Obtaining Metadata of a Stack Set

Function

ShowStackSetMetadata

  • You can use this API to obtain the stack set metadata.

URI

GET /v1/stack-sets/{stack_set_name}/metadata

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

stack_set_name

Yes

String

Stack set name. The name is unique within its domain (domain_id) and region. Only letters, digits, underscores (_), and hyphens (-) are allowed. The name is case-sensitive and must start with a letter.

Minimum: 1

Maximum: 128

Table 2 Query Parameters

Parameter

Mandatory

Type

Description

stack_set_id

No

String

Unique ID of a stack set.

It is a UUID generated by RFS when a stack set is created.

Stack set names are unique only at one specific time, so you can create a stack set named HelloWorld and another stack set with the same name after deleting the first one.

For parallel development in a team, users may want to ensure that the stack set they operate is the one created by themselves, not the one with the same name created by other teammates after deleting the previous one. Therefore, they can use this ID for strong matching.

RFS ensures that the ID of each stack set is different and does not change with updates. If the stack_set_id value is different from the current stack set ID, 400 is returned.

Minimum: 36

Maximum: 36

stack_set_name

String

Name of a stack set. The name is unique within its domain (domain_id) and region. Only letters, digits, underscores (_), and hyphens (-) are allowed. The name is case-sensitive and must start with a letter.

Minimum: 1

Maximum: 128

stack_set_description

String

Description of a stack set. It can be used by customers to identify their own stack sets.

Minimum: 0

Maximum: 1024

initial_stack_description

String

Description of stacks that is being initialized. It can be used to identify stacks managed by a stack set.

This description is used for stacks in the stack set only when they are created. To update the description of stacks that is being initialized, call the UpdateStackSet API.

If the stack set description is updated later, the managed stack description will not be updated synchronously.

Minimum: 0

Maximum: 1024

permission_model

String

Permission model. It defines the creation mode of the agency required for RFS to operate stack sets. The permission model can be: * SERVICE_MANAGED: You can use this model to create stack sets only after setting RFS as a trustworthy service in your organization. You do not need to manually create agencies. RFS automatically creates agencies for you based on the organization. Only an organization administrator or a delegated administrator can create stack sets using SERVICE_MANAGED permissions. * SELF_MANAGED: For deployment, you manually create agencies in advance, including the agency created by the management account for RFS and the agency created by the member account for the management account. The stack set creation will not fail even if the agency does not exist or is incorrect. An error is reported only when the stack set or stack instance is deployed.

Default: SELF_MANAGED

Enumeration values:

  • SELF_MANAGED

administration_agency_name

String

Administration agency names.

RFS uses this agency to obtain permissions that a member account grants to a management account.

This agency must contain the iam:tokens:assume permission to subsequently obtain the managed agency credentials. If it is not included, adding or deploying instances will fail.

When you define SELF_MANAGED permissions, you must specify either administration_agency_name or administration_agency_urn, but not both.

You are advised to specify administration_agency_urn when using a trust agency. administration_agency_name only receives agency names. If trust agency names are assigned to administration_agency_name, template fails to be deployed.

Do not specify this parameter when SERVICE_MANAGED permissions are used. Otherwise, error code 400 is returned.

Minimum: 0

Maximum: 64

managed_agency_name

String

Name of the managed agency.

RFS uses this agency to obtain the permissions required for deploying resources.

The names of the agencies that different member accounts grants to the management account must be the same. Currently, different agency permissions cannot be defined based on different providers.

This parameter must be specified when SELF_MANAGED permissions are defined. Do not specify this parameter when SERVICE_MANAGED permissions are used. Otherwise, error code 400 is returned.

Minimum: 0

Maximum: 64

status

String

The stack set status can be:

  • IDLE: The stack set is idle.
  • OPERATION_IN_PROGRESS: The stack set operation is in progress.
  • DEACTIVATED: The stack set is disabled.

Enumeration values:

  • IDLE
  • OPERATION_IN_PROGRESS
  • DEACTIVATED

vars_uri_content

String

File content corresponding to vars_uri.

vars_body

String

Content of the HCL variable file. Transferring parameters is supported by the HCL template. The same template can use different parameters for different purposes.

  • The vars_body uses the tfvars format of HCL. You can submit the content in the .tfvars file to the vars_body.
  • RFS supports vars_structure, vars_body, and vars_uri. If they declare the same variable, error 400 will be reported.
  • If vars_body is too large, you can use vars_uri.
  • Stack sets do not encrypt sensitive data. RFS uses, logs, displays, and stores vars_body as plaintext.

Minimum: 0

Maximum: 51200

create_time

String

Time when a stack set is created. It uses a UTC (YYYY-MM-DDTHH:mm:ss.SSSZ) format, for example, 1970-01-01T00:00:00.000Z.

update_time

String

Time when a stack set is updated. It uses a UTC (YYYY-MM-DDTHH:mm:ss.SSSZ) format, for example, 1970-01-01T00:00:00.000Z.

administration_agency_urn

String

Administration agency URNs.

RFS uses this agency to obtain permissions that a member account grants to a management account.

This agency must contain the sts:tokens:assume permission to subsequently obtain the managed agency credentials. If it is not included, adding or deploying instances will fail.

When you define SELF_MANAGED permissions, you must specify either administration_agency_name or administration_agency_urn, but not both.

You are advised to specify administration_agency_urn when using a trust agency. administration_agency_name only receives agency names. If trust agency names are assigned to administration_agency_name, template fails to be deployed.

Do not specify this parameter when SERVICE_MANAGED permissions are used. Otherwise, error code 400 is returned.

managed_operation

managed_operation object

A set of properties used to manage the stack set operation.

Table 5 managed_operation

Parameter

Type

Description

enable_parallel_operation

Boolean

This parameter indicates whether the stack set can create multiple stack set operations concurrently. As an attribute of the stack set, this parameter can be specified by using CreateStackSet API and updated by using UpdateStackSet API.

When false (default), the stack set performs one operation at a time in request order. To be specific, at a time, only one stack set operation in QUEUE_IN_PROGRESS or OPERATION_IN_PROGRESS status can be processed.

When true, the stack set can create operations concurrently, handle non-conflicting operations, and queue conflicting operations.

Note: When the stack set allows multiple operations to be created at the same time, if more than one operation deploys same stack instances, these operations are called conflicting operations.

When the stack set is in OPERATION_IN_PROGRESS status, this parameter is not allowed to be modified by UpdateStackSet API.

Currently, a maximum of 10 stack set operations in QUEUE_IN_PROGRESS or OPERATION_IN_PROGRESS status can exist in one stack set.
