What’s good – Spot instances are available at a discount of up to 90% off compared to On-Demand pricing. For inherently fault tolerant workloads such as Fargate, Auto Scaling Groups, CI/CD, ECS, EKS, Kubernetes, EMR nodes, Sage Maker trainers and non production workloads, you can use Spot Instances to supplement your On-Demand Instances. FWIW, it seems that if you're using a Launch Template (custom userdata) and a Managed Node Group, you still can't request Spot instances that way. I'm on the latest version of the aws provider 3.20.0 and I was able to launch spot instances using a aws_eks_node_group resource and a aws_launch_teamplate resource.

The managed node group handles Spot interruptions for you in the following way: the underlying EC2 Auto Scaling group is opted-in to Capacity Rebalancing, which means that when one of the Spot Instances in your node group is at elevated risk of interruption and gets an EC2 instance rebalance recommendation, it will attempt to launch a replacement instance. The more instance types you configure in the managed node group, the more chances EC2 Auto Scaling has of launching a replacement Spot ...

AWS does not offer a free cluster in any way, you have a $72 monthly cost from the get go. On top of that their managed node groups do not offer spot instances currently, you'd have to use custom node groups to use spot instances which can be achieved with eksctl or EKS Terraform modules.

For example, if your EKS cluster worker nodes are deployed across "Two AZs and uses only a m5.xlarge instance type", then you are technocally only using two (2x1) spot capacity pools. A more robust alternative would be to use "Six AZs and multiple instance types (e.g. four)". The architecture deploys the EKS worker nodes over three AZs, and leverages three Auto Scaling groups - two for Spot Instances, and one for On-Demand. The Kubernetes Cluster Autoscaler is deployed on On-Demand worker nodes, and the AWS Node Termination Handler is deployed on all worker nodes.

Check out all the content in a "tag cloud" to get a quick view of the most talked about and popular subjects. You can filter the tags by category within the system. When the instance fleet launches, Amazon EMR tries to provision Spot Instances as specified by InstanceTypeConfig . Each instance configuration has a specified WeightedCapacity. When a Spot Instance is provisioned, the WeightedCapacity units count toward the target capacity. Amazon EMR provisions instances until the target capacity is totally fulfilled, even if this results in an overage. Deleting the node group that contains old instance type (replaced by the new node group with appropriate instance type). Terminating the instances first without removing the node group from the cluster will result to spawning new isntances with the old instance type which is not the goal that what I'm trying to accomplished.

I think your claim that they support spot via the EKS Node Group is incorrect. You have to be careful as their nodeGroup configuration block refers to directly created ASGs which can easily support spot, like this module's worker_groups. Their managedNodeGroup feature makes no mention of spot as it's not natively supported by the API.In AWS, it's widely accepted that a node group translates to an EC2 ASG — it's how eksctl (the official CLI tool for EKS) and kops provision instances, it's how EKS documentation recommends adding instances to your EKS cluster using CFn, and cluster-autoscaler is also integrated with it — so this, along with the ASG benefits that I described in the previous section, make ASG a perfect choice for running and managing our worker nodes.

Spot Instances and containers are an excellent combination, because containerized applications are often stateless and instance flexible. In this blog, I illustrate the best practices of using Spot Instances such as diversification, automated interruption handling, and leveraging Auto Scaling groups to acquire capacity. You then adapt these Spot Instance best practices to EKS with the goal of cost optimizing and increasing the resilience of container-based workloads. Add EC2 Workers - Spot We have our EKS Cluster and worker nodes already, but we need some Spot Instances configured as workers. We also need a Node Labeling strategy to identify which instances are Spot and which are on-demand so that we can make more intelligent scheduling decisions.

Aug 21, 2019 · One group is on-demand instances, and another node-group consists of Spot instances. Perhaps I prefer for the scheduler to use the Spot instances first. If they are filled, only then use the on-demand instances. This is actually quite tricky to do using the default scheduler. One way is to use an open-source project called k8-spot-scheduler. By default, the server agents will attempt to bind to ‘0.0.0.0’, but they will advertise the first private IP address on the node for other agents to communicate with them. If the other nodes cannot communicate with a node on this address, then the cluster will have a failed status.

Upon instance termination, when an instance is about to be detached from the group, Elastigroup will fetch the slave-clients and filter the id according to the hostname and instigate a draining procedure before the resource is detached in order to ensure complete draining and graceful termination.

As for availability, node count plays a more direct role in shaping this characteristic. The more nodes you have, the smaller the chance that you’ll experience a node failure so large that it disrupts your cluster’s availability.
