/AWS1/CL_EKSWARMPOOLCONFIG

The configuration for an Amazon EC2 Auto Scaling warm pool attached to an Amazon EKS managed node group. Warm pools maintain pre-initialized EC2 instances alongside your Auto Scaling group that have already completed the bootup initialization process and can be kept in a Stopped, Running, or Hibernated state.

CONSTRUCTOR

IMPORTING

Optional arguments:

iv_enabled TYPE /AWS1/EKSBOXEDBOOLEAN /AWS1/EKSBOXEDBOOLEAN

Specifies whether to attach warm pools on the managed node group. Set to true to enable the warm pool, or false to disable and remove it. If not specified during an update, the current value is preserved.

iv_minsize TYPE /AWS1/EKSZEROCAPACITY /AWS1/EKSZEROCAPACITY

The minimum number of instances to maintain in the warm pool. Default: 0. Size your warm pool based on scaling patterns to balance cost and availability. Start with 10-20% of expected peak capacity.

iv_maxgrouppreparedcapacity TYPE /AWS1/EKSBOXEDINTEGER /AWS1/EKSBOXEDINTEGER

The maximum total number of instances across the warm pool and Auto Scaling group combined. This value controls the total prepared capacity available for your node group.

iv_poolstate TYPE /AWS1/EKSWARMPOOLSTATE /AWS1/EKSWARMPOOLSTATE

The desired state for warm pool instances. Default: Stopped. Valid values are Stopped (most cost-effective with EBS storage costs only), Running (fastest transition time with full EC2 costs), and Hibernated (balance between cost and speed, only supported on specific instance types). Warm pool instances in the Hibernated state are not supported with Bottlerocket AMIs.

iv_reuseonscalein TYPE /AWS1/EKSBOXEDBOOLEAN /AWS1/EKSBOXEDBOOLEAN

Indicates whether instances should return to the warm pool during scale-in events instead of being terminated. Default: false. Enable this to reduce costs by reusing instances. This feature is not supported for Bottlerocket AMIs.
