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.

---

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

Property scalingRuleTimer: The configuration of the timer scaling policy.

---

to_string

def to_string() -> str

Returns a string representation of this construct.

synthesize

def add_dependency(
  resource: Resource
) -> None

resource^Required

• Type: ros_cdk_core.Resource

---
