About this class

Learning to build Kubernetes applications will open up career opportunities in high-demand roles in DevOps, cloud engineering & containerization roles. Using Python, this course teaches how to define application resources & use core primitives to build, monitor & troubleshoot scalable applications in Kubernetes ? including working with network plugins, security & cloud storage to deploy applications in a production environment.

Starting with a simple Python script, this course will show you how to define application resources and use core primitives to build, monitor and troubleshoot scalable applications in Kubernetes. Working with network plugins, security and cloud storage, you will be exposed to many of the features needed to deploy an application in a production environment.

The topics covered are directly aligned with the knowledge domains tested by the CKAD program, and will substantially increase students? ability to become certified.

In this live, instructor-led course you will learn with a cohort of fellow IT professionals while gaining key knowledge & skills related to the Certified Kubernetes Application Developer (CKAD) certification exam. Course enrollment includes:

  • FREE CKAD exam registration: 12 months to schedule with one retake
  • FREE CKAD exam simulator: 2 attempts
  • 12-month access to course materials

What you'll be able to do

  • Kubernetes Architecture
  • Build
  • Design
  • Deployment Configuration
  • Security
  • Exposing Applications
  • Troubleshooting

Before you attend

To get the most out of this course, you should have: Basic Linux command line and file editing skills and be familiar with using a programming language (such as Python, Node.js, Go). Knowledge of Cloud Native application concepts and architectures is helpful for this course. Please note, Kubernetes Administration (LFS458) is not a pre-requisite for this course. There is overlap in the course materials as each one is designed to stand alone and aligns with the related exams. .
