EKS Cluster Auto Scaling (Kubernetes Autoscaler | EKS Cluster Autoscaler | EKS Autoscale Nodes)
Source: YouTube · Anton Putra · published Jun 10, 2021 · 20:36
This video demonstrates how to set up Kubernetes Cluster Autoscaler with EKS instance groups, showing that AWS recommends managed node groups for their automatic discovery and graceful termination capabilities 0:09-0:16.
Key Takeaways:
• Cluster Autoscaler requires specific labels on AWS autoscaling groups: "cluster-autoscaler-enabled=true" and "cluster-autoscaler" with the cluster name 2:59-3:18
• Instance groups need different min/max capacities to allow the autoscaler to adjust 3:53-4:07
• An OpenID Connect provider and IAM role are required for the autoscaler to work with EKS 4:14-6:48
• The autoscaler version must match the Kubernetes cluster version 9:14-9:51
• Testing showed the autoscaler both adding nodes for pending pods and removing unneeded nodes 14:40-20:17
The Cluster Autoscaler effectively scales EKS clusters up and down based on workload demand when properly configured 20:09-20:11.

in this video we're going to talk about how to auto scale eks instance groups using kubernetes cluster after scalar we will use both managed and unmanaged eks node groups however adws recommends using managed instance groups since they come with the automatic after scale group discovery and graceful node termination all right let's get started first of all we need to create the ecs cluster i'm gonna be using ectl but you can use terraform or you can even use the adwords console to create the cluster all right so to use the castile we need to define the config first i'm going to give it a name anton putra that's going to be the class name and this is very important for us we need to define the version for our cast cluster it's going to be 120 and in later we have to match with um cluster af…
