Interface CfnClusterCapacityProviderAssociations.CapacityProviderStrategyProperty

All Superinterfaces:

software.amazon.jsii.JsiiSerializable

All Known Implementing Classes:

Enclosing class:

CfnClusterCapacityProviderAssociations

@Stability(Stable)
public static interface CfnClusterCapacityProviderAssociations.CapacityProviderStrategyProperty
extends software.amazon.jsii.JsiiSerializable

The CapacityProviderStrategy property specifies the details of the default capacity provider strategy for the cluster.

When services or tasks are run in the cluster with no launch type or capacity provider strategy specified, the default capacity provider strategy is used.

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.ecs.*;
 CapacityProviderStrategyProperty capacityProviderStrategyProperty = CapacityProviderStrategyProperty.builder()
         .capacityProvider("capacityProvider")
         // the properties below are optional
         .base(123)
         .weight(123)
         .build();

Method Details

getCapacityProvider

@Stability(Stable)
@NotNull
String getCapacityProvider()

The short name of the capacity provider.

getBase

@Stability(Stable)
@Nullable
default Number getBase()

The base value designates how many tasks, at a minimum, to run on the specified capacity provider.

Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

getWeight

@Stability(Stable)
@Nullable
default Number getWeight()

The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider.

The weight value is taken into consideration after the base value, if defined, is satisfied.

If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.

An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .
