Node Groups

EC2 node groups that provide compute capacity for your EKS cluster.

Node Groups are managed groups of EC2 instances that provide compute capacity for the EKS cluster. Each node group defines the instance type, scaling configuration, and optional taints or labels applied to its nodes.

If your Cluster Baseline uses EKS Auto Mode, AWS manages compute capacity automatically and node groups are not required.

Spec

Field	Description
Name	The name of the node group
Instance Type	The EC2 instance type for the nodes (e.g. m5.large)
Minimum Nodes	Minimum number of nodes in the group
Desired Nodes	Target number of nodes
Maximum Nodes	Maximum number of nodes (for autoscaling)
Disk Size	Root volume size in GB
Taints	Optional Kubernetes taints applied to all nodes in this group
Labels	Optional Kubernetes labels applied to all nodes in this group

Dependencies

Node Groups require a Cluster Baseline.
