Terraform Configuration Files

Please include all Terraform configurations required to reproduce the bug. Bug reports without a functional reproduction may be closed without investigation.

Happy to share the whole code (LaunchTemplate, ASG, ECS Cluster, VPC, and all the jazz), but the relevant part is:

resource "aws_ecs_capacity_provider" "autoscaling_group" {
  name = "example"

  auto_scaling_group_provider {
    auto_scaling_group_arn         = aws_autoscaling_group.asg.arn
    managed_termination_protection = "ENABLED"

    managed_scaling {
      instance_warmup_period    = 0
      maximum_scaling_step_size = 100
      minimum_scaling_step_size = 1
      target_capacity           = 90
      status                    = "ENABLED"
    }
  }
}

Expected Behavior

A minimum value of 0 should be allowed, as per aws-sdk-go:

"ManagedScalingInstanceWarmupPeriod": {
      "type": "integer",
      "max": 10000,
      "min": 0
    },

Actual Behavior

A minimum value of 1 is required based on the provider code in service/ecs/capacity_provider.go:

"instance_warmup_period": {
  Type:         schema.TypeInt,
  Optional:     true,
  Computed:     true,
  ValidateFunc: validation.IntBetween(1, 10000),
},

Steps to Reproduce

1. terraform apply
