This four-day instructor-led class is designed to help IT professionals prepare for the Certified Kubernetes Application Developer (CKAD) exam.
This Track Includes:
Kubernetes for App Developers (LFD459) – 3 Days
Kubernetes for App Developers (LFD459)
Duration
3 Days
Description
Kubernetes is a high-velocity open source orchestration tool to deploy, scale, and update containerized applications. This course will teach you how to containerize, host, deploy, and configure an application in a multi-node cluster.
The topics covered are directly aligned with the knowledge domains tested by the Cloud Native Computing Foundation Certified Kubernetes Application Developer (CKAD) Program, and will substantially increase students’ ability to become certified.
Objectives
This course will teach you how to containerize, host, deploy, and configure an application in a multi-node cluster. Starting with a simple Python script, you will 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.
