    • base

      @Stability(Stable) public CfnService.CapacityProviderStrategyItemProperty.Builder base(Number base)
      Sets the value of CfnService.CapacityProviderStrategyItemProperty.getBase()
      Parameters:
      base - 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
      • Default value is 0 if not specified
      • Valid range: 0 to 100,000
      • Base requirements are satisfied first before weight distribution
      Returns:
      this

    • capacityProvider

      @Stability(Stable) public CfnService.CapacityProviderStrategyItemProperty.Builder capacityProvider(String capacityProvider)
      Sets the value of CfnService.CapacityProviderStrategyItemProperty.getCapacityProvider()
      Parameters:
      capacityProvider - The short name of the capacity provider.
      Returns:
      this

    • weight

      @Stability(Stable) public CfnService.CapacityProviderStrategyItemProperty.Builder weight(Number weight)
      Sets the value of CfnService.CapacityProviderStrategyItemProperty.getWeight()
      Parameters:
      weight - 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
      • Default value is 0 if not specified
      • Valid range: 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:

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

      Returns:
      this
