2016/02/25 - AWS CloudFormation - 2 updated api methods
{'RetainResources': ['string']}
Deletes a specified stack. Once the call completes successfully, stack deletion starts. Deleted stacks do not show up in the DescribeStacks API if the deletion has been completed successfully.
Request Syntax
client.delete_stack(
StackName='string',
RetainResources=[
'string',
]
)
string
[REQUIRED]
The name or the unique stack ID that is associated with the stack.
list
For stacks in the DELETE_FAILED state, a list of resource logical IDs that are associated with the resources you want to retain. During deletion, AWS CloudFormation deletes the stack but does not delete the retained resources.
Retaining resources is useful when you cannot delete a resource, such as a non-empty S3 bucket, but you want to delete the stack.
(string) --
None
{'Tags': [{'Key': 'string', 'Value': 'string'}]}
Updates a stack as specified in the template. After the call completes successfully, the stack update starts. You can check the status of the stack via the DescribeStacks action.
To get a copy of the template for an existing stack, you can use the GetTemplate action.
For more information about creating an update template, updating a stack, and monitoring the progress of the update, see Updating a Stack .

string
[REQUIRED]
The name or unique stack ID of the stack to update.
string
Structure containing the template body with a minimum length of 1 byte and a maximum length of 51,200 bytes. (For more information, go to Template Anatomy in the AWS CloudFormation User Guide.)
Conditional: You must specify either the TemplateBody or the TemplateURL parameter, but not both.
string
Location of file containing the template body. The URL must point to a template that is located in an Amazon S3 bucket. For more information, go to Template Anatomy in the AWS CloudFormation User Guide.
Conditional: You must specify either the TemplateBody or the TemplateURL parameter, but not both.
boolean
Reuse the existing template that is associated with the stack that you are updating.
string
Structure containing the temporary overriding stack policy body. You can specify either the StackPolicyDuringUpdateBody or the StackPolicyDuringUpdateURL parameter, but not both.
If you want to update protected resources, specify a temporary overriding stack policy during this update. If you do not specify a stack policy, the current policy that is associated with the stack will be used.
string
Location of a file containing the temporary overriding stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same region as the stack. You can specify either the StackPolicyDuringUpdateBody or the StackPolicyDuringUpdateURL parameter, but not both.
If you want to update protected resources, specify a temporary overriding stack policy during this update. If you do not specify a stack policy, the current policy that is associated with the stack will be used.
list
A list of Parameter structures that specify input parameters for the stack. For more information, see the Parameter data type.
(dict) --
The Parameter data type.
ParameterKey (string) --
The key associated with the parameter. If you don't specify a key and value for a particular parameter, AWS CloudFormation uses the default value that is specified in your template.
ParameterValue (string) --
The value associated with the parameter.
UsePreviousValue (boolean) --
During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.
list
A list of capabilities that you must specify before AWS CloudFormation can create or update certain stacks. Some stack templates might include resources that can affect permissions in your AWS account. For those stacks, you must explicitly acknowledge their capabilities by specifying this parameter. Currently, the only valid value is CAPABILITY_IAM , which is required for the following resources: AWS::IAM::AccessKey , AWS::IAM::Group , AWS::IAM::InstanceProfile , AWS::IAM::Policy , AWS::IAM::Role , AWS::IAM::User , and AWS::IAM::UserToGroupAddition . If your stack template contains these resources, we recommend that you review any permissions associated with them. If you don't specify this parameter, this action returns an InsufficientCapabilities error.
(string) --
list
The template resource types that you have permissions to work with for this update stack action, such as AWS::EC2::Instance , AWS::EC2::* , or Custom::MyCustomInstance .
If the list of resource types doesn't include a resource that you're updating, the stack update fails. By default, AWS CloudFormation grants permissions to all resource types. AWS Identity and Access Management (IAM) uses this parameter for AWS CloudFormation-specific condition keys in IAM policies. For more information, see Controlling Access with AWS Identity and Access Management .
(string) --
string
Structure containing a new stack policy body. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.
You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you do not specify a stack policy, the current policy that is associated with the stack is unchanged.
string
Location of a file containing the updated stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same region as the stack. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.
You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you do not specify a stack policy, the current policy that is associated with the stack is unchanged.
list
Amazon Simple Notification Service topic Amazon Resource Names (ARNs) that AWS CloudFormation associates with the stack. Specify an empty list to remove all notification topics.
(string) --
list
Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to supported resources in the stack. You can specify a maximum number of 10 tags.
If you don't specify this parameter, AWS CloudFormation doesn't modify the stack's tags. If you specify an empty value, AWS CloudFormation removes all associated tags.
(dict) --
The Tag type is used by CreateStack in the Tags parameter. It allows you to specify a key-value pair that can be used to store information related to cost allocation for an AWS CloudFormation stack.
Key (string) --
Required . A string used to identify this tag. You can specify a maximum of 128 characters for a tag key. Tags owned by Amazon Web Services (AWS) have the reserved prefix: aws: .
Value (string) --
Required . A string containing the value for this tag. You can specify a maximum of 256 characters for a tag value.

Response Structure
(dict) --
The output for a UpdateStack action.
StackId (string) --
Unique identifier of the stack.
