Creating a Trust Agency

Function

This API is used to create a trust agency.

Trust agencies can only have identity policies attached and are only compatible with cloud services that support identity policies. For details, see Cloud Services for Using Identity Policies and Trust Agencies.

Authorization Information

Each account root user has all the permissions required to call all APIs, but IAM users must be assigned the following required identity policy-based permissions. For details about the required permissions, see Permissions Policies and Supported Actions.

Request Parameters

Table 1 Request body parameters

Parameter

Mandatory

Type

Description

agency_name

Yes

String

Definition

Name of a trust agency.

Constraints

N/A

Range

The value contains 1 to 64 characters. Only letters, digits, underscores (_), plus signs (+), equal signs (=), commas (,), periods (.), at signs (@), and hyphens (-) are allowed.

Default Value

N/A

path

No

String

Definition

Resource path. A resource path is a hierarchical path used to organize and classify resources, which is similar to the directory structure in a file system.

Constraints

N/A

Range

The value consists of one or more concatenated string segments, with a total length of 0 to 512 characters. Each segment contains one or more letters, digits, periods (.), commas (,), plus signs (+), at signs (@), equal signs (=), underscores (_), or hyphens (-), and ends with a slash (/), for example, foo/bar/.

Default Value

The value is an empty string by default.

trust_policy

Yes

String

Definition

JSON format of the policy document of a trust agency's trust policy.

Constraints

Characters =, <, >, (, ), and | are special characters in the grammar and are not included in trust policies.

The question mark (?) indicates an element is optional, for example, sid_block?.

The vertical bar (|) indicates options, and the parenthesis define the range of options, for example, ("Allow" | "Deny").

When an element allows multiple values, use duplicate values, (,), and (...), for example, [ <policy_statement>, <policy_statement>, ... ].

The following recursive grammar describes the syntax of trust policies:

policy = {
  <version_block>,
  <statement_block>
}

<version_block> = "Version" : ("5.0")

<statement_block> = "Statement" : [ <policy_statement>, <policy_statement>, ... ]

<policy_statement> = {
  <sid_block?>,
  <principal_block>,
  <effect_block>,
  <action_block>,
  <resource_block?>,
  <condition_block?>
}

<sid_block> = "Sid" : <sid_string>

<principal_block> = ("Principal" | "NotPrincipal") : <principal_map>

<principal_map> = { <principal_map_entry>, <principal_map_entry>, ... }

<principal_map_entry> = ("IAM" | "Service" | "Identity_provider") : [ <principal_id_string>, ... | <service_principal_string>, ... | <identity_provider_principal_string>, ... ]

<effect_block> = "Effect" : ("Allow" | "Deny")

<action_block> = ("Action" | "NotAction") : [ <action_string>, <action_string>, ... ]

<resource_block> = ("Resource" | "NotResource") : [ <resource_string>, <resource_string>, ... ]

<condition_block> = "Condition" : { <condition_map> }

<condition_map> = {
  <condition_type_string> : { <condition_key_string> : <condition_value_list> },
  <condition_type_string> : { <condition_key_string> : <condition_value_list> },
  ...
}

<condition_value_list> = ( <condition_value> | [ <condition_value>, <condition_value>, ... ] )

<condition_value> = "string"
