get-stack-policy

Description

Returns the stack policy for a specified stack. If a stack doesn’t have a policy, a null value is returned.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  get-stack-policy
--stack-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options

--stack-name (string)

The name or unique stack ID that is associated with the stack whose policy you want to get.

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples

To view a stack policy

The following get-stack-policy example displays the stack policy for the specified stack. To attach a policy to a stack, use the set-stack-policy command.

aws cloudformation get-stack-policy \
    --stack-name my-stack

Output:

{
    "StackPolicyBody": "{\n  \"Statement\" : [\n    {\n      \"Effect\" : \"Allow\",\n      \"Action\" : \"Update:*\",\n      \"Principal\": \"*\",\n      \"Resource\" : \"*\"\n    },\n    {\n      \"Effect\" : \"Deny\",\n      \"Action\" : \"Update:*\",\n      \"Principal\": \"*\",\n      \"Resource\" : \"LogicalResourceId/bucket\"\n    }\n  ]\n}\n"
}

Output

StackPolicyBody -> (string)

Structure containing the stack policy body. (For more information, go to Prevent Updates to Stack Resources in the AWS CloudFormation User Guide.)
