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.

Skills Gained

In this course you’ll learn how to:

  • Containerize and deploy a new Python script
  • Configure the deployment with ConfigMaps, Secrets and SecurityContexts
  • Understand multi-container pod design
  • Configure probes for pod health
  • Update and roll back an application
  • Implement services and NetworkPolicies
  • Use PersistentVolumeClaims for state persistence
  • And more

Prerequisites

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). A 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.

This is my second class with this Tech Data ExitCertified Personnel. I learned so much in BigFix Foundations and BigFix Inventory. Very well organized training instructors and well organized course contents and labs. I am glad I have attended.

It would be better if the classroom had two power point screens so the instructor could have two screens shown to the class at the same time to reduce confusion switching back and forth

I felt the instructor had a wealth of knowledge. I would have liked to get access to the class materials sooner and have more time to access the labs. I would prefer to go through the lab in tandem with the materials

Fantastic and great training. Tons of hands-on labs to really make you understand the material being thought.
