CreateErAttachment-阿里云帮助中心

Operation description

When you call this operation to create a network instance connection, note that:

Make sure that you have created a Lingjun HUB instance.
Make sure that you have sufficient quota for network instance connections.
This operation is an asynchronous operation. After you call this operation, the system returns the ID of the network instance connection. In this case, the network instance connection may not be created yet, and the system is still creating the network instance in the background. You can query the connection status of a network instance by ListErAttachments or GetErAttachment:
- If the connection status of the network instance is Executing, the network instance is being created.
- If the connection status of the network instance is Available, the network instance is created.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
