public final PlacementStrategyType type()
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).
If the service returns an enum value that is not available in the current SDK version, type
will return
PlacementStrategyType.UNKNOWN_TO_SDK_VERSION
. The raw value returned by the service is available from
typeAsString()
.

PlacementStrategyType
public final String field()
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.
