LoadBalancerJoinSecurityGroup - Server Load Balancer - Alibaba Cloud Documentation Center

Adds an Application Load Balancer (ALB) instance to a security group.

Operation description

By default, security groups are unavailable. To use security groups, contact your account manager.
Make sure that a security group is created. For more information about how to create security groups, see CreateSecurityGroup .
Each ALB instance can be added to at most four security groups.
To query the security groups of an ALB instance, call the GetLoadBalancerAttribute operation.
GetLoadBalancerAttribute is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the ListAsynJobs operation to query the status of the task.
- If the task is in the Succeeded state, the ALB instance is added to the security group.
- If the task is in the Processing state, the ALB instance is being added to the security group. In this case, you can query the task but cannot perform other operations.

There is currently no authorization information disclosed in the API.

Parameter	Type	Required	Description	Example
SecurityGroupIds	array	Yes	The security group IDs.
	string	Yes	The security group ID.	sg-m5e7xkprgt1pi1ik****
LoadBalancerId	string	Yes	The ALB instance ID.	alb-h7kcw4g4nnvtqp****
DryRun	boolean	No	Specifies whether to perform only a dry run, without performing the actual request. Valid values: true: performs only a dry run. The system checks the request for potential issues, including missing parameter values, incorrect request syntax, and service limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the `DryRunOperation` error code is returned. false (default): performs a dry run and performs the actual request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed.	false
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 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
