tb_pulumi.autoscale¶

Infrastructural patterns related to AWS Application Autoscaling.

class tb_pulumi.autoscale.EcsServiceAutoscaler(name: str, project: ThunderbirdPulumiProject, service: Service, cpu_threshold: int = 70, cooldown: int = 300, disable_scale_in: bool = False, max_capacity: int = 2, min_capacity: int = 1, ram_threshold: int = 70, suspend: bool = False, opts: ResourceOptions = None, **kwargs)¶

Bases: ThunderbirdComponentResource

Pulumi Type: tb:autoscale:EcsServiceAutoscaler

Builds an autoscaler for an ECS Service.

Produces the following resources:

cpu_policy - The aws.appautoscaling.Policy tracking average CPU usage.

ram_policy - The aws.appautoscaling.Policy tracking average memory usage.

target - The aws.appautoscaling.Target describing the service and scaling settings.

Parameters:

name (str) – A string identifying this set of resources.
project (tb_pulumi.ThunderbirdPulumiProject) – The ThunderbirdPulumiProject to add these resources to.
service (aws.ecs.Service) – The aws.ecs.Service to build this autoscaler for.
cpu_threshold (int, optional) – Point at which we scale based on the average CPU consumption across service containers. Defaults to 70.
cooldown (int, optional) – Number of seconds to wait between scaling events, used to prevent rapid fluctuations in capacity. Defaults to 300.
disable_scale_in (bool, optional) – When True, prevents the cluster from scaling in while still allowing scale-outs. Defaults to False.
max_capacity (int, optional) – Maximum number of containers to run in the cluster. Defaults to 2.
min_capacity (int, optional) – Minimum number of containers to run in the cluster. Defaults to 1.
ram_threshold (int, optional) – Point at which we scale based on the average memory usage across service containers. Defaults to 70.
suspend (bool, optional) – When True, suspends all scaling operations. Defaults to False.
opts (pulumi.ResourceOptions, optional) – Additional pulumi.ResourceOptions to apply to these resources. Defaults to None.
kwargs – Any other keyword arguments which will be passed as inputs to the ThunderbirdComponentResource superconstructor.
