Mumshad Mannambeth – Certified Kubernetes Administrator (CKA) with Practice Tests (Download)

What You’ll Master

Core Kubernetes Architecture

Understand cluster architecture components including ETCD, Kube-API Server, Kube Controller Manager, Kube Scheduler, Kubelet, and Kube Proxy. Learn how these elements work together to orchestrate containerized workloads.

Cluster Design & Installation

Design production-ready Kubernetes clusters considering high availability requirements. Configure ETCD in HA mode and choose appropriate infrastructure. Learn to build clusters from scratch using “The Hard Way” methodology for deep architectural understanding.

Workload Management

Deploy and manage Pods, ReplicaSets, Deployments, and Services. Master namespaces for resource isolation, implement rolling updates and rollbacks, and configure multi-container pods with init containers and design patterns.

Advanced Scheduling

Control pod placement using manual scheduling, labels and selectors, taints and tolerations, and node affinity. Configure resource limits, DaemonSets, static pods, and multiple schedulers. Implement autoscaling with Horizontal Pod Autoscaler (HPA) and Vertical Pod Autoscaler (VPA).

Security Hardening

Implement TLS certificates, configure authentication and authorization using RBAC, manage service accounts, and apply security contexts. Create network policies to control pod-to-pod communication and secure container images.

Storage Configuration

Work with persistent volumes and persistent volume claims. Configure storage classes for dynamic provisioning and understand the Container Storage Interface (CSI) for integrating storage solutions.

Networking Deep Dive

Master pod networking, CNI plugins (including Weave), service networking, and DNS configuration with CoreDNS. Implement Ingress controllers for external access and explore the new Gateway API introduced in 2025 updates.

Cluster Maintenance

Perform OS upgrades with minimal downtime, execute cluster version upgrades, and implement backup and restore procedures for ETCD. Understand Kubernetes release cycles and version management.
