Curriculum

Kubernetes Fundamentals & Core Concepts

This foundational section introduces the core architecture of Kubernetes, explaining the roles of the control plane and worker nodes. You'll gain proficiency with `kubectl` for interacting with your cluster and learn the importance of declarative YAML configurations. We'll cover fundamental concepts that underpin all Kubernetes operations, setting the stage for deeper application development topics, including a basic understanding of resource definitions and the Kubernetes API.

Pods, Workloads & Multi-Container Design Patterns

Dive deep into the fundamental unit of deployment in Kubernetes: Pods. This section covers their lifecycle, how to define them effectively using YAML, and manage them with labels and selectors. You'll learn about ReplicaSets for ensuring desired Pod counts and Deployments for managing application rollouts and rollbacks. We'll also explore advanced multi-container patterns like sidecars, init containers, and ambassador patterns to handle complex application requirements and workflows effectively.

Configuration and Secret Management

Master the crucial aspects of managing application configurations and sensitive data within Kubernetes. This section focuses on ConfigMaps for externalizing non-sensitive configuration values and Secrets for securely handling sensitive information like API keys or database credentials. You'll learn various methods for injecting these configurations into your application Pods, ensuring flexibility, maintainability, and security for your deployments through environment variables and volume mounts.

Resource Management, Health Checks & Observability

Optimize the performance and stability of your applications by understanding Kubernetes resource management. We'll cover how to define CPU and memory requests and limits, influencing Pod scheduling and ensuring fair resource allocation and Quality of Service (QoS). Explore Liveness and Readiness probes to ensure your applications are healthy and ready to serve traffic, along with an deeper introduction to foundational logging, monitoring, and debugging practices within a cluster.

Networking, Services & Ingress Controllers

Unravel the complexities of Kubernetes networking and service exposure. This section details the various Service types: ClusterIP for internal communication, NodePort for exposing services on worker nodes, and LoadBalancer for seamless cloud integration. You'll learn how Ingress controllers manage external HTTP/HTTPS traffic routing, including host and path-based routing, and how Network Policies secure inter-Pod communication, alongside Kubernetes' built-in DNS for service discovery.

Persistent Storage & Stateful Workloads

Understand how to provide durable storage for your stateful applications in Kubernetes. This section differentiates between Volumes, PersistentVolumes (PVs), and PersistentVolumeClaims (PVCs), explaining how they abstract underlying storage. We'll explore StorageClasses for dynamic provisioning and integrate with cloud-specific storage solutions like AWS EBS, Azure Disks, and Google Persistent Disks. StatefulSets, crucial for database deployments and other stateful workloads, will also be covered in detail.

Advanced Deployments & Cloud Platform Integration

Elevate your deployment strategies with advanced techniques like rolling updates, blue/green, and canary deployments for zero-downtime releases and safe feature rollouts. Discover Helm for streamlining application packaging and deployment. Finally, gain practical experience deploying and managing workloads on industry-leading managed Kubernetes platforms such as AWS EKS, Azure AKS, and Google Kubernetes Engine (GKE), understanding their specific integrations, operational nuances, and best practices for multi-cloud environments.
