Helm Training Courses and Certification by DevOpsSchool

What is Helm?

Helm is an open-source package manager for Kubernetes. It allows developers to easily manage and deploy applications on a Kubernetes cluster. Helm uses a concept called charts, which are packages of Kubernetes resources that can be easily installed, upgraded, or deleted.

Helm’s main features include:

  • The ability to manage multiple Kubernetes resources as a single package, called a chart.
  • The ability to version charts, allowing for easy rollbacks and upgrades.
  • Support for chart dependencies, allowing multiple charts to be installed and managed together.
  • The ability to define and manage default configuration values for a chart.
  • Support for templating, allowing charts to be customized without modifying the chart itself.

Prerequisite of helm course

A Helm course typically has the following prerequisites:

  • Basic knowledge of Kubernetes: Helm is used to manage applications on a Kubernetes cluster, so a basic understanding of – Kubernetes concepts such as pods, services, and deployments is necessary.
  • Familiarity with command-line interface (CLI): Helm is primarily used via the command-line, so a basic understanding of using a CLI is required.
  • Familiarity with Git: Helm charts are typically stored in Git repositories and versioned, so a basic understanding of Git is necessary.
  • It’s also recommended to have the following skills before taking a Helm course:
  • Experience with containerization: Helm is used to deploy and manage containerized applications on a Kubernetes cluster, so experience with containerization technologies such as Docker is beneficial.
  • Experience with YAML: Helm charts are written in YAML, so experience with this markup language is beneficial.
