UpdateEndpointGroups-阿里云帮助中心

Updates multiple endpoint groups for a listener.

Operation description

Usage

UpdateEndpointGroups is an asynchronous API. After you send a request, the system returns a request ID and performs the update in the background. You can call DescribeEndpointGroup or ListEndpointGroups to query the status of the endpoint group:
- While an endpoint group is in the updating state, you can only perform queries on it.
- When an endpoint group is in the active state, the update is complete.
You cannot use the UpdateEndpointGroups operation to concurrently update endpoint groups that belong to the same Global Accelerator instance.

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.

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The ID of the region where the Global Accelerator instance is deployed. The value must be cn-hangzhou.	cn-hangzhou
ClientToken	string	No	The client token that is used to ensure the idempotency of the request. You can generate the token from your client, but you must make sure that the token is unique among different requests. The `ClientToken` can contain only ASCII characters. Note If you do not specify this parameter, the system automatically uses the RequestId of the request as the ClientToken. The RequestId of each request is different.	123e4567-e89b-12d3-a456-426655440000
DryRun	boolean	No	Specifies whether to perform a dry run. Valid values: true: Performs a dry run to check the request for issues, including required parameters, request format, and business limits. No endpoint groups are modified. If the request fails the dry run, an error message is returned. If the request is valid, a 2xx HTTP status code is returned. false (default): Sends a normal request. If the request is valid, the operation is performed and a 2xx HTTP status code is returned.	true

EndpointConfigurations	array<object>	No	The configurations of the endpoints.
	object	Yes	The configurations of the endpoints.
Type	string	Yes	The type of endpoint. Domain: a custom domain name. Ip: a custom IP address. IpTarget: a custom private IP address. PublicIp: an Alibaba Cloud public IP address. ECS: an Alibaba Cloud ECS instance. SLB: an Alibaba Cloud SLB instance. ALB: an Alibaba Cloud ALB instance. OSS: an Alibaba Cloud OSS instance. ENI: an Alibaba Cloud elastic network interface. NLB: an Alibaba Cloud NLB instance. Note If the endpoint type is ECS, ENI, SLB, ALB, NLB, or IpTarget and the required service-linked role does not exist, the system automatically creates a service-linked role named AliyunServiceRoleForGaVpcEndpoint. If the endpoint type is ALB and the required service-linked role does not exist, the system automatically creates a service-linked role named AliyunServiceRoleForGaAlb. If the endpoint type is OSS and the required service-linked role does not exist, the system automatically creates a service-linked role named AliyunServiceRoleForGaOss. Note For more information, see service-linked roles.	Ip
Weight	integer	Yes	The weight of the endpoint. Valid values: 0 to 255. Note If you set the weight of an endpoint to 0, Global Accelerator stops routing traffic to the endpoint. Use this setting with caution.	20
Endpoint	string	Yes	The IP address, domain name, or instance ID that corresponds to the endpoint type.	47.0.XX.XX
SubAddress	string	No	The private IP address of the elastic network interface (ENI). Note This parameter is optional when the endpoint type is ENI. If you do not specify this parameter, the primary private IP address of the ENI is used.	172.168.XX.XX
EnableClientIPPreservation	boolean	No	Specifies whether to preserve client IP addresses. Valid values: true: preserves client IP addresses. false (default): does not preserve client IP addresses. Note By default, client IP preservation is disabled for endpoint groups for TCP and UDP listeners. You can enable this feature as needed. By default, client IP preservation is enabled for endpoint groups for HTTP and HTTPS listeners. Client IP addresses are retrieved from the X-Forwarded-For header. You cannot disable this feature. `EnableClientIPPreservation` and `EnableProxyProtocol` cannot both be set to `true`. For more information, see Preserve client IP addresses.
EnableProxyProtocol	boolean	No	Specifies whether to use the Proxy Protocol to preserve client IP addresses. Valid values: true: enables this feature. false (default): disables this feature.

	object	No	The port mapping.
ListenerPort	integer	No	The listener port. Valid values: 1 to 65499. Note For TCP listeners, virtual endpoint groups do not support port mappings. If a virtual endpoint group already exists for the listener, you cannot configure port mappings for the default endpoint group. If port mappings are already configured for the default endpoint group, you cannot add a virtual endpoint group. After you configure port mappings, you cannot change the listener protocol, except for switching between HTTP and HTTPS. When you modify the listener port range, the new range must include all listener ports that are specified in the port mappings. For example, if the listener port range is 80-82 and port mappings are configured for this range, you cannot change the listener port range to 80-81.	443
