Helm for absolute beginners
Helm for absolute beginners. Learn how to manage applications with Helm, the package manager for Kubernetes.
Course Description
Kubernetes offers a rich set of features that facilitate application deployment, scaling, and operations.
An applications in Kubernetes may have different objects such as deployments, services, persistant volume claims, persistant volumes, secrets, ConfigMaps and more.
Each object needs its own YAML file for its configuration. we can put the configuration for all the Kubernetes objects in a single YAML file, but this is not ideal and not recommended.
Although these objects are part of a single application, Kubernetes doesn’t consider them as a group of objects parts of the same application, and manages each object independently from the others.
For example when deploying this application into a Kubernetes cluster, we create the objects one after the other, by executing the kubectl create command followed by the name of the manifest file for each object
The same when updating or deleting the application, the Kubernetes objects parts of this application are treated separately, and this makes the process of deploying and maintaining applications in Kubernetes a boring and tedious task.
Helm solves these problems and reduces this complexity, through the concept of Helm charts.
In this course, we will learn how does Helm make the process of deploying applications in Kubernetes much easier. We will practice also working with Helm and the Helm CLI to manage applications in Kubernetes.
