Properties
Field
The field to apply the placement strategy against.
virtual string Field { get; }
Property Value
System.String
Remarks
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.
Type
The type of placement strategy.
string Type { get; }
Property Value
System.String
Remarks
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.
