How does the skill handle cluster upgrades?

It follows a structured, safe process: upgrading kubeadm, executing a version plan, and performing sequential rolling updates on control plane nodes before moving to workers.

Can this skill manage cloud-specific managed Kubernetes services?

Yes, it supports major cloud providers including EKS (AWS), AKS (Azure), and GKE (GCP), as well as self-managed kubeadm, kind, and minikube setups.

Does it support node-level troubleshooting?

Yes, it includes configurations for Node Problem Detectors and provides commands for diagnosing node pressure, connectivity issues, and container runtime errors.

Does it help with CKA or CKS certification prep?

Absolutely. The implementation patterns, command structures, and architectural guidance are aligned with Certified Kubernetes Administrator and Security Specialist standards.

Can I use this to automate etcd backups?

Yes, the skill provides both manual snapshot commands and automated CronJob templates to ensure your cluster state is backed up to persistent storage regularly.

Cloud Infrastructure

Manages production-grade Kubernetes cluster lifecycles, from initial bootstrap and high availability configuration to complex upgrades and disaster recovery.

About

This skill empowers developers and operators to architect, deploy, and maintain robust Kubernetes environments following industry best practices and CKA/CKS standards. It provides deep technical guidance for node lifecycle management, etcd backup/restore procedures, rolling cluster upgrades, and resource optimization through quotas and autoscaling. Whether you are managing local development clusters like kind or production-grade cloud environments like EKS, AKS, and GKE, this skill ensures operational excellence, high availability, and secure configuration at every layer of the stack.

Key Features

Structured rolling upgrade strategies for zero-downtime maintenance
Secure etcd backup orchestration and disaster recovery procedures
Advanced resource management using Namespace quotas and LimitRanges
Automated cluster bootstrapping and HA control plane configuration
Safe node lifecycle management including draining, cordoning, and taints
1 GitHub stars

Use Cases

Performing zero-downtime Kubernetes version upgrades across production worker nodes
Setting up automated etcd snapshots and backup verification routines for disaster recovery
Implementing cluster-wide resource limits and autoscaling to optimize cloud spending
