ULB.Pool
Element Description
For ECS groups under a shared load balancer, one listener corresponds to multiple ECS groups. You can add or delete ECS groups as required. An ECS group consists of multiple ECSs.
Element Properties
Property |
Mandatory |
Descripiton |
---|---|---|
sessionPersistence |
No |
Session persistence setting Type: ULB.StickySession Value Description: If this option is selected, the session persistence function is enabled by default. Default: {u'type': u'SOURCE_IP'} Suggestion: Set the value based on the live environment. |
protocol |
Yes |
ECS group protocol Type: string Value Description: The options are HTTP and TCP. Value Constraint: The value must be consistent with the listener protocol. Suggestion: Set the value based on the live environment. |
name |
No |
ECS group name Type: string Value Description: Customize the value. Value Constraint: The value supports a maximum of 64 characters and can only contain digits, letters, underscores (_), and hyphens (-). Suggestion: Customize the value. |
lbAlgorithm |
Yes |
Allocation policy type Type: string Value Description: ROUND_ROBIN: indicates the weighted round robin algorithm. LEAST_CONNECTIONS: indicates the weighted least connection. SOURCE_IP: indicates the source IP algorithm. Default: ROUND_ROBIN Value Constraint: The options are ROUND_ROBIN, LEAST_CONNECTIONS, and SOURCE_IP. Suggestion: Set the value based on the live environment. |
listenerId |
Yes |
ID of the belonged listener Type: string Value Description: ID generated after a ULB instance is created, for example, 8abbd7a9-c1f8-440d-96ff-376ee7382082. Value Constraint: The ID must be the listener ID of an existing ULB instance. Suggestion: You are advised to drag the object to the ULB.Listener and use the get_reference function to automatically generate the value. Alternatively, obtain the ULB listener ID on the ULB console and enter it accordingly. |
