Description

I was trying to setup a recurring cost budget with monthly budget planning option. Using the monthly budget planning option you can set planned budget limits for the budget period.

An improvement to the aws_budgets_budget would be to include the ability to set the PlannedBudgetLimits (map) using the AWS provider.

New or Affected Resource(s)

• aws_budgets_budget

Potential Terraform Configuration

resource "aws_budgets_budget" "cost" {
  name         = "monthly_cost_budget"
  budget_type  = "COST"
  time_period_start = "2021-01-01_00:00"
  time_unit         = "MONTHLY"

  PlannedBudgetLimits {
    Month1 = {
      limit_amount = "2000"
      limit_unit = "USD"
    },
    Month2 = {
      limit_amount = "2005"
      limit_unit = "USD"
    },
#... shortend 
    Month12 = {
      limit_amount = "2055"
      limit_unit = "USD"
    },    
  }
}

There are 3 budget methods available in the AWS Budgets API: Fixed, Planned, Auto-Adjusting. Today, there's only support for "planned."

Here's the related request for auto-adjusting: #23268
