什么是Fargate的LaunchConfiguration？ [英] What LaunchConfiguration for Fargate?

问题描述

AutoScalingGroup需要启动配置

An AutoScalingGroup needs a LaunchConfiguration

问题是启动配置需要ImageId和其他参数（自从我使用容器以来就没有）。

The problem is that the LaunchConfiguration requires things like ImageId and other parameters which I do not have since I am using containers.

使用ECS Fargate时应如何配置LaunchConfiguration？

How should the LaunchConfiguration be configured when using ECS Fargate?

推荐答案

这是FARGATE的有效示例自动缩放策略可以看到，既不涉及启动配置也不涉及Auto Scaling组。您只需要插入 ScalingTargetId ，由于我们将使用目标跟踪扩展策略，因此基础架构将使您拥有一个目标最大为80％的系统CPU使用率。当使用率超过此值时，将发生自动缩放。

This is a working example of a FARGATE autoscaling policy, that, as you can see, does not involve Launch Configuration nor Auto Scaling Groups. You just have to insert the ScalingTargetId, and since we'll be using a Target Tracking Scaling Policy, the infrastructure will grant you to have a system with a target of 80% maximum CPU usage. When the usage will be more than that, autoscaling will occur.

ExampleCPUAutoScalingPolicy:
  Type: AWS::ApplicationAutoScaling::ScalingPolicy
  Properties:
    PolicyName: ECSCPUAutoScalingPolicy
    PolicyType: TargetTrackingScaling
    ScalingTargetId: !Ref ECSTarget
    TargetTrackingScalingPolicyConfiguration:
      DisableScaleIn: false
      TargetValue: 80
      ScaleInCooldown: 60
      ScaleOutCooldown: 60
      PredefinedMetricSpecification:
        PredefinedMetricType: ECSServiceAverageCPUUtilization
