Synopsis

Calls the Amazon Elastic Compute Cloud (EC2) TerminateInstances API operation.

Syntax

Remove-EC2Instance
-InstanceId <Object[]>
-Select <String>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

Shuts down the specified instances. This operation is idempotent; if you terminate an instance more than once, each call succeeds. If you specify multiple instances and the request fails (for example, because of a single incorrect instance ID), none of the instances are terminated. Terminated instances remain visible after termination (for approximately one hour). By default, Amazon EC2 deletes all EBS volumes that were attached when the instance launched. Volumes attached after instance launch continue running. You can stop, start, and terminate EBS-backed instances. You can only terminate instance store-backed instances. What happens to an instance differs if you stop it or terminate it. For example, when you stop an instance, the root device and any other devices attached to the instance persist. When you terminate an instance, any attached EBS volumes with the DeleteOnTermination block device mapping parameter set to true are automatically deleted. For more information about the differences between stopping and terminating instances, see Instance Lifecycle in the Amazon Elastic Compute Cloud User Guide. For more information about troubleshooting, see Troubleshooting Terminating Your Instance in the Amazon Elastic Compute Cloud User Guide.

Parameters

This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-InstanceId <Object[]>
The IDs of the instances.Constraints: Up to 1000 instance IDs. We recommend breaking up this request into smaller batches.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
AliasesInstanceIds
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the InstanceId parameter. The -PassThru parameter is deprecated, use -Select '^InstanceId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'TerminatingInstances'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.EC2.Model.TerminateInstancesResponse). Specifying the name of a property of type Amazon.EC2.Model.TerminateInstancesResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

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?True (ByPropertyName)
AliasesAK
-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?True (ByValue, ByPropertyName)
-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?True (ByPropertyName)
-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?True (ByValue, ByPropertyName)
-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.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?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-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?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRegionToCall
-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?True (ByPropertyName)
AliasesSK, SecretAccessKey
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesST

Outputs

This cmdlet returns a collection of Amazon.EC2.Model.InstanceStateChange objects. The service call response (type Amazon.EC2.Model.TerminateInstancesResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

Examples

Example 1

PS C:\> Remove-EC2Instance -InstanceId i-12345678

CurrentState InstanceId PreviousState
------------ ---------- -------------
Amazon.EC2.Model.InstanceState i-12345678 Amazon.EC2.Model.InstanceState
This example terminates the specified instance (the instance may be running or in 'stopped' state).
The cmdlet will prompt for confirmation before proceeding; use the -Force switch to suppress the prompt.
