CreateActivation

Registers your on-premises server or virtual machine with Amazon EC2 so that you can manage these resources using Run Command. An on-premises server or virtual machine that has been registered with EC2 is called a managed instance. For more information about activations, see Setting Up AWS Systems Manager for Hybrid Environments.

Request Syntax

{ "DefaultInstanceName": "string", "Description": "string", "ExpirationDate": number, "IamRole": "string", "RegistrationLimit": number, "Tags": [ { "Key": "string", "Value": "string" } ] }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

DefaultInstanceName

The name of the registered, managed instance as it will appear in the Amazon EC2 console or when you use the AWS command line tools to list EC2 resources.

Tags

Optional metadata that you assign to a resource. Tags enable you to categorize a resource in different ways, such as by purpose, owner, or environment. For example, you might want to tag an activation to identify which servers or virtual machines (VMs) in your on-premises environment you intend to activate. In this case, you could specify the following key name/value pairs:

  • Key=OS,Value=Windows

  • Key=Environment,Value=Production

Important

When you install SSM Agent on your on-premises servers and VMs, you specify an activation ID and code. When you specify the activation ID and code, tags assigned to the activation are automatically applied to the on-premises servers or VMs.

You can't add tags to or delete tags from an existing activation. You can tag your on-premises servers and VMs after they connect to Systems Manager for the first time and are assigned a managed instance ID. This means they are listed in the AWS Systems Manager console with an ID that is prefixed with "mi-". For information about how to add tags to your managed instances, see AddTagsToResource. For information about how to remove tags from your managed instances, see RemoveTagsFromResource.

Type: Array of Tag objects

Array Members: Maximum number of 1000 items.

Required: No
