Function

ListStackOutputs

This API lists all outputs of a stack.

The stack output is the return information generated after the deployment of the output statement block defined in the template is complete. After the deployment is complete, you can call this API to obtain the specific output information.

If the stack is in a non-final state (ending with IN_PROGRESS), this API returns empty value. The non-final states may include:

DEPLOYMENT_IN_PROGRESS
DELETION_IN_PROGRESS
ROLLBACK_IN_PROGRESS

Output is defined in the HCL syntax. The returned information is similar to the return value programmatically. For details, refer to the HCL documentation.

Support pagination. If there is next_marker in the response, more output is available than is included in the current response. Use this value in the marker request parameter in a subsequent call to get the next part of the outputs. You should repeat this until the next_marker response is set to null.

URI

GET /v1/{project_id}/stacks/{stack_name}/outputs

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	A project ID is obtained by calling an API or from the console. Obtaining a Project ID
stack_name	Yes	String	A stack name is unique within its domain (domain_id), region, and project (project_id). It is case-sensitive and starts with a letter. Only letters, digits, underscores (_), and hyphens (-) are allowed.

**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
stack_id	No	String	Unique stack ID. It is a UUID generated by RFS when a stack is created. Stack names are unique at one specific time, so you can create a stack named HelloWorld and another stack with the same name after deleting the first one. For parallel development, team members may want to ensure that they are operating the stack they created, not one with the same name created by other members after deleting the previous one. To avoid this mismatch, check the ID, since RFS ensures each stack has a unique ID that does not change with updates. If the stack_id value differs from the current stack ID, 400 is returned.
marker	No	String	Pagination marker. When a single page cannot return all results, the previous request will return a next_marker to indicate there are more pages. Users can place the value of next_marker here to query information from the next page. This marker can only be used for requests with the same parameters as the previous request. If not specified, the query will start from the first page by default.
limit	No	Integer	The maximum number of results to return per page

Request Parameters

**Table 3** Request header parameters
Parameter	Mandatory	Type	Description
Client-Request-Id	Yes	String	A unique request ID is specified by a user to locate a request. UUID is recommended.

Response Parameters

Status code: 200

**Table 4** Response body parameters
Parameter	Type	Description
outputs	Array of StackOutput objects	Stack output list.
page_info	page_info object	Pagination information

**Table 5** StackOutput
Parameter	Type	Description
name	String	Name of a stack output, defined in a template. For example, in the following HCL template, the value of name is vpc_id. output "vpc_id" { value = huaweicloud_vpc.my_hello_world_vpc.id } In a JSON template, the value of name is vpc_id. { "output": { "vpc_id": [ { "value": "${huaweicloud_vpc.my_hello_world_vpc.id}" } ] } }
description	String	Description of a stack output, defined in a template.
type	String	Output type of a stack.
value	String	Output value of a stack.
sensitive	Boolean	Whether a stack output is sensitive. This is defined in a template. If an output is defined as sensitive in a template, the actual value and type of the output will not be returned in the response body. Instead, [/topic/body/section/table/tgroup/tbody/row/entry/p/br {""}) (br] will be returned.

**Table 6** page_info
Parameter	Type	Description
next_marker	String	Forward pagination identifier. Marker for the next set of results. If present, more output is available than is included in the current response. Use this value in the marker request parameter in a subsequent call to get the next part of the outputs. You should repeat this until the next_marker response is set to null.
previous_marker	String	Backward pagination identifier.
current_count	Integer	The number of items returned on current page.

Status code: 400
