AWS CLI Command Reference

[ aws . sts ]

assume-root

Description

Returns a set of short term credentials you can use to perform privileged tasks in a member account.

Before you can launch a privileged session, you must have enabled centralized root access in your organization. For steps to enable this feature, see Centralize root access for member accounts in the IAM User Guide .

Note

The global endpoint is not supported for AssumeRoot. You must send this request to a Regional STS endpoint. For more information, see Endpoints .

You can track AssumeRoot in CloudTrail logs to determine what actions were performed in a session. For more information, see Track privileged tasks in CloudTrail in the IAM User Guide .

Options

--target-principal (string)

The member account principal ARN or account ID.

--task-policy-arn (structure)

The identity based policy that scopes the session to the privileged tasks that can be performed. You can use one of following Amazon Web Services managed policies to scope root session actions. You can add additional customer managed policies to further limit the permissions for the root session.

arn -> (string)

The Amazon Resource Name (ARN) of the IAM managed policy to use as a session policy for the role. For more information about ARNs, see Amazon Resource Names (ARNs) and Amazon Web Services Service Namespaces in the Amazon Web Services General Reference .

Shorthand Syntax:

arn=string

JSON Syntax:

{
  "arn": "string"
}

--duration-seconds (integer)

The duration, in seconds, of the privileged session. The value can range from 0 seconds up to the maximum session duration of 900 seconds (15 minutes). If you specify a value higher than this setting, the operation fails.

By default, the value is set to 900 seconds.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

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. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--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.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Output

Credentials -> (structure)

The temporary security credentials, which include an access key ID, a secret access key, and a security token.

Note

The size of the security token that STS API operations return is not fixed. We strongly recommend that you make no assumptions about the maximum size.

AccessKeyId -> (string)

The access key ID that identifies the temporary security credentials.

SecretAccessKey -> (string)

The secret access key that can be used to sign requests.

SessionToken -> (string)

The token that users must pass to the service API to use the temporary credentials.

Expiration -> (timestamp)

The date on which the current credentials expire.

SourceIdentity -> (string)

The source identity specified by the principal that is calling the AssumeRoot operation.

You can use the aws:SourceIdentity condition key to control access based on the value of source identity. For more information about using source identity, see Monitor and control actions taken with assumed roles in the IAM User Guide .

The regex used to validate this parameter is a string of characters consisting of upper- and lower-case alphanumeric characters with no spaces. You can also include underscores or any of the following characters: =,.@-
