Azure Functions consumption plan naming

Question

I've created a new Function App in Azure. I picked a consumption plan for the App Service Plan.

Once the app is created I now have a new App Service Plan called "WestEuropePlan" In my resource group.

Next thing. IT department says "WestEuropePlan" is not the correct naming convention for App Service Plans.

What are my options. When creating the Function App Im not allowed to pick or name an existing plan when using consumption based plans.

I cannot rename my autogenerated plan.

I cannot manually create a consumption based plan previous to creating the Function App.

What do i do? Is my only option to not use Consumption based plans and instead create a normal app service plan that I can name myself?

Is there something I can do from azure CLI or using ARM templates?

Answer 1

Above answers will help if you are doing using Azure CLI, if you want to do via Portal itself, you can do as follows,

1. On the Azure function Review + create step, there is an option to Download the template for automation and you can click on it. Then the Template will be displayed for downloading.
2. Now click on Deploy
3. Now you can easily change the Hosting Plan Name, agree to T&Cs and click on Purchase.

You can create a Azure Function on Consumption plan with your choice of name for consumption plan using ARM Template. Below is the sample template and parameter file:

You can create from this ARM Template. No app insights and it'll ask appName, hostingPlanName, storageAccountName, storageAccountType, location and runtime
