Hi. This should be used to make it work on ECS

Thanks for the modules!

Hi @okanaiki, thanks for your message, glad you find the modules useful. I don't understand the message, is there anything not working?

[okanaiki]

In this setup to make it work as expected i changed to

resource "aws_appautoscaling_policy" "ecs_policy"
resource "aws_appautoscaling_target" "ecs_target"

from

resource "aws_appautoscaling_policy" "scale_down_policy"
resource "aws_appautoscaling_policy" "scale_up_policy"
resource "aws_appautoscaling_target" "scale_target"

and added this variables
min_capacity = var.scale_target_min_capacity
max_capacity = var.scale_target_max_capacity

to all the modules from setup to main https://github.com/cn-terraform/terraform-aws-ecs-fargate

then autoscaling for ecs start to work as expected
