- The core objective of K8S-NET-105 is to empower learners with the ability to design, implement, troubleshoot, and optimize Kubernetes network configurations with unparalleled confidence. Each of the 1500 questions serves as a focused learning opportunity, ranging from conceptual multiple-choice to complex scenario-based problem-solving, which collectively fortify understanding across the entire networking stack. This method ensures that graduates possess not just theoretical knowledge but also a robust practical skillset to tackle any networking challenge within a Kubernetes ecosystem, preparing them for real-world operational demands.
Requirements / Prerequisites
- Foundational Kubernetes Understanding: Participants should possess a working knowledge of core Kubernetes concepts, including pods, deployments, replica sets, and basic cluster architecture. Familiarity with `kubectl` commands for interacting with a Kubernetes cluster is essential for engaging with the practical scenarios presented throughout the course.
- Basic Networking Fundamentals: A solid grasp of general networking principles, such as IP addressing, subnets, routing, firewalls, and common network protocols (TCP/IP, UDP), is crucial. This background will serve as a strong base for understanding how these concepts translate into the Kubernetes networking model.
- Linux Command Line Proficiency: Comfort navigating the Linux command line interface, including basic commands for file manipulation, process management, and network utilities, is expected. Many troubleshooting and configuration tasks within Kubernetes environments require strong command-line skills.
- YAML Syntax Familiarity: Given that Kubernetes resources are primarily defined using YAML, participants should be familiar with YAML syntax for creating and modifying configuration files. While not explicitly a programming course, understanding resource definitions is key.
Skills Covered / Tools Used
- Kubernetes Service Types & Lifecycle Management: Master the nuances of ClusterIP, NodePort, LoadBalancer, and ExternalName services, including their use cases, configuration, and troubleshooting for internal and external application exposure.
- CoreDNS Configuration & Service Discovery: Gain expertise in managing and debugging CoreDNS within Kubernetes, ensuring reliable service discovery for applications and understanding DNS resolution flow across the cluster.
- Ingress Controllers & Advanced Traffic Routing: Deep dive into setting up and configuring various Ingress controllers (e.g., NGINX, Traefik, HAProxy), defining Ingress resources for HTTP/HTTPS routing, path-based routing, host-based routing, and TLS termination.
- Container Network Interface (CNI) Plugin Deep Dive: Explore the architecture, configuration, and operational differences of popular CNI plugins such as Calico, Flannel, Cilium, and Weave Net, understanding their impact on network performance and policy enforcement.
- Kubernetes Network Policies for Security: Learn to design and implement robust network segmentation using `NetworkPolicy` resources to control ingress and egress traffic between pods, namespaces, and external endpoints, enhancing cluster security.
- Advanced Load Balancing & External Access: Understand internal load balancing strategies, integration with cloud provider load balancers, and advanced techniques for exposing applications securely and efficiently to the outside world.
- Network Troubleshooting Methodologies: Develop systematic approaches to diagnose and resolve complex network issues within Kubernetes, utilizing tools like `kubectl debug`, `tcpdump`, `netstat`, `ss`, `dig`, `curl`, and CNI-specific debugging utilities.
- Network Observability & Monitoring: Principles for monitoring Kubernetes network traffic, analyzing network performance metrics, and leveraging logging solutions to proactively detect and debug network-related anomalies and bottlenecks.
- IP Address Management (IPAM) in K8s: Understand how CNI plugins handle IP address allocation to pods and services, and how to troubleshoot IP exhaustion or assignment conflicts within the cluster.
- Practical Scenario Application & Problem Solving: Apply theoretical knowledge across 1500 unique questions and challenges, spanning various real-world scenarios to validate understanding and reinforce practical troubleshooting skills.
