K8s Practice #6: Operations Checklist — Upgrades / Backup,Recovery / Cost / Security
The last post in the K8s Practice series. Bringing up a cluster and operating it safely for a year are different kinds of work. This post organizes the EKS upgrade cycle, node group replacement pattern, RDS automated backup and PITR, cost management with Karpenter and Spot, and regular security checks with kube-bench and Trivy. It also includes a retrospective of the 6-post K8s Practice series and the full 26-post K8s track.
K8s Practice #1: EKS Cluster Setup — Terraform / eksctl / IRSA / Addons
The first post in the K8s Practice series. We follow the path of building a real operational cluster rather than a toy abstraction. Defining the VPC and EKS cluster with Terraform, setting up node groups and IRSA, laying on the essential addons (VPC CNI, CoreDNS, kube-proxy, EBS CSI), and comparing eksctl as a faster setup option along the way. The starting point for the imaginary service myshop-api used throughout the 6-post series.
