Kubernetes Certification Path on Dev & Platform Engineering Hub

CKS Deep Guide: Cluster Hardening & Runtime Security

Sun, 09 Aug 2026 16:15:00 +0000

The Certified Kubernetes Security Specialist (CKS) is the pinnacle performance exam testing your ability to secure containerized workloads, harden Kubernetes clusters, and detect runtime attacks.

CKAD Deep Guide: Application Design & Deployment Strategies

Sun, 09 Aug 2026 16:10:00 +0000

The Certified Kubernetes Application Developer (CKAD) exam tests your ability to design, build, expose, and troubleshoot cloud-native applications running inside Kubernetes clusters.

CKA Deep Guide: Cluster Architecture, Installation & etcd Backup

Sun, 09 Aug 2026 16:05:00 +0000

The Certified Kubernetes Administrator (CKA) exam is a 100% performance-based practical exam. You must execute complex administrative tasks directly inside Linux terminal command lines within a 2-hour window.

KCNA Deep Guide: Cloud Native Architecture & Exam Mastery

Sun, 09 Aug 2026 16:00:00 +0000

The Kubernetes and Cloud Native Associate (KCNA) certification tests your foundational understanding of the Cloud Native ecosystem, CNCF project landscape, and Kubernetes control plane mechanics.

CKAD Ep 5: Storage & Persistent Workloads

Sun, 09 Aug 2026 14:20:00 +0000

Containers are ephemeral by default—when a container restarts, all data written to its local filesystem is lost. On the CKAD exam, you must demonstrate how to attach persistent storage to Pods using PVCs and StorageClasses.

CKAD Ep 4: Services, Ingress & Network Policies

Sun, 09 Aug 2026 14:15:00 +0000

Services provide stable IP addresses for ephemeral Pods, Ingress controllers route HTTP/S domain traffic at Layer 7, and NetworkPolicies act as Pod-level firewalls. In this episode, we build production manifests for all three.

CKAD Ep 3: ConfigMaps, Secrets & Security Contexts

Sun, 09 Aug 2026 14:10:00 +0000

Decoupling application code from environment configuration and enforcing security policies is tested extensively on the CKAD exam. You must know how to pass ConfigMaps and Secrets into Pods as environment variables or volume mounts.

CKAD Ep 2: Deployments, Rollouts & Canary Releases

Sun, 09 Aug 2026 14:05:00 +0000

Deployments manage ReplicaSets to automate application rollouts and rollbacks. The CKAD exam requires you to perform image updates, scale replicas, track revision history, and execute emergency rollbacks within seconds.

CKAD Ep 1: Multi-Container Pod Patterns & Design

Sun, 09 Aug 2026 14:00:00 +0000

Multi-container Pod patterns allow containers to share storage and network namespaces to extend functionality without modifying application source code. Designing these patterns under time pressure is a core domain of the CKAD exam.

KCNA Ep 5: Cloud Native Security & GitOps Practices

Sun, 09 Aug 2026 13:25:00 +0000

Modern cloud-native operations rely on declarative security governance (RBAC, Network Policies) and automated continuous delivery (GitOps). In this final KCNA episode, we cover security fundamentals, GitOps workflows, and Service Meshes.

KCNA Ep 4: Telemetry, Observability & Monitoring

Sun, 09 Aug 2026 13:20:00 +0000

Observability allows engineers to infer the internal state of a complex distributed system based on its external outputs. For the KCNA exam, you must understand the Three Pillars of Observability and the CNCF tools that collect them.

KCNA Ep 3: Container Orchestration & Workload Primitives

Sun, 09 Aug 2026 13:15:00 +0000

Workload resources define how application containers are scheduled, scaled, and managed across a Kubernetes cluster. Understanding when to choose a Deployment vs a StatefulSet, DaemonSet, or Job is essential for the KCNA exam.

KCNA Ep 2: Kubernetes Fundamentals & Architecture

Sun, 09 Aug 2026 13:10:00 +0000

A Kubernetes cluster is divided into a Control Plane (the brain) and Worker Nodes (the muscle). Understanding how these components communicate via the declarative REST API is a core requirement for the KCNA exam.

KCNA Ep 1: CNCF Ecosystem & Cloud Native Architecture

Sun, 09 Aug 2026 13:05:00 +0000

The Kubernetes and Cloud Native Associate (KCNA) exam is a multiple-choice certification designed to test your foundational knowledge of the cloud-native ecosystem. In this first episode, we explore the CNCF landscape, cloud-native architecture patterns, and containerization principles.
