get-effective-policies

Description

Gets a list of the policies that have an effect on the authorization behavior of the specified device when it connects to the IoT device gateway.

Requires permission to access the GetEffectivePolicies action.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  get-effective-policies
[--principal <value>]
[--cognito-identity-pool-id <value>]
[--thing-name <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--principal (string)

The principal. Valid principals are CertificateArn (arn:aws:iot:region :accountId :cert/certificateId ), thingGroupArn (arn:aws:iot:region :accountId :thinggroup/groupName ) and CognitoId (region :id ).

--cognito-identity-pool-id (string)

The Cognito identity pool ID.

--thing-name (string)

The thing name.

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

To list the policies that effect a thing

The following get-effective-policies example lists the policies that effect the specified thing, including policies attached to any groups to which it belongs.

aws iot get-effective-policies \
    --thing-name TemperatureSensor-001 \
    --principal arn:aws:iot:us-west-2:123456789012:cert/488b6a7f2acdeb00a77384e63c4e40b18b1b3caaae57b7272ba44c45e3448142
