创建自动缩放计划操作时出错

Question

我正在尝试在特定时间范围内停止和启动与 ASG 映射的 EC2 实例。即使在授予角色适当的权限后，我仍然收到访问被拒绝的错误。

resource "aws_autoscaling_group" "asg" {
  availability_zones        = "${var.availability_zones}"
  name                      = "${var.environment}-airflow-asg"
  launch_configuration      = "${aws_launch_configuration.lc.name}"
  target_group_arns         = ["${aws_lb_target_group.lb_tg.arn}"]
  max_size                  = "${var.asg_max_size}"
  min_size                  = "${var.asg_min_size}"
  desired_capacity          = "${var.asg_desired_capacity}"
  health_check_grace_period = "300"
  health_check_type         = "EC2"
  vpc_zone_identifier       = ["${data.aws_subnet.app_subnet_0.id}", "${data.aws_subnet.app_subnet_1.id}"]
  force_delete              = true

  lifecycle {
    create_before_destroy = true
  }

  tags = [merge(
    var.common_tags,
    map("Classification", "private"),
    map("Name", "${var.environment}-airflow-asg"),
    map("key", "Name", "value", "${var.environment}-airflow", "propagate_at_launch", true)
  )]
}
# Stop instances each weekday at 6pm
resource "aws_autoscaling_schedule" "asg_stop" {
  scheduled_action_name  = "${var.environment}-asg_stop"
  min_size               = 0
  max_size               = 0
  desired_capacity       = 0
  recurrence             = "00 18 * * MON-FRI"
  autoscaling_group_name = "${aws_autoscaling_group.asg.name}"
}

# Startup instance each weekday at 8am
resource "aws_autoscaling_schedule" "asg_start" {
  scheduled_action_name  = "${var.environment}-asg_start"
  min_size               = "${var.asg_min_size}"
  max_size               = "${var.asg_max_size}"
  desired_capacity       = "${var.asg_desired_capacity}"
  recurrence             = "00 08 * * MON-FRI"
  autoscaling_group_name = "${aws_autoscaling_group.asg.name}"
}

执行后出错terraform apply:

Answer 1

您混淆了名称相似的 application-autoscaling and autoscaling IAM 策略。

Application autoscaling 用于扩展 ECS 服务和 DynamoDB table read/write 容量等。

另一种类型 autoscaling 是更标准的 EC2 自动缩放，它可以扩展实例组，这正是您在那里拥有的自动缩放组所需要的。

因此，要解决此问题，只需将 application-autoscaling:* 操作更改为 autoscaling:*:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "RDSPermissions",
            "Effect": "Allow",
            "Action": [
                "rds:*",
                "autoscaling:DeleteScalingPolicy",
                "autoscaling:DeleteScheduledAction",
                "autoscaling:DeregisterScalableTarget",
                "autoscaling:DescribeScalableTargets",
                "autoscaling:DescribeScalingActivities",
                "autoscaling:DescribeScalingPolicies",
                "autoscaling:PutScheduledUpdateGroupAction",
                "autoscaling:PutScalingPolicy",
                "autoscaling:RegisterScalableTarget",
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricStatistics",
                "cloudwatch:PutMetricAlarm",
                "cloudwatch:DeleteAlarms",
                "sns:ListSubscriptions",
                "sns:ListTopics",
                "sns:Publish",
                "logs:DescribeLogStreams",
                "logs:GetLogEvents"
            ],
            "Resource": "*"
        }
    ]
}
