--role-name
(string)
The name of the role to update with the new policy.
This parameter allows (through its regex pattern ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-
--policy-document
(string)
The policy that grants an entity permission to assume the role.
You must provide policies in JSON format in IAM. However, for CloudFormation templates formatted in YAML, you can provide the policy in JSON or YAML format. CloudFormation always converts a YAML policy to JSON format before submitting it to IAM.
The regex pattern used to validate this parameter is a string of characters consisting of the following:
- Any printable ASCII character ranging from the space character (
\u0020
) through the end of the ASCII character range- The printable characters in the Basic Latin and Latin-1 Supplement character set (through
\u00FF
)- The special characters tab (
\u0009
), line feed (\u000A
), and carriage return (\u000D
)
--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.
--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.
--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.
--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.
--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 update the trust policy for an IAM role
The following update-assume-role-policy
command updates the trust policy for the role named Test-Role
.
aws iam update-assume-role-policy \
--role-name Test-Role \
--policy-document file://Test-Role-Trust-Policy.json
This command produces no output.
The trust policy is defined as a JSON document in the Test-Role-Trust-Policy.json file. (The file name and extension do not have significance.) The trust policy must specify a principal.
To update the permissions policy for a role, use the put-role-policy
command.
For more information, see Creating IAM roles in the AWS IAM User Guide.
