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 continues to run in the background. You can call DescribeEndpointGroup to query the state of an endpoint group:
- If the endpoint group is in the updating state, its configurations are being modified. In this state, you can only perform query operations.
- If the endpoint group is in the active state, its configurations have been modified.
You cannot concurrently call UpdateEndpointGroup to modify the configurations of endpoint groups in 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 region ID of the Global Accelerator instance. Set the value to cn-hangzhou.	cn-hangzhou
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. Generate a parameter value from your client to make sure that the value is unique among different requests. The token 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 may be different for each request.	123e4567-e89b-12d3-a456-426655440000
EndpointGroupId	string	Yes	The ID of the endpoint group.	epg-bp1dmlohjjz4kqaun****

EndpointGroupRegion	string	Yes	The ID of the region where the endpoint group is deployed.	cn-hangzhou
TrafficPercentage	integer	No	The weight of the endpoint group. When a listener is associated with multiple endpoint groups, traffic is distributed to the endpoint groups based on their weights.	20
HealthCheckIntervalSeconds	integer	No	The interval between two consecutive health checks. Unit: seconds. Valid values: 1 to 50.	3

HealthCheckProtocol	string	No	The protocol that is used for health checks. Valid values: tcp or TCP: TCP http or HTTP: HTTP https or HTTPS: HTTPS	HTTPS
ThresholdCount	integer	No	The number of consecutive health check failures that must occur before a healthy endpoint is considered unhealthy, or the number of consecutive health check successes that must occur before an unhealthy endpoint is considered healthy. Valid values: 2 to 10.	3
EndpointConfigurations	array<object>	No	The configurations of the endpoints.
	object	No	The configurations of the endpoints.
Type	string	Yes	The type of the endpoint. Valid values: 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 ENI. NLB: an Alibaba Cloud NLB instance. Note If you set the endpoint type to ECS, ENI, SLB, ALB, NLB, or IpTarget, and the service-linked role AliyunServiceRoleForGaVpcEndpoint does not exist, the system automatically creates the service-linked role. If you set the endpoint type to ALB, and the service-linked role AliyunServiceRoleForGaAlb does not exist, the system automatically creates the service-linked role. If you set the endpoint type to OSS, and the service-linked role AliyunServiceRoleForGaOss does not exist, the system automatically creates the service-linked role. If you set the endpoint type to NLB, and the service-linked role AliyunServiceRoleForGaNlb does not exist, the system automatically creates the service-linked role. Note For more information, see Service-linked roles.	Ip
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 address preservation is disabled for endpoint groups of UDP and TCP listeners. You can enable it as needed. By default, client IP address preservation is enabled for endpoint groups of HTTP and HTTPS listeners. The client IP addresses are obtained from the X-Forwarded-For header. You cannot disable this feature. EnableClientIPPreservation and EnableProxyProtocol cannot be both set to true. For more information, see Preserve client IP addresses.	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, Global Accelerator stops distributing traffic to the endpoint. Handle this with care.	20
EnableProxyProtocol	boolean	No	Specifies whether to use the proxy protocol to preserve client IP addresses. Valid values: true: uses the proxy protocol. false (default): does not use the proxy protocol. Note This parameter is available only for endpoint groups of TCP listeners. EnableClientIPPreservation and EnableProxyProtocol cannot be both set to true. For more information, see Preserve client IP addresses.	false
Endpoint	string	Yes	The IP address, domain name, or instance ID of the endpoint, based on the value of Type.	120.XX.XX.21
SubAddress	string	No	The private IP address of the ENI. Note This parameter is available only 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
VpcId	string	No	The ID of the VPC. You can specify up to one VPC ID for an endpoint group that is associated with a listener that uses smart routing. Note This parameter is required and takes effect only when the endpoint type is IpTarget.	vpc-2zen6t0u7xhm0k5iz****

PortOverrides	array<object>	No	The port mapping.
	object	No	The port mapping.
ListenerPort	integer	No	The listener port that is mapped to the endpoint port. Note For TCP listeners, virtual endpoint groups do not support port mapping. If a listener is already associated with a virtual endpoint group, you cannot configure port mapping for the default endpoint group. If you have configured port mapping for the default endpoint group, you cannot add a virtual endpoint group to the listener. After you configure port mapping, the following limits apply when you modify the listener: You cannot change the listener protocol, except for switching between HTTP and HTTPS. Listener port: The modified listener port range must include all listener ports that are configured in the existing port mappings. For example, if the current listener port range is 80-82 and you have mapped listener ports 80, 81, and 82 to endpoint ports 100, 101, and 102, you cannot change the listener port range to 80-81.	443
