GitOps for Kubernetes

Published by Pearson

Intermediate content levelIntermediate

Streamline your work deploying Kubernetes manifests with GitOps

  • Learn core GitOps skills
  • See how GitOps streamlines manual Kubernetes deployments so you can easily get CI/CD Kubernetes Manifests deployed
  • Uncover what GitOps is and the problems it solves
  • Learn to implement GitOps with real-world scenarios and labs

Kubernetes manifests are usually simple, but the more you have, the more complicated it can be to use them. GitOps helps you streamline this process when deploying manifests so building your applications isn’t a thorny process. With GitOps you can automate deployments based on source control and the code that lives inside of it.

This 5-hour live training will detail how GitOps takes code inside of source control and automatically deploys it as the desired state for the application running inside of your Kubernetes cluster. This training will emphasize how to take away the manual effort of deploying apps to Kubernetes and then how to automate the entire process using a Kubernetes Operator.

This is a quick way to learn the basics of GitOps so you can get started in a production environment using GitOps today.

What you’ll learn and how you can apply it

By the end of the live online course, you’ll understand:

  • The basics and intermediate concepts of GitOps
  • GitOps best practices and how to use GitOps in production
  • Knowledge and clarity around why GitOps is needed for every environment

And you’ll be able to:

  • Start working with GitOps on your own or at work
  • Explain why GitOps is a game changer for any company, big or small
  • Build GitOps solutions for yourself, your job, or the community

This live event is for you because...

  • You want the ability to learn a new and exciting cloud-native technology
  • You want to take your Kubernetes skills to the next level
  • You want to either scale up your current job as a Kubernetes/DevOps expert or get a new job

Prerequisites

  • Kubernetes knowledge (2+ years)
  • Knowledge of developer tools like IDEs, code editors like VS Code, GitHub, etc.
  • Hands-on experience with CI/CD

Course Set-up

  • A GitHub account. You can access the code for this course here
  • Access to a decently powerful machine (for example, an I7 with 16 GB of RAM)
  • Download VS Code
  • A Kubernetes cluster running anywhere or locally with something like Minikube or Docker Desktop
