Interface CfnCluster.ICapacityProviderStrategyItemProperty
The CapacityProviderStrategyItem
property specifies the details of the default capacity provider strategy for the cluster.
Namespace: Amazon.CDK.AWS.ECS
Assembly: Amazon.CDK.AWS.ECS.dll
Syntax (csharp)
public interface ICapacityProviderStrategyItemProperty
Syntax (vb)
Public Interface ICapacityProviderStrategyItemProperty
Remarks
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.

Synopsis
Properties
Base | The base value designates how many tasks, at a minimum, to run on the specified capacity provider. |
CapacityProvider | The short name of the capacity provider. |
Weight | The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. |
Properties
Base
The base value designates how many tasks, at a minimum, to run on the specified capacity provider.
virtual Nullable<double> Base { get; }
Property Value
System.Nullable<System.Double>
Remarks
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.
CapacityProvider
The short name of the capacity provider.
virtual string CapacityProvider { get; }
Property Value
System.String
Remarks
Weight
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider.
virtual Nullable<double> Weight { get; }
Property Value
System.Nullable<System.Double>
Remarks
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 .
