UpdateEndpointGroup - Global Accelerator - Alibaba Cloud Documentation Center

Modifies the configurations of an endpoint group.

Operation description

UpdateEndpointGroup is an asynchronous operation. After you send a request, the system returns a request ID, but the operation is still being performed in the system background. You can call the DescribeEndpointGroup operation to query the state of an endpoint group.
- If the endpoint group is in the updating state, it indicates that the configurations of the endpoint group are being modified. In this case, you can perform only query operations.
- If the endpoint group is in the active state, it indicates that the configurations of the endpoint group are modified.
The UpdateEndpointGroup operation cannot be repeatedly called for the same Global Accelerator (GA) instance within a specific period of time.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Operation	Access level	Resource type	Condition key	Associated operation

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The ID of the region where the GA instance is deployed. Set the value to cn-hangzhou.	cn-hangzhou
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the token, but you must make sure that the token is unique among different requests. The client token can contain only ASCII characters. Note If you do not specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.	123e4567-e89b-12d3-a456-426655440000
EndpointGroupId	string	Yes	The ID of the endpoint group.	epg-bp1dmlohjjz4kqaun****

Description	string	No	The description of the endpoint group. The description can be up to 200 characters in length and cannot start with `http://` or `https://`.	EndpointGroup
EndpointGroupRegion	string	Yes	The ID of the region where the endpoint group is created.	cn-hangzhou
TrafficPercentage	integer	No	The weight of the endpoint group when the listener is associated with multiple endpoint groups.	20
HealthCheckIntervalSeconds	integer	No	The interval between two consecutive health checks. Unit: seconds. Valid values: 1 to 50.	3
HealthCheckPath	string	No	The path to which health check requests are sent.	/healthcheck
HealthCheckPort	integer	No	The port that is used for health checks. Valid values: 1 to 65535.	20
HealthCheckProtocol	string	No	The protocol over which to send health check requests. Valid values: tcp or TCP http or HTTP https or HTTPS	tcp
ThresholdCount	integer	No	The number of consecutive health check failures that must occur before a healthy endpoint group is considered unhealthy, or the number of consecutive health check successes that must occur before an unhealthy endpoint group is considered healthy. Valid values: 2 to 10.	3
EndpointConfigurations	array<object>	No	The configurations of endpoints in the endpoint group.
	object	No	The configurations of endpoints in the endpoint group.
Type	string	Yes	The type of the endpoint. Valid values: Domain: a custom domain name. Ip: a custom IP address. PublicIp: a public IP address provided by Alibaba Cloud. ECS: an Elastic Compute Service (ECS) instance. SLB: a Classic Load Balancer (SLB) instance. ALB: an Application Load Balancer (ALB) instance. OSS: an Object Storage Service (OSS) bucket. ENI: an elastic network interface (ENI). NLB: a Network Load Balancer (NLB) instance. Note If you set this parameter to ECS, ENI, SLB, ALB, or NLB and the AliyunServiceRoleForGaVpcEndpoint service-linked role does not exist, the system automatically creates the service-linked role. If you set this parameter to ALB and the AliyunServiceRoleForGaAlb service-linked role does not exist, the system automatically creates the role. If you set this parameter to OSS and the AliyunServiceRoleForGaOss service-linked role does not exist, the system automatically creates the role. If you set this parameter to NLB and the AliyunServiceRoleForGaNlb service-linked role does not exist, the system automatically creates the role. For more information, see Service-linked roles.	Ip
EnableClientIPPreservation	boolean	No	Specifies whether to preserve client IP addresses by using the TCP Option Address (TOA) module. Valid values: true false (default)	false
Weight	integer	Yes	The weight of the endpoint. Valid values: 0 to 255. Note If you set the weight of an endpoint to 0, GA stops distributing traffic to the endpoint. Proceed with caution.	20
EnableProxyProtocol	boolean	No	Specifies whether to use the proxy protocol to preserve client IP addresses. Valid values: true false (default)	false
Endpoint	string	Yes	Enter the IP address, domain name, or instance ID based on the value of the Type parameter.	120.XX.XX.21
SubAddress	string	No	The private IP address of the ENI. Note This parameter is available only when you set the endpoint type to ENI. If you leave this parameter empty, the primary private IP address of the ENI is used.	172.168.XX.XX

Valid values: HTTP HTTPS Note You can set this parameter only when the listener that is associated with the endpoint group uses the HTTP or HTTPS protocol. For an HTTP listener, the backend service protocol must be HTTP.	HTTP
