How will fix Inaccessible issue for function app created in ILB ASE in azure?

Question

I am trying to create a function app in azure ILB ASE but failed to open Kudu due to its inaccessibility. How I configure it correctly?

Answer 1

Since the Azure function is deployed in ILB ASE, it can only be accessed from the virtual network. If you want to access the function outside the VNet, you need to deploy a public Azure application gateway to expose the internal endpoint. The Azure application gateway will work as a reverse proxy to route the incoming traffic to the appropriate endpoint.

Answer 2

Take a look at this issue - Document how to use Functions in an ILB ASE and this link, make sure you meet the requirements.

1. Be in the same vnet as your ILB ASE
2. Have a valid cert for the default domain and the default scm domain. *.yourILBDomain.com and *.scm.yourILBDomain.com
3. In addition to having a certificate, you also must configure the DNS for the ILB domain.
