)

scope^Required

• Type: ros_cdk_core.Construct

id^Required

• Type: str

app_id^Required

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property appId: The ID of the application.

scaling_rule_name^Required

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property scalingRuleName: The name of the auto scaling policy.

The name must start with a lowercase letter, and can contain lowercase letters, digits, and hyphens (-).The name must be 1 to 32 characters in length.

scaling_rule_type^Required

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property scalingRuleType: The type of the auto scaling policy.

Valid values: timer: Timed scaling. metric: Custom metric scaling.mix: mix scaling

min_ready_instance_ratio^Optional

• Type: typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable]

Property minReadyInstanceRatio: The minimum percentage of surviving instances.

The value description is as follows:-1: Initialization value, indicating that the percentage is not used.0~100: The unit is a percentage, rounded up. For example, if it is set to 50%, if there are currently 5 instances, the minimum number of surviving instances is 3.

min_ready_instances^Optional

• Type: typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable]

Property minReadyInstances: Minimum number of surviving instances.

The value is as follows:If set to 0, the application will be interrupted during the upgrade process.If set to -1, the minimum number of surviving instances will use the system recommended value, which is 25% of the existing number of instances. If there are currently 5 instances, 5×25%=1.25, after rounding up, the minimum number of surviving instances is 2.

scaling_rule_enable^Optional

• Type: typing.Union[bool, ros_cdk_core.IResolvable]

Property scalingRuleEnable: Whether to enable the scaling rule.

scaling_rule_metric^Optional

• Type: typing.Union[ros_cdk_core.IResolvable, ScalingRuleMetricProperty]

Property scalingRuleMetric: Configuration of monitoring indicator elasticity policy.

This parameter is required when you select monitoring indicator elasticity policy setting.

scaling_rule_timer^Optional

• Type: typing.Union[ros_cdk_core.IResolvable, ScalingRuleTimerProperty]

Property scalingRuleTimer: The configuration of the timer scaling policy.

enable_resource_property_constraint^Optional

• Type: bool

Methods

to_string

def to_string() -> str

Returns a string representation of this construct.

synthesize

def synthesize(
  session: ISynthesisSession
) -> None

Allows this construct to emit artifacts into the cloud assembly during synthesis.

This method is usually implemented by framework-level constructs such as Stack and Asset as they participate in synthesizing the cloud assembly.

session^Required

• Type: ros_cdk_core.ISynthesisSession

The synthesis session.

add_condition

def add_condition(
  condition: RosCondition
) -> None

condition^Required

• Type: ros_cdk_core.RosCondition

add_count

def add_count(
  count: typing.Union[typing.Union[int, float], IResolvable]
) -> None

count^Required

• Type: typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable]

add_dependency

def add_dependency(
  resource: Resource
) -> None

resource^Required

• Type: ros_cdk_core.Resource

add_resource_desc

def add_resource_desc(
  desc: str
) -> None

desc^Required

• Type: str

apply_removal_policy

def apply_removal_policy(
  policy: RemovalPolicy
) -> None

policy^Required

• Type: ros_cdk_core.RemovalPolicy

fetch_condition

def fetch_condition() -> RosCondition

fetch_dependency

def fetch_dependency() -> typing.List[str]

fetch_resource_desc

def fetch_resource_desc() -> str

get_att

def get_att(
  name: str
) -> IResolvable

name^Required

• Type: str

set_metadata

def set_metadata(
  key: str,
  value: typing.Any
) -> None

key^Required

• Type: str

value^Required

• Type: typing.Any

Static Functions

is_construct

import ros_cdk_sae
ros_cdk_sae.ApplicationScalingRule.is_construct(
  x: typing.Any
)

Return whether the given object is a Construct.

x^Required

• Type: typing.Any

Properties

node^Required

node: ConstructNode

• Type: ros_cdk_core.ConstructNode

The construct tree node associated with this construct.

env^Required

env: IResourceEnvironment

• Type: ros_cdk_core.IResourceEnvironment

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

stack: Stack

• Type: ros_cdk_core.Stack

The stack in which this resource is defined.

resource^Optional

resource: RosResource

attr_scaling_rule_name: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Attribute ScalingRuleName: The name of the scaling rule.

props^Required

props: ApplicationScalingRuleProps
