi , Welcome to Microsoft Q&A You can monitor the disk space under “Quotas” tab at the function App level. Go to function App -> Quotas -> you can see the File System Storage as shown below If you see the available diskspace is less or zero and if you want to identify what is taking your disk space, you troubleshoot it by following any of the blog post Azure App Service - What is taking my disk space for my Azure Web App ?

@KapilAnanth-MSFT This is not a DevOps Related issue. Our pipelines our working fine. There is a Networking and Security related issue with DNS resolution or something.

@Deepanshukatara-6769 Hello , the above mentioned solution was not helpful to us as we have a created a brand new Function App and we have sufficient Quotas for the same.
