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.

Request parameters

Parameter	Type	Required	Description	Example
AppId	string	Yes	The ID of the application. You can query the application ID by calling the ListApplication operation. For more information, see ListApplication .	5a166fbd-**-**-a286-781659d9f54c
ClusterId	string	Yes	The ID of the cluster. You can query the cluster ID by calling the GetK8sCluster operation. For more information, see GetK8sCluster .	712082c3-**-**-9217-a947b5cde6ee
Type	string	Yes	The type of the SLB instance. Valid values: Internet: an Internet-facing SLB instance Intranet: an internal-facing SLB instance	Internet
SlbProtocol	string	No	The protocol used by the SLB instance. Set the value to TCP.	TCP
TargetPort	string	No	The backend port, which is also the service port of the application. Valid values: 1 to 65535.	8082
Port	string	No	The frontend port. Valid values: 1 to 65535.	80
ServicePortInfos	string	No	The information about the ports. This parameter is required if you want to configure multi-port mappings or use a protocol other than TCP. You must set this parameter to a JSON array. Example: [{"targetPort":8080,"port":82,"loadBalancerProtocol":"TCP"},{"port":81,"certId":"1362469756373809_16c185d6fa2_1914500329_-xxxxxxx","targetPort":8181,"lo adBalancerProtocol":"HTTPS"}] port: required. The frontend port. Valid values: 1 to 65535. Each port must be unique. targetPort: required. The backend port. Valid values: 1 to 65535. loadBalancerProtocol: required. Valid values: TCP and HTTPS. If the HTTP protocol is used, set this parameter to TCP. certId: the ID of the certificate. This parameter is required if the HTTPS protocol is used. You can purchase an SLB instance in the SLB console. Note: The ServicePortInfos parameter is specified to support multi-port mappings. If you want this parameter to take effect, make sure that you specify the AppId, ClusterId, Type, and SlbId parameters.	{"targetPort":8080,"port":82,"loadBalancerProtocol":"TCP"},{"port":81,"certId":"136246975637380916c185d6fa21914500329_-xxxxxxx","targetPort":8181,"lo adBalancerProtocol":"HTTPS"}
Specification	string	No	The specifications of the SLB instance. slb.s1.small slb.s2.small slb.s2.medium slb.s3.small slb.s3.medium slb.s3.large If you do not specify this parameter, the default value slb.s1.small is used.	slb.s1.small
Scheduler	string	No	The scheduling algorithm for the SLB instance. If you do not specify this parameter, the default value rr is used. SLB supports the following scheduling algorithms: round-robin and weighted round-robin. Valid values: wrr: weighted round-robin scheduling. Backend servers that have higher weights receive more requests than those that have lower weights. rr: round-robin scheduling. Requests are sequentially distributed to backend servers.	wrr
SlbName	string	No	The name of the SLB instance.	SLB_doctest
DisableForceOverride	boolean	No	Specifies whether to disable listener configuration overriding. true: disables listener configuration overriding. false: enables listener configuration overriding.	true
