Description

Helm helps you manage Kubernetes applications — Helm Charts help you define, install, and upgrade even the most complex Kubernetes application.

Charts are easy to create, version, share, and publish — so start using Helm and stop the copy-and-paste.

Helm is a tool for managing Kubernetes packages called charts. Helm can do the following:

Create new charts from scratch
Package charts into chart archive (tgz) files
Interact with chart repositories where charts are stored
Install and uninstall charts into an existing Kubernetes cluster
Manage the release cycle of charts that have been installed with Helm

As a developer of Infrastructure enthusiast dealing with deployment in Kubernetes cluster then this course is for you, we have condensed down years of learning covering only what's needed to get started with Helm.

This course is for any one who has dealt with Kubernetes deployment into one or more projects and would like to learn the best practises of package management via HELM Deployment.

Adding HELM knowledge in your portfolio will not only increase the number of opportunities you will get but also your knowledge around the best & efficient way to automate kubernetes object deployment like services, pods, deployment, statefulsets.

Be it deployment of your custom API or ELK stack, this course will help you to learn nuts & bolts of HELM and can assure you will be able to apply the learning right from the session1.

What will you learn over the next few hours and How the course is shaped?
