/AWS1/CL_ECSCAPPVDRSTRAGITEM

The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTaskor CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateClusterCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.

With FARGATE_SPOT, you can run interruption tolerant tasks at a rate that's discounted compared to the FARGATE price. FARGATE_SPOT runs tasks on spare compute capacity. When Amazon Web Services needs the capacity back, your tasks are interrupted with a two-minute warning. FARGATE_SPOT supports Linux tasks with the X86_64 architecture on platform version 1.3.0 or later. FARGATE_SPOT supports Linux tasks with the ARM64 architecture on platform version 1.4.0 or later.

A capacity provider strategy can contain a maximum of 20 capacity providers.

CONSTRUCTOR

IMPORTING

Required arguments:

iv_capacityprovider TYPE /AWS1/ECSSTRING /AWS1/ECSSTRING

The short name of the capacity provider.

Optional arguments:

iv_weight TYPE /AWS1/ECSCAPPVDRSTRAGITEMWT /AWS1/ECSCAPPVDRSTRAGITEMWT

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.

Weight value characteristics:

• Weight is considered after the base value is satisfied

• The default value is 0 if not specified

• The valid range is 0 to 1,000

• At least one capacity provider must have a weight greater than zero

• Capacity providers with weight of 0 cannot place tasks

Task distribution logic:

1. Base satisfaction: The minimum number of tasks specified by the base value are placed on that capacity provider

2. Weight distribution: After base requirements are met, additional tasks are distributed according to weight ratios

Examples:

Equal Distribution: Two capacity providers both with weight 1 will split tasks evenly after base requirements are met.

Weighted Distribution: If capacityProviderA has weight 1 and capacityProviderB has weight 4, then for every 1 task on A, 4 tasks will run on B.

iv_base TYPE /AWS1/ECSCAPPVDRSTRAGITEMBASE /AWS1/ECSCAPPVDRSTRAGITEMBASE

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

Base value characteristics:

• Only one capacity provider in a strategy can have a base defined

• The default value is 0 if not specified

• The valid range is 0 to 100,000

• Base requirements are satisfied first before weight distribution
