get-context-keys-for-principal-policy

Description

Gets a list of all of the context keys referenced in all the IAM policies that are attached to the specified IAM entity. The entity can be an IAM user, group, or role. If you specify a user, then the request also includes all of the policies attached to groups that the user is a member of.

You can optionally include a list of one or more additional policies, specified as strings. If you want to include only a list of policies by string, use GetContextKeysForCustomPolicy instead.

Note: This operation discloses information about the permissions granted to other users. If you do not want users to see other user's permissions, then consider allowing them to use GetContextKeysForCustomPolicy instead.

Context keys are variables maintained by Amazon Web Services and its services that provide details about the context of an API query request. Context keys can be evaluated by testing against a value in an IAM policy. Use GetContextKeysForPrincipalPolicy to understand what key names and values you must supply when you call SimulatePrincipalPolicy .

Options

--policy-source-arn (string)

The ARN of a user, group, or role whose policies contain the context keys that you want listed. If you specify a user, the list includes context keys that are found in all policies that are attached to the user. The list also includes all groups that the user is a member of. If you pick a group or a role, then it includes only those context keys that are found in policies attached to that entity. Note that all parameters are shown in unencoded form here for clarity, but must be URL encoded to be included as a part of a real HTML request.

For more information about ARNs, see Amazon Resource Names (ARNs) in the Amazon Web Services General Reference .

--policy-input-list (list)

An optional list of additional policies for which you want the list of context keys that are referenced.

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 )

(string)

Syntax:

"string" "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.

--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. 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

--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.

Examples

Note

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 list the context keys referenced by all policies associated with an IAM principal

The following get-context-keys-for-principal-policy command retrieves all policies that are attached to the user saanvi and any groups she is a member of. It then parses each and lists the context keys used by those policies. Use this command to identify which context key values you must supply to successfully use the simulate-custom-policy and simulate-principal-policy commands. You can also retrieve the list of context keys used by an arbitrary JSON policy by using the get-context-keys-for-custom-policy command.

aws iam get-context-keys-for-principal-policy \
   --policy-source-arn arn:aws:iam::123456789012:user/saanvi

Output:

{
    "ContextKeyNames": [
        "aws:username",
        "aws:CurrentTime"
    ]
}

For more information, see Using the IAM Policy Simulator (AWS CLI and AWS API) in the AWS IAM User Guide.

Output

ContextKeyNames -> (list)

The list of context keys that are referenced in the input policies.
