set-stack-policy¶

Description¶

Sets a stack policy for a specified stack.

Synopsis¶

  set-stack-policy
--stack-name <value>
[--stack-policy-body <value>]
[--stack-policy-url <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--stack-name (string)

The name or unique stack ID that you want to associate a policy with.

--stack-policy-body (string)

Structure containing the stack policy body. For more information, go to Prevent updates to stack resources in the CloudFormation User Guide. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.

--stack-policy-url (string)

Location of a file containing the stack policy. The URL must point to a policy (maximum size: 16 KB) located in an Amazon S3 bucket in the same Amazon Web Services Region as the stack. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.

--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.

See ‘aws help’ for descriptions of global parameters.

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 apply a stack policy

The following set-stack-policy example disables updates for the specified resource in the specified stack. stack-policy.json is a JSON document that defines the operations allowed on resources in the stack.

aws cloudformation set-stack-policy \
    --stack-name my-stack \
    --stack-policy-body file://stack-policy.json

Output:

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