Karpenter EC2NodeClass: AMI, Subnets, and EBS Config

When your security team mandates a specific AMI, private subnets, custom security groups, and encrypted EBS, Karpenter's EC2NodeClass is exactly where all of that infrastructure detail lives. You'll learn: The core separation of concerns: NodePool defines what to provision (requirements, constraints); EC2NodeClass defines how (the cloud-provider infrastructure details) How to pin a specific AMI using amiSelectorTerms and lock nodes to private subnets via tag-based subnetSelectorTerms Configuring securityGroupSelectorTerms and enforcing EBS encryption through blockDeviceMappings in the EC2NodeClass spec How nodeClassRef wires a NodePool to a NodeClass — and why one NodeClass can back many NodePools, making AMI rotation straightforward Keywords: Karpenter EC2NodeClass, Karpenter NodePool vs NodeClass, Karpenter AMI selection, Karpenter private subnets, Kubernetes node provisioning security 🎧 Listen, then go deeper — DevOps & Cloud interview-prep ebooks at DevOpsInterview.Cloud
