Creating a Stack

Function

This API is used to create a stack.

The stack input consists of the template and input parameters.

Template defines the framework of the stack, and determines the structure of the internal nodes of the stack, the relationships between nodes, and the value or source of the attributes of each node.
Input parameters are one of the sources of the node attribute values in the template. They are defined in the input fields of the template and are triggered by the get_input function in the template.

Request Parameters

**Table 1** Request Parameters
Parameter	Mandatory	Data Type	Description
name	Yes	String	Stack name Restrictions are the same as the name field in Table 2.
project_id	Yes	String	ID of the project to which the stack belongs. The default value is the project to which the user token belongs. If this parameter is set, the value must be the same as the project information in the user token. The value supports a maximum of 63 characters and cannot start or end with a hyphen (-). Only lowercase letters, digits, and hyphens are allowed.
description	No	String	Stack description Restrictions are the same as the description field in Table 2.
template_id	Yes	String	ID of the template used by the stack. The value supports a maximum of 64 characters.
inputs_json	No	Object	Input parameter of the template used by the stack. Each key-value structure in this parameter corresponds to a key field in the inputs, and the input value is value. If a key is not specified, the default value specified by the key is used. If no default value is specified, an error is reported. Example: "{'template_input_key': 'value'}"
force	No	Boolean	Force tailoring ID of the stack. This parameter is applicable to tailoring scenarios.
labels	No	Object	Stack label. Each internal key-value indicates a label. The key/value field supports a maximum of 64 characters, and must comply with the regular expression ^[a-zA-Z0-9_]+[-.a-zA-Z0-9_]*$.
namespace	No	String	This parameter must be specified when CCE resources and applications are orchestrated. If the value is not read from CCE, default is used by default.
cluster_id	No	String	This parameter must be specified when CCE resources and applications are orchestrated. ID of the cluster to which the stack belongs.
action_parameters	No	Object	After a stack is created, lifecycle configurations are automatically executed and installed. Restrictions are the same as those in Table 2.

**Table 2** Lifecycle configurations
Parameter	Mandatory	Data Type	Description
failure_strategy	No	String	Failure strategy. The default value is DoNothing. The value can be DoNothing or Rollback.
auto_create	Yes	Boolean	The default value is true.
timeout	No	Integer	Lifecycle timeout period (in minutes). The default value is 60 minutes. The value supports a maximum of 1,440 minutes (that is, one day).

When the inputs_json parameter is set to the attribute of a VM application and a valid URL is not entered in the url or name field, the name/version/repository field is used to access SWR for fuzzy search. The efficiency is low when there are a large number of files in the software repository. A feasible solution is to fill in the url field to avoid fuzzy search or specify the name, version, repository parameters in detail to reduce the search scope.

url: http://SWR.url/xxx/file.tgz (recommended)
name: file.tgz; version: v1; repository: myProject (good)
name: file.tgz (low-efficiency)

Response message.

Response Parameters

A response parameter is a stack structure or response structure.

The stack structure is returned when the creation is successful.
The error response structure is returned when the creation fails.

The stack structure is shown in Table 3 Response parameters and the returned incorrect response structure is shown in Table 5.
