Create Capacity Reservation
ec2_create_capacity_reservation | R Documentation |
Creates a new Capacity Reservation with the specified attributes¶
Description¶
Creates a new Capacity Reservation with the specified attributes.
Capacity Reservations enable you to reserve capacity for your Amazon EC2 instances in a specific Availability Zone for any duration. This gives you the flexibility to selectively add capacity reservations and still get the Regional RI discounts for that usage. By creating Capacity Reservations, you ensure that you always have access to Amazon EC2 capacity when you need it, for as long as you need it. For more information, see Capacity Reservations in the Amazon EC2 User Guide.
Your request to create a Capacity Reservation could fail if Amazon EC2 does not have sufficient capacity to fulfill the request. If your request fails due to Amazon EC2 capacity constraints, either try again at a later time, try in a different Availability Zone, or request a smaller capacity reservation. If your application is flexible across instance types and sizes, try to create a Capacity Reservation with different instance attributes.
Your request could also fail if the requested quantity exceeds your On-Demand Instance limit for the selected instance type. If your request fails due to limit constraints, increase your On-Demand Instance limit for the required instance type and try again. For more information about increasing your instance limits, see Amazon EC2 Service Quotas in the Amazon EC2 User Guide.
Usage¶
ec2_create_capacity_reservation(ClientToken, InstanceType,
InstancePlatform, AvailabilityZone, AvailabilityZoneId, Tenancy,
InstanceCount, EbsOptimized, EphemeralStorage, EndDate, EndDateType,
InstanceMatchCriteria, TagSpecifications, DryRun, OutpostArn,
PlacementGroupArn)
Arguments¶
ClientToken
Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see Ensure Idempotency.
InstanceType
[required] The instance type for which to reserve capacity. For more information, see Instance types in the Amazon EC2 User Guide.
InstancePlatform
[required] The type of operating system for which to reserve capacity.
AvailabilityZone
The Availability Zone in which to create the Capacity Reservation.
AvailabilityZoneId
The ID of the Availability Zone in which to create the Capacity Reservation.
Tenancy
Indicates the tenancy of the Capacity Reservation. A Capacity Reservation can have one of the following tenancy settings:
default
- The Capacity Reservation is created on hardware that is shared with other Amazon Web Services accounts.dedicated
- The Capacity Reservation is created on single-tenant hardware that is dedicated to a single Amazon Web Services account.
InstanceCount
[required] The number of instances for which to reserve capacity.
Valid range: 1 - 1000
EbsOptimized
Indicates whether the Capacity Reservation supports EBS-optimized instances. This optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal I/O performance. This optimization isn't available with all instance types. Additional usage charges apply when using an EBS- optimized instance.
EphemeralStorage
Deprecated.
EndDate
The date and time at which the Capacity Reservation expires. When a Capacity Reservation expires, the reserved capacity is released and you can no longer launch instances into it. The Capacity Reservation's state changes to
expired
when it reaches its end date and time.You must provide an
EndDate
value ifEndDateType
islimited
. OmitEndDate
ifEndDateType
isunlimited
.If the
EndDateType
islimited
, the Capacity Reservation is cancelled within an hour from the specified time. For example, if you specify 5/31/2019, 13:30:55, the Capacity Reservation is guaranteed to end between 13:30:55 and 14:30:55 on 5/31/2019.EndDateType
Indicates the way in which the Capacity Reservation ends. A Capacity Reservation can have one of the following end types:
unlimited
- The Capacity Reservation remains active until you explicitly cancel it. Do not provide anEndDate
if theEndDateType
isunlimited
.limited
- The Capacity Reservation expires automatically at a specified date and time. You must provide anEndDate
value if theEndDateType
value islimited
.
InstanceMatchCriteria
Indicates the type of instance launches that the Capacity Reservation accepts. The options include:
open
- The Capacity Reservation automatically matches all instances that have matching attributes (instance type, platform, and Availability Zone). Instances that have matching attributes run in the Capacity Reservation automatically without specifying any additional parameters.targeted
- The Capacity Reservation only accepts instances that have matching attributes (instance type, platform, and Availability Zone), and explicitly target the Capacity Reservation. This ensures that only permitted instances can use the reserved capacity.
Default:
open
TagSpecifications
The tags to apply to the Capacity Reservation during launch.
DryRun
Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is
DryRunOperation
. Otherwise, it isUnauthorizedOperation
.OutpostArn
The Amazon Resource Name (ARN) of the Outpost on which to create the Capacity Reservation.
PlacementGroupArn
The Amazon Resource Name (ARN) of the cluster placement group in which to create the Capacity Reservation. For more information, see Capacity Reservations for cluster placement groups in the Amazon EC2 User Guide.
