Question

我创建了一个python对流层脚本，整体上运行得非常好。我刚刚添加了一段新代码，用于向自动缩放组添加策略以发出警报。

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：

追踪（最近一次通话）：文件“inPowered.py”，第395行，in tintScaleDown.AutoScalingGroupName（参考文献（ “tintASG”））文件“/usr/lib/python2.7/site-packages/troposphere/init.py”，第79行， getattr 引发AttributeError（名称）

参考文献应该在这一行中建立：

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？

Answer 1

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())

Answer 2

好的，所以对流层的创造者Mark Peek指出我的语法不正确。解决方案是

tintScaleDown.AutoScalingGroupName(Ref("tintASG"))

应该是

tintScaleDown.AutoScalingGroupName = Ref("tintASG")

如何在对流层的cloudformation中添加扩展策略？
