创建 IAM 角色并向其附加策略时出错

Question

我正在尝试创建一个 lambda 角色并将策略附加到它，以便它可以启动和停止 ec2 实例。我将使用 cloudwatch 触发 lambda。

我收到此错误：“错误：错误创建 IAM 角色 lambdaRole：MalformedPolicyDocument：JSON 字符串不能有前导空格状态代码：400，请求 ID：d6a86c41-6601-43af-9040-81f6e6a76ec8

在 iam.tf 第 11 行，在资源 "aws_iam_role" "lambdaRole": 11: 资源 "aws_iam_role" "lambdaRole" {"

 terraform {
    backend  "s3" {
    region         = "us-west-2"
    bucket         = "gitlegionbucket"
    key            = "ec2/terraform.tfstate"
    dynamodb_table = "tf-state-lock"
    }
}

resource "aws_iam_role" "lambdaRole" {
  name = "lambdaRole"

  assume_role_policy = <<EOF

我也面临同样的错误。我直接从问题中复制了代码。

它的工作方式对我来说是在行之后立即启动{ie 策略的开始，EOF没有任何空格。

resource "aws_iam_role" "lambdaRole" {
  name = "lambdaRole"

  assume_role_policy = <<EOF
{
    "Version": "2012-10-17",
    "Statement": [
    {
        "Action": "sts:AssumeRole",
        "Principal": {
        "Service": "ec2.amazonaws.com"
        },
        "Effect": "Allow",
        "Sid": ""
    }
    ]
}
EOF
}

resource "aws_iam_policy" "policy" {
  name        = "test-policy"
  policy = <<EOF
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "logs:CreateLogGroup",
        "logs:CreateLogStream",
        "logs:PutLogEvents"
      ],
      "Resource": "arn:aws:logs:*:*:*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "ec2:Start*",
        "ec2:Stop*"
      ],
      "Resource": "*"
    }
  ]
}
EOF
}

resource "aws_iam_role_policy_attachment" "attach-policies" {
  role       = "${aws_iam_role.lambdaRole.name}"
  policy_arn = "${aws_iam_policy.policy.arn}"
}

地形输出：
