IT Directors/Managers

Overview

All topics required by the CKAD exam, including:
Deploy applications to a Kubernetes cluster
Pods, ReplicaSets, Deployments, DaemonSets
Self-healing and observable applications
Multi-container Pod Design
Application configuration via Configmaps, Secrets
Administrate cluster use for your team
A systematic understanding of Kubernetes architecture
Troubleshooting and debugging tools
Kubernetes networking and services

Kubernetes is a Cloud Orchestration Platform providing reliability, replication, and stability while maximizing resource utilization for applications and services. By the conclusion of this hands-on training, you will go back to work with all necessary commands and practical skills to empower your team to succeed, as well as gain knowledge of important concepts like Kubernetes architecture and container orchestration. We prioritize covering all objectives and concepts necessary for passing the Certified Kubernetes Application Developer (CKAD) exam. You will command and configure a high availability Kubernetes environment (and later, build your own!) capable of demonstrating all ?K8s'' features discussed and demonstrated in this course. Your week of intensive, hands-on training will conclude with a mock CKAD exam that matches the real thing.
