Instance Attribute Details

#field ⇒ 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’s 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.

Returns:

# File 'lib/aws-sdk-ecs/types.rb', line 9832

class PlacementStrategy < Struct.new(
  :type,
  :field)
  SENSITIVE = []
  include Aws::Structure
end

#type ⇒ 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’s 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.

Returns:

# File 'lib/aws-sdk-ecs/types.rb', line 9832

class PlacementStrategy < Struct.new(
  :type,
  :field)
  SENSITIVE = []
  include Aws::Structure
