Description
Creates a Spot Instance request.
For more information, see Spot Instance Requests in the Amazon EC2 User Guide for Linux Instances.
Parameters
-AvailabilityZoneGroup <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.

-BlockDurationMinute <Int32>
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.

Common Credential and Region Parameters
-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key
if the corresponding session token is supplied to the -SessionToken parameter.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information,
and optionally a token for session-based credentials.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)
If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.
If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.
As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing
credential information. The profile is expected to be found in the secure credential
file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also
specify the name of a profile stored in the .ini-format credential file used with
the AWS CLI and other AWS SDKs.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile.
Contains the network credentials to be supplied during authentication with the
configured identity provider's endpoint. This parameter is not required if the
user's default network identity can or should be used during authentication.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key
if the corresponding session token is supplied to the -SessionToken parameter.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-SessionToken <String>
The session token if the access and secret keys are temporary session-based
credentials.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-EndpointUrl <String>
The endpoint to make the call against.
Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
Inputs
You can pipe a String object to this cmdlet for the SpotPrice parameter.
Outputs
This cmdlet returns a collection of Amazon.EC2.Model.SpotInstanceRequest objects.
The service call response (type Amazon.EC2.Model.RequestSpotInstancesResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
