aws ec2 request-spot-instances
Creates a Spot Instance request. For more information, see Spot Instance requests in the Amazon EC2 User Guide for Linux Instances
Options
| Name | Description |
|---|---|
--availability-zone-group <string> | The user-specified name for a logical grouping of requests. When you specify an Availability Zone group in a Spot Instance request, all Spot Instances in the request are launched in the same Availability Zone. Instance proximity is maintained with this parameter, but the choice of Availability Zone is not. The group applies only to requests for Spot Instances of the same instance type. Any additional Spot Instance requests that are specified with the same Availability Zone group name are launched in that same Availability Zone, as long as at least one instance from the group is still active. If there is no active instance running in the Availability Zone group that you specify for a new Spot Instance request (all instances are terminated, the request is expired, or the maximum price you specified falls below current Spot price), then Amazon EC2 launches the instance in any Availability Zone where the constraint can be met. Consequently, the subsequent set of Spot Instances could be placed in a different zone from the original request, even if you specified the same Availability Zone group. Default: Instances are launched in any available Availability Zone |
--block-duration-minutes <integer> | The required duration for the Spot Instances (also known as Spot blocks), in minutes. This value must be a multiple of 60 (60, 120, 180, 240, 300, or 360). The duration period starts as soon as your Spot Instance receives its instance ID. At the end of the duration period, Amazon EC2 marks the Spot Instance for termination and provides a Spot Instance termination notice, which gives the instance a two-minute warning before it terminates. You can't specify an Availability Zone group or a launch group if you specify a duration. New accounts or accounts with no previous billing history with AWS are not eligible for Spot Instances with a defined duration (also known as Spot blocks) |
--client-token <string> | Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see How to Ensure Idempotency in the Amazon EC2 User Guide for Linux Instances |
--dry-run | 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 is UnauthorizedOperation |
--no-dry-run | 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 is UnauthorizedOperation |
--instance-count <integer> | The maximum number of Spot Instances to launch. Default: 1 |
--launch-group <string> | The instance launch group. Launch groups are Spot Instances that launch together and terminate together. Default: Instances are launched and terminated individually |
--launch-specification <structure> | The launch specification |
--spot-price <string> | The maximum price per hour that you are willing to pay for a Spot Instance. The default is the On-Demand price |
--type <string> | The Spot Instance request type. Default: one-time |
--valid-from <timestamp> | The start date of the request. If this is a one-time request, the request becomes active at this date and time and remains active until all instances launch, the request expires, or the request is canceled. If the request is persistent, the request becomes active at this date and time and remains active until it expires or is canceled. The specified start date and time cannot be equal to the current date and time. You must specify a start date and time that occurs after the current date and time |
--valid-until <timestamp> | The end date of the request, in UTC format (YYYY-MM-DDTHH:MM:SSZ). For a persistent request, the request remains active until the ValidUntil date and time is reached. Otherwise, the request remains active until you cancel it. For a one-time request, the request remains active until all instances launch, the request is canceled, or the ValidUntil date and time is reached. By default, the request is valid for 7 days from the date the request was created |
--tag-specifications <list> | The key-value pair for tagging the Spot Instance request on creation. The value for ResourceType must be spot-instances-request, otherwise the Spot Instance request fails. To tag the Spot Instance request after it has been created, see CreateTags |
--instance-interruption-behavior <string> | The behavior when a Spot Instance is interrupted. The default is terminate |
--cli-input-json <string> | Performs service operation based on the JSON string provided. The JSON string follows the format provided by ``--generate-cli-skeleton``. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally |
--generate-cli-skeleton <string> | Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value ``input``, prints a sample input JSON that can be used as an argument for ``--cli-input-json``. If provided with the value ``output``, it validates the command inputs and returns a sample output JSON for that command |
