terraform中的任务执行IAM角色

如何解决terraform中的任务执行IAM角色

我正在创建一个IAM角色来执行任务。我已经在cloudformation中完成了工作，现在我正在以terraform进行操作，但是我遇到的问题是在cloudformation中有一个属性可以赋予ManagedPolicyArns，但您将如何在terraform中给出它。我同时附上了两个脚本。 Terraform脚本不完整，cloudformation脚本完成后我需要帮助，我想将其复制到terraform。

地形：

resource "aws_iam_role" "task_execution" {
  name               = "task-execution-${terraform.workspace}"
  assume_role_policy = <<EOF
{
    "Version": "2012-10-17","Statement": [
        {
        "Action": "sts:AssumeRole","Principal": {
            "Service": "ecs-tasks.amazonaws.com"
        },"Effect": "Allow","Sid": "","path": "/",}
  ]
}
EOF

  tags = {
    tag-key = "tag-value"
  }
}

                    - ecr:GetDownloadUrlForLayer 
                  Resource: '*'

解决方法

在Terraform中，您可以使用iam_role_policy_attachment资源将策略附加到角色：

resource "aws_iam_role_policy_attachment" "test-attach" {
    role       = aws_iam_role.test_role.name
    policy_arn = // ARN of the managed policy
}

,

SSSSSS仅用于 信任关系（即谁/谁可以担任此角色）。从而， 您的assume_role_policy应该是：

aws_iam_role

然后，所需的权限可以附加到角色，如下所示：

resource "aws_iam_role" "test_role" {
  name = "s3_access"

  assume_role_policy = <<EOF
{
    "Version": "2012-10-17","Statement": [
        {
            "Sid": "1","Effect": "Allow","Principal": {
              "Service": "ecs-tasks.amazonaws.com"
              },"Action": "sts:AssumeRole"            
        }
    ]
}
EOF

  tags = {
    tag-key = "tag-value"
  }
}
