Amazon web services Terraform模块参数VAR是必需的，但未找到定义

我有地形模块来提供AWS资源。在

地形图之后

，我看到以下错误：

错误：缺少必需的参数 在main.tf行的模块“ecs任务执行角色”中： 113：模块“ecs任务执行角色”{ 参数“iam_role_name”是必需的，但未找到定义

这是我在

。/terraform/modules/iam/ecs_iam.tf

中定义的资源：

resource "aws_iam_role" "iam--task-execution-role" {
  name               = var.iam_role_name
  assume_role_policy = data.aws_iam_policy_document.ecs-task-assume-role.json
}

data "aws_iam_policy_document" "ecs-task-assume-role" {
  statement {
    actions = ["sts:AssumeRole"]

    principals {
      type        = "Service"
      identifiers = ["ecs-tasks.amazonaws.com"]
    }
  }
}

data "aws_iam_policy" "ecs-task-execution-role" {
  arn = "arn:aws:iam::aws:policy/service-role/AmazonECSTaskExecutionRolePolicy"
}

# Attach the above policy to the execution role.

resource "aws_iam_role_policy_attachment" "ecs-task-execution-role" {
  role       = aws_iam_role.iam-task-execution-role.name
  policy_arn = data.aws_iam_policy.ecs-task-execution-role.arn
}

variable "iam_role_name" {
  type = string
}

module "iam-jo-task-execution-role" {

  source = "../modules/iam"

  iam_role_name = "iam-jo-task-execution-role"

}

# Attach the above policy to the execution role.

module "ecs-task-execution-role" {

  source = "../modules/iam"

}

变量在

。/terraform/modules/iam/Variables.tf中定义：

resource "aws_iam_role" "iam--task-execution-role" {
  name               = var.iam_role_name
  assume_role_policy = data.aws_iam_policy_document.ecs-task-assume-role.json
}

data "aws_iam_policy_document" "ecs-task-assume-role" {
  statement {
    actions = ["sts:AssumeRole"]

    principals {
      type        = "Service"
      identifiers = ["ecs-tasks.amazonaws.com"]
    }
  }
}

data "aws_iam_policy" "ecs-task-execution-role" {
  arn = "arn:aws:iam::aws:policy/service-role/AmazonECSTaskExecutionRolePolicy"
}

# Attach the above policy to the execution role.

resource "aws_iam_role_policy_attachment" "ecs-task-execution-role" {
  role       = aws_iam_role.iam-task-execution-role.name
  policy_arn = data.aws_iam_policy.ecs-task-execution-role.arn
}

variable "iam_role_name" {
  type = string
}

module "iam-jo-task-execution-role" {

  source = "../modules/iam"

  iam_role_name = "iam-jo-task-execution-role"

}

# Attach the above policy to the execution role.

module "ecs-task-execution-role" {

  source = "../modules/iam"

}

模块位于
。/terraform/production/main.tf
：

resource "aws_iam_role" "iam--task-execution-role" {
  name               = var.iam_role_name
  assume_role_policy = data.aws_iam_policy_document.ecs-task-assume-role.json
}

data "aws_iam_policy_document" "ecs-task-assume-role" {
  statement {
    actions = ["sts:AssumeRole"]

    principals {
      type        = "Service"
      identifiers = ["ecs-tasks.amazonaws.com"]
    }
  }
}

data "aws_iam_policy" "ecs-task-execution-role" {
  arn = "arn:aws:iam::aws:policy/service-role/AmazonECSTaskExecutionRolePolicy"
}

# Attach the above policy to the execution role.

resource "aws_iam_role_policy_attachment" "ecs-task-execution-role" {
  role       = aws_iam_role.iam-task-execution-role.name
  policy_arn = data.aws_iam_policy.ecs-task-execution-role.arn
}

variable "iam_role_name" {
  type = string
}

module "iam-jo-task-execution-role" {

  source = "../modules/iam"

  iam_role_name = "iam-jo-task-execution-role"

}

# Attach the above policy to the execution role.

module "ecs-task-execution-role" {

  source = "../modules/iam"

}

感谢您的帮助。
在您的示例中：

module "iam-jo-task-execution-role" {

  source = "../modules/iam"

  iam_role_name = "iam-jo-task-execution-role"

}

# Attach the above policy to the execution role.

module "ecs-task-execution-role" {

  source = "../modules/iam"

}

您没有将
iam\u role\u name
变量的值传递给
ecs task execution role
模块。正上方的
iam jo task execution role
模块显示了如何将变量传递给模块。
结果是我误解了Terraform中的资源和模块

在
。/terraform/production/main.tf
文件中，我需要以下语法，该文件声明了在源
。/modules/iam
中找到的资源的使用：

module "iam-jo-task-execution-role" {

  source = "../modules/iam"

  iam_role_name = "iam-jo-task-execution-role"

}

无需为
。/terraform/modules/iam/ecs_iam.tf
中声明的每个资源定义一个模块。这只是几个资源的分组（打包）。
哪个文件用于
。/modules/iam
中的模块？上面的路径不正确。是的，它是
。/modules/iam
。
