Describes details about the activation, such as the date and time the activation was created, its expiration date, the Identity and Access Management (IAM) role assigned to the managed nodes in the activation, and the number of nodes registered by using this activation.

See also: AWS API Documentation

describe-activations is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: ActivationList


[--filters <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--endpoint-url <value>]
[--output <value>]
[--query <value>]
[--profile <value>]
[--region <value>]
[--version <value>]
[--color <value>]
[--ca-bundle <value>]
[--cli-read-timeout <value>]
[--cli-connect-timeout <value>]


--filters (list)

A filter to view information about your activations.


Filter for the DescribeActivation API.

FilterKey -> (string)

The name of the filter.

FilterValues -> (list)

The filter values.


Shorthand Syntax:

FilterKey=string,FilterValues=string,string ...

JSON Syntax:

    "FilterKey": "ActivationIds"|"DefaultInstanceName"|"IamRole",
    "FilterValues": ["string", ...]

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.



To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To describe activations

The following describe-activations example lists details about the activations in your AWS account.

aws ssm describe-activations

For more information, see Step 4: Create a Managed-Instance Activation for a Hybrid Environment in the AWS Systems Manager User Guide.


ActivationList -> (list)

A list of activations for your Amazon Web Services account.


An activation registers one or more on-premises servers or virtual machines (VMs) with Amazon Web Services so that you can configure those servers or VMs using Run Command. A server or VM that has been registered with Amazon Web Services Systems Manager is called a managed node.

ActivationId -> (string)

The ID created by Systems Manager when you submitted the activation.

Description -> (string)

A user defined description of the activation.

DefaultInstanceName -> (string)

A name for the managed node when it is created.

IamRole -> (string)

The Identity and Access Management (IAM) role to assign to the managed node.

RegistrationLimit -> (integer)

The maximum number of managed nodes that can be registered using this activation.

RegistrationsCount -> (integer)

The number of managed nodes already registered with this activation.

ExpirationDate -> (timestamp)

The date when this activation can no longer be used to register managed nodes.

Expired -> (boolean)

Whether or not the activation is expired.

CreatedDate -> (timestamp)

The date the activation was created.

Tags -> (list)

Tags assigned to the activation.


Metadata that you assign to your Amazon Web Services resources. Tags enable you to categorize your resources in different ways, for example, by purpose, owner, or environment. In Amazon Web Services Systems Manager, you can apply tags to Systems Manager documents (SSM documents), managed nodes, maintenance windows, parameters, patch baselines, OpsItems, and OpsMetadata.

Key -> (string)

The name of the tag.

Value -> (string)

The value of the tag.

NextToken -> (string)

The token for the next set of items to return. Use this token to get the next set of results.
