CCE.Addon.AutoScaler

Element Description

CCE.Addon.AutoScaler is a plug-in for node auto-scaling in a K8S cluster.

Element Properties

**Table 1** Property Description
Property	Required	Descripiton
scaleDownUtilizationThreshold	No	Node resource usage ratio Type: float Value Description: Supports the range of 0 to 1. Default: 0.4 Value Constraint: The value ranges from 0 to 1. Suggestion: Select a port in the range as required.
clusterId	Yes	ID of the cluster to which the resource belongs Type: HuaweiCloud.CCE.Cluster.Id Value Description: Indicates the ID of an existing or new container cluster. Value Constraint: The value must satisfy the UUID rule and support a maximum of 64 characters. Suggestion: Enter the cluster ID. Specifically, log in to the CCE console, and choose Resource Management > Clusters. Click the target cluster, and you can then obtain its cluster ID. Connect to the cluster object and use the get_reference function to obtain the cluster ID.
scaleDownEnabled	Yes	scale down function switch Type: boolean Default: False
publicKey	No	public key Type: HuaweiCloud.ECS.KeyPair.PublicKey
nodePasswd	No	node root user password Type: password
nodes	Yes	autoscaler nodes with AZ, flavor, and OS ,taints Type: CCE.Addon.AutoScaler.Node Array Suggestion: During scaling, taints are arrays, including key, value, and effect. The effect can be set to NoSchedule, PreferNoSchedule, or NoExecute.
sshKeyName	No	name of sshKey Type: HuaweiCloud.ECS.KeyPair.Name
scaleDownUnneededTime	No	When a node remains idle for this specified time duration (in minutes), scaling in will be performed. Type: integer Value Description: Supports the range of 1 to 1000. Default: 10 Value Constraint: The value ranges from 1 to 1000. Suggestion: Select a port in the range as required.
