Struct rusoto_ecs::PlacementStrategy [−][src]
Expand description
The task placement strategy for a task or service. For more information, see Task Placement Strategies in the Amazon Elastic Container Service Developer Guide.
Fields
field: Option<String>
The field to apply the placement strategy against. For the spread
placement strategy, valid values are instanceId
(or host
, which has the same effect), or any platform or custom attribute that is applied to a container instance, such as attribute:ecs.availability-zone
. For the binpack
placement strategy, valid values are cpu
and memory
. For the random
placement strategy, this field is not used.
type_: Option<String>
The type of placement strategy. The random
placement strategy randomly places tasks on available candidates. The spread
placement strategy spreads placement across available candidates evenly based on the field
parameter. The binpack
strategy places tasks on available candidates that have the least available amount of the resource that is specified with the field
parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory (but still enough to run the task).
