python - 如何将扩展策略添加到对流层的 cloudformation 中？

Question

我创建了一个 python 对流层脚本，总体运行良好。我刚刚添加了一段新代码，以将策略添加到警报的自动缩放组中。

代码如下:

tintScaleDown = autoscaling.ScalingPolicy("tintScaleDown1")
tintScaleDown.AdjustmentType = "ChangeInCapacity"
tintScaleDown.AutoScalingGroupName(Ref("tintASG"))
tintScaleDown.Cooldown = "900"
tintScaleDown.ScalingAdjustment = "1"
t.add_resource(tintScaleDown)

错误是:

回溯(最近一次调用最后一次): 文件“inPowered.py”，第 395 行，位于 TintScaleDown.AutoScalingGroupName(Ref("tintASG")) 文件“/usr/lib/python2.7/site-packages/troposphere/init.py”，第 79 行，getattr 引发 AttributeError(name)

引用应该已经在这一行中建立:

asg = autoscaling.AutoScalingGroup("tintASG")

CloudFormation 脚本的部分应如下所示:

            "tintScaleDown1": {
                    "Type": "AWS::AutoScaling::ScalingPolicy",
                    "Properties": {
            "AdjustmentType": "ChangeInCapacity",
                            "AutoScalingGroupName": {
                                    "Ref": "tintASG"
                            },
                            "Cooldown": "900",
                            "ScalingAdjustment": "-1"
                    }
    },

建议？

我会这样回答。

from troposphere import Template, autoscaling
t = Template() # Add the template object as "t"
#Create the Autoscaling object as "asg" within the creation of the object, call the template to make the template format
asg = t.add_resource(autoscaling.ScalingPolicy(
    "tintScaleDown1",
    AdjustmentType="ChangeInCapacity",
    AutoScalingGroupName=Ref(tintASG),
    Cooldon="900",
    ScalingAdjustment="-1",

))
print(t.to_json())
