min_ready_instances typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable] Property minReadyInstances: Minimum number of surviving instances.
scaling_rule_enable typing.Union[bool, ros_cdk_core.IResolvable] Property scalingRuleEnable: Whether to enable the scaling rule.
scaling_rule_metric typing.Union[ros_cdk_core.IResolvable, ScalingRuleMetricProperty] Property scalingRuleMetric: Configuration of monitoring indicator elasticity policy.
scaling_rule_timer typing.Union[ros_cdk_core.IResolvable, ScalingRuleTimerProperty] Property scalingRuleTimer: The configuration of the timer scaling policy.

app_idRequired 

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

Property appId: The ID of the application.

scaling_rule_nameRequired 

scaling_rule_name: typing.Union[str, IResolvable]
  • 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_typeRequired 

scaling_rule_type: typing.Union[str, IResolvable]
  • 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_ratioOptional 

min_ready_instance_ratio: typing.Union[typing.Union[int, float], IResolvable]
  • 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_instancesOptional 

min_ready_instances: typing.Union[typing.Union[int, float], IResolvable]
  • 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_enableOptional 

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

Property scalingRuleEnable: Whether to enable the scaling rule.

scaling_rule_metricOptional 

scaling_rule_metric: typing.Union[IResolvable, ScalingRuleMetricProperty]

Property scalingRuleMetric: Configuration of monitoring indicator elasticity policy.

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

scaling_rule_timerOptional 

scaling_rule_timer: typing.Union[IResolvable, ScalingRuleTimerProperty]

Property scalingRuleTimer: The configuration of the timer scaling policy.
