Azure – Determine deployed extensionBundle version

I configured an Azure Function App for Windows with some version range for extensionBundle as recommended via host.json.

{
  "version": "2.0",
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[4.0.0, 5.0.0)"
  }
}

Is there s way to determine, which version of the bundle is actually used by the deployed Function App ?

With the concrete version of the bundle, I could also determine the versions of the specific extensions (see bundle releases).

I thought, there is a way using the Kudu console. But I wasn’t able to find the information.

    In addition to accepted answer, you can also use the Console view (Development Tools section) of your Function App in the Azure Portal directly.

    > cd C:homeLogFilesApplicationFunctionsHost
> grep -A1 -e 'ExtensionBundle' *.log
2024-02-12T07-24-22Z-575394f180.log:    "id": "Microsoft.Azure.Functions.ExtensionBundle",
2024-02-12T07-24-22Z-575394f180.log-    "version": "4.12.0"
[..]

    The example output points to the release 4.12.0.

    You can find the exact extension bundle version of Azure function app in KUDU site.

    • I have created a dotnet Http triggered Azure function app in Portal.

    Host.json:

    {
  "version": "2.0",
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[4.*, 5.0.0)"
  }
}
    • To determine the extension bundle of function app, navigate to its KUDU site(https://kpfnc.scm.azurewebsites.net)=>Debug Console=>LogFiles=>Application=>Functions=>Host=> select the log file, click on edit:

    • The extension bundle version can be seen in the logs as shown below:
