Interface CfnSpotFleet.IInstanceRequirementsRequestProperty
The attributes for the instance types.
Namespace: Amazon.CDK.AWS.EC2
Assembly: Amazon.CDK.AWS.EC2.dll
Syntax (csharp)
public interface IInstanceRequirementsRequestProperty
Syntax (vb)
Public Interface IInstanceRequirementsRequestProperty
Remarks
When you specify instance attributes, Amazon EC2 will identify instance types with these attributes.
When you specify multiple attributes, you get instance types that satisfy all of the specified attributes. If you specify multiple values for an attribute, you get instance types that satisfy any of the specified values.
To limit the list of instance types from which Amazon EC2 can identify matching instance types, you can use one of the following parameters, but not both in the same request:
You must specify <code>VCpuCount</code> and <code>MemoryMiB</code> . All other attributes are optional. Any unspecified optional attribute is set to its default.
For more information, see Attribute-based instance type selection for EC2 Fleet , Attribute-based instance type selection for Spot Fleet , and Spot placement score in the Amazon EC2 User Guide .

Property Value
System.String[]
Remarks
All other instance types are ignored, even if they match your specified attributes.
You can use strings with one or more wild cards, represented by an asterisk ( ), to allow an instance type, size, or generation. The following are examples:
m5.8xlarge
, c5.
, m5a.
, r*
, 3
.
For example, if you specify c5*
,Amazon EC2 will allow the entire C5 instance family, which includes all C5a and C5n instance types. If you specify m5a.*
, Amazon EC2 will allow all the M5a instance types, but not the M5n instance types.

Property Value
System.Nullable<System.Double>
Remarks
This is the maximum you’ll pay for an On-Demand Instance, expressed as a percentage above the least expensive current generation M, C, or R instance type with your specified attributes. When Amazon EC2 selects instance types with your attributes, it excludes instance types priced above your threshold.
The parameter accepts an integer, which Amazon EC2 interprets as a percentage.
To turn off price protection, specify a high value, such as 999999
.
This parameter is not supported for GetSpotPlacementScores and GetInstanceTypesFromInstanceRequirements .
If you set TargetCapacityUnitType
to vcpu
