海外TECH	DEV Community	AWS EKS With Amazon EC2 Spot Instances	https://dev.to/awscommunity-asean/aws-eks-with-amazon-ec2-spot-instances-405o	AWS EKS With Amazon EC Spot Instances AbstractThis post provides an overview of Amazon EC Spot Instances as well as best practices for using them on AWS EKS effectively Table Of ContentsWhat to know about spot instances The life cycle of a Spot InstanceHow to Launch Spot InstancesSpot Instance Termination NoticeDeploy the node termination handlerSpot Instance Best PracticesSolutionConclusion What to know about spot instances The life cycle of a Spot Instance You or an application running on your behalf submits a bid to run a desired number of EC instances of a particular type The bid includes the price that you are willing to pay to use the instance for an hour When your bid price exceeds the current Spot price which varies based on supply and demand your instances are run Spot instance is interrupted or reclaimed for one of following reasons Price The Spot price is greater than your maximum price Capacity If there are not enough unused EC instances to meet the demand for On Demand Instances Amazon EC interrupts Spot Instances The order in which the instances are interrupted is determined by Amazon EC Constraints If your request includes a constraint such as a launch group or an Availability Zone group these Spot Instances are terminated as a group when the constraint can no longer be met How to Launch Spot Instances The most recommended service for launching Spot Instances is Amazon EC Auto Scaling especially Amazon EKS node groupIf you require more flexibility have built your own instance launch workflows or want to control individual aspects of the instance launches or the scaling mechanisms you can use EC Fleet in Instant mode Spot Instance Termination Notice The best way for you to gracefully handle Spot Instance interruptions is to architect your application to be fault tolerant To accomplish this you can take advantage of Spot Instance interruption notices A Spot Instance interruption notice is a warning that is issued two minutes before Amazon EC stops or terminates your Spot Instance It s recommended to check for these interruption notices every seconds eg Polling every second s Deploy the node termination handler We will deploy a pod on each Spot Instance to detect the instance termination notification signal so that we can both terminate gracefully any pod that was running on that node drain from load balancers and redeploy applications elsewhere in the cluster The Helm chart we will use to deploy AWS Node Termination Handler on each Spot Instance uses a DaemonSet This will monitor the EC meta data service on each of the EC Spot Instances to capture EC interruption notices Within the Node Termination Handler DaemonSet the workflow can be summarized as Identify that a Spot Instance is being reclaimed Use the minute notification window to gracefully prepare the node for termination Taint the node and cordon it off to prevent new pods from being placed Drain connections on the running pods Replace the pods on remaining nodes to maintain the desired capacity In this post I would like to enable SpotInterruptionDraining on SPOT instances only Read more AWS Node Termination HandlerUsing helm deploy aws node termination handler with enable enableSpotInterruptionDraining and enableRebalanceMonitoring plus webhookURL to send notification to slack apply for spot instances only We use set nodeSelector lifecycle spot to tell the all daemon sets where to place the node termination handler pods but the autoscaling group need to add the label lifecycle spot to it nodes or you can use any labels that matche the requirementhelm repo add eks helm upgrade install aws node termination handler namespace kube system set enableSpotInterruptionDraining true set enableRebalanceMonitoring true set enableScheduledEventDraining false set

types for example my applications almost run in java and they require much memory so I choose R type and its family could be r xlarge ra xlarge etc Flexible of Availability Zone here I give the case of using EKS node group Configure multiple node groups scope each group to a single Availability Zone and enable the balance similar node groups feature in cluster autoscaler so that we will have at least each node in different zones and guarentee the HA Especially when the PVC is attached to an AZ the pod need to be start on a spot instance in same zone eg Create two node groups in different AZ using AWS cdk self eks cluster add nodegroup capacity id EksNodeGroupStateless capacity type eks CapacityType SPOT desired size disk size instance types ec InstanceType ra xlarge ec InstanceType r

r xlarge labels role worker type stateful lifecycle spot max size min size nodegroup name eks node group stateful node role worker role subnets ec SubnetSelection subnet type ec SubnetType PRIVATE availability zones ap northeast b Prepare individual instances for interruptions The best way for you to gracefully handle Spot Instance interruptions is to architect your application to be fault tolerant in EKS we can use HPA to ensure the number of available pods if one node down and use cluster autoscaler to request new node Max price We recommend that you do not specify a maximum price but rather let the maximum price default to the On Demand price A high maximum price does not increase your chances of launching a Spot Instance See EC Spot pricing modelRef ltag user id follow action
