Instance Method Details

#wait(params = {}) ⇒ `Types::DescribeStacksOutput`

Returns a response object which responds to the following methods:

#stacks => Array<Types::Stack>
#next_token => String

Options Hash (params):

:stack_name (String) —
<note markdown=“1”> If you don’t pass a parameter to ‘StackName`, the API returns a response that describes all resources in the account, which can impact performance. This requires `ListStacks` and `DescribeStacks` permissions.
```
Consider using the ListStacks API if you're not passing a parameter
```
to ‘StackName`.
```
The IAM policy below can be added to IAM policies when you want to
```
limit resource-level permissions and avoid returning a response when no parameter is sent in the request:
```
\\\{ "Version": "2012-10-17", "Statement": \[\\\{ "Effect":
```
“Deny”, “Action”: “cloudformation:DescribeStacks”, “NotResource”: “arn:aws:cloudformation:::stack//” \}] \}
```
</note>
```
The name or the unique stack ID that’s associated with the stack, which aren’t always interchangeable:
- Running stacks: You can specify either the stack’s name or its unique stack ID.
- Deleted stacks: You must specify the unique stack ID.
Default: There is no default value.
:next_token (String) —

A string that identifies the next page of stacks that you want to retrieve.

Returns:

(Types::DescribeStacksOutput) —
Returns a response object which responds to the following methods:
- #stacks => Array<Types::Stack>
- #next_token => String
