Terraform scenarios to associate AWS IAM role with ECS task definition due to circular dependency
I've looked through the documentation and I'm still confused about I tried several approaches but none seem to work. I'm working on a project and hit a roadblock... I'm trying to set up an AWS ECS service using Terraform, but I'm running into a circular dependency scenario when attempting to associate an IAM role with my task definition. The behavior I'm working with is: ``` behavior: Cycle: aws_iam_role.task_role, aws_ecs_task_definition.my_task ``` I have declared the IAM role and the ECS task definition in the same Terraform configuration, and it seems that both resources are depending on each other in a way that Terraform need to resolve. Here's a simplified version of my Terraform code: ```hcl resource "aws_iam_role" "task_role" { name = "my_task_role" assume_role_policy = data.aws_iam_policy_document.assume_role_policy.json } resource "aws_ecs_task_definition" "my_task" { family = "my_task_family" task_role_arn = aws_iam_role.task_role.arn execution_role_arn = aws_iam_role.execution_role.arn container_definitions = jsonencode([ { name = "my_container" image = "my_image:latest" cpu = 256 memory = 512 essential = true } ]) } data "aws_iam_policy_document" "assume_role_policy" { statement { actions = ["sts:AssumeRole"] principals { type = "Service" identifiers = ["ecs-tasks.amazonaws.com"] } } } ``` I've tried to break this cycle by creating a separate module for the IAM roles, but that didn't seem to resolve the scenario. I also considered using `depends_on` on the ECS task definition, but it's not clear how that would help in this case. Any suggestions on how I can successfully link the IAM role with the ECS task without causing circular dependencies? Is there a better way to structure these resources to avoid this scenario? How would you solve this? What am I doing wrong? I'm working on a application that needs to handle this. Any ideas what could be causing this?
