Examples

// The code below shows an example of how to instantiate this type.
            // The values are placeholders you should change.
            using Amazon.CDK.AWS.AutoScaling;
            using Amazon.CDK.AWS.EC2;

            InstanceType instanceType;
            LaunchTemplate launchTemplate;

            var launchTemplateOverrides = new LaunchTemplateOverrides {
                InstanceType = instanceType,

                // the properties below are optional
                LaunchTemplate = launchTemplate,
                WeightedCapacity = 123
            };

Properties

InstanceType

The instance type, such as m3.xlarge. You must use an instance type that is supported in your requested Region and Availability Zones.

InstanceType InstanceType { get; }

Property Value

InstanceType

Remarks

Default: - Do not override instance type

LaunchTemplate

Provides the launch template to be used when launching the instance type.

ILaunchTemplate? LaunchTemplate { get; }

Property Value

ILaunchTemplate

Remarks

For example, some instance types might require a launch template with a different AMI. If not provided, Amazon EC2 Auto Scaling uses the launch template that's defined for your mixed instances policy.

Default: - Do not override launch template

WeightedCapacity

The number of capacity units provided by the specified instance type in terms of virtual CPUs, memory, storage, throughput, or other relative performance characteristic.

double? WeightedCapacity { get; }

Property Value

double?

Remarks

When a Spot or On-Demand Instance is provisioned, the capacity units count toward the desired capacity. Amazon EC2 Auto Scaling provisions instances until the desired capacity is totally fulfilled, even if this results in an overage. Value must be in the range of 1 to 999.

For example, If there are 2 units remaining to fulfill capacity, and Amazon EC2 Auto Scaling can only provision an instance with a WeightedCapacity of 5 units, the instance is provisioned, and the desired capacity is exceeded by 3 units.

Default: - Do not provide weight
