Acerca del curso
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.
Preparation for the exam: Certified Kubernetes Application Developer (CKAD)
The topics covered are directly aligned with the knowledge domains tested by the CKAD program, and will substantially increase students’ ability to become certified.
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 (such as is taught in our free Introduction to Kubernetes edX MOOC) 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.
