Struct rusoto_ecs::CapacityProviderStrategyItem [−][src]
pub struct CapacityProviderStrategyItem { pub base: Option<i64>, pub capacity_provider: String, pub weight: Option<i64>, }
Expand description
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or 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 CreateCapacityProvider API operation.
To use a AWS Fargate capacity provider, specify either the FARGATE
or FARGATE_SPOT
capacity providers. The AWS 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.
Fields
base: Option<i64>
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.
capacity_provider: String
The short name of the capacity provider.
weight: Option<i64>
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
will not 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 is run using capacityProviderA, four tasks would use capacityProviderB.
