Class NodegroupScalingConfig

java.lang.Object
software.amazon.awssdk.services.eks.model.NodegroupScalingConfig
All Implemented Interfaces:
Serializable, SdkPojo, ToCopyableBuilder<NodegroupScalingConfig.Builder,NodegroupScalingConfig>
@Generated("software.amazon.awssdk:codegen") public final class NodegroupScalingConfig extends Object implements SdkPojo, Serializable, ToCopyableBuilder<NodegroupScalingConfig.Builder,NodegroupScalingConfig>

An object representing the scaling configuration details for the Auto Scaling group that is associated with your node group. When creating a node group, you must specify all or none of the properties. When updating a node group, you can specify any or none of the properties.

  • Method Details

    • minSize

      public final Integer minSize()

      The minimum number of nodes that the managed node group can scale in to.

      Returns:
      The minimum number of nodes that the managed node group can scale in to.

    • maxSize

      public final Integer maxSize()

      The maximum number of nodes that the managed node group can scale out to. For information about the maximum number that you can specify, see Amazon EKS service quotas in the Amazon EKS User Guide.

      Returns:
      The maximum number of nodes that the managed node group can scale out to. For information about the maximum number that you can specify, see Amazon EKS service quotas in the Amazon EKS User Guide.

    • desiredSize

      public final Integer desiredSize()

      The current number of nodes that the managed node group should maintain.

      If you use the Kubernetes Cluster Autoscaler, you shouldn't change the desiredSize value directly, as this can cause the Cluster Autoscaler to suddenly scale up or scale down.

      Whenever this parameter changes, the number of worker nodes in the node group is updated to the specified size. If this parameter is given a value that is smaller than the current number of running worker nodes, the necessary number of worker nodes are terminated to match the given value. When using CloudFormation, no action occurs if you remove this parameter from your CFN template.

      This parameter can be different from minSize in some cases, such as when starting with extra hosts for testing. This parameter can also be different when you want to start with an estimated number of needed hosts, but let the Cluster Autoscaler reduce the number if there are too many. When the Cluster Autoscaler is used, the desiredSize parameter is altered by the Cluster Autoscaler (but can be out-of-date for short periods of time). the Cluster Autoscaler doesn't scale a managed node group lower than minSize or higher than maxSize.

      Returns:
      The current number of nodes that the managed node group should maintain.

    • toBuilder

      public NodegroupScalingConfig.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<NodegroupScalingConfig.Builder,NodegroupScalingConfig>
      Returns:
      a builder for type T

    • builder

      public static NodegroupScalingConfig.Builder builder()

    • serializableBuilderClass

      public static Class<? extends NodegroupScalingConfig.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
