Syllabus

Docker and Container Essentials

This module introduces the fundamentals of container technology, focusing on Docker's core concepts, installation, and practical usage. Learners will gain hands-on experience managing containers, accessing services, and troubleshooting using essential Docker commands. By the end, you'll be equipped to set up Docker on Ubuntu and interact with containers through the command line.

Deploying Kubernetes Using KinD

This module guides learners through setting up and managing Kubernetes clusters using KinD (Kubernetes in Docker). You will explore cluster architecture, node images, multi-node configurations, storage provisioning, and traffic flow with HAProxy, gaining hands-on experience in deploying and customizing local Kubernetes environments.

Kubernetes Bootcamp

This module introduces key Kubernetes resources and control plane components, including ConfigMaps, Endpoints, Priority Classes, and Role Bindings. Learners will explore how these resources interact to manage configuration, access, and scheduling within a Kubernetes cluster. Practical examples and command-line usage are provided to build foundational skills for cluster management.

Services, Load Balancing, and Network Policies

This module explores how Kubernetes manages service discovery, load balancing, and network security. Learners will gain hands-on experience with DNS-based service resolution, configuring different types of load balancers, and implementing network policies to control traffic flow and enhance cluster security.

External DNS and Global Load Balancing

This module explores advanced DNS management and global load balancing in Kubernetes environments. Learners will configure CoreDNS with ETCD, integrate ExternalDNS for dynamic service discovery, and implement global load balancing using K8GB and custom resources. Practical examples demonstrate how to connect Kubernetes DNS with enterprise systems and customize deployments for multi-cluster scenarios.
