Under Add tags (Optional), add metadata to the role by attaching tags as key–value pairs. The EKS API also does not support adding or removing the remote access EKS# Client# class EKS. desired_size: The number of instances in the EKS cluster node group. An EKS cluster with v1. Examples. This configures the managed node group with a taint that repels all pods that don't have a matching toleration. They have used 'non-managed nodes' (which I think EKS docs call self-managed) but they want to start using a managed node group but they need to control the nodes' IPs to allow setting up firewall rules to restrict on-premises access to the specific pod(s) Difference between EKS managed node group and self-managed node group. When Kubernetes is a scalable container orchestrator that helps you build fault-tolerant, cloud native applications. Still, I'm confused, what is the purpose and objective of a node group as to why it exists? It seems like node group doesn't exist on kubernetes and only on eks.
