1

What is a Helm chart?

Answer

A Helm chart is a reusable package containing all the necessary files to deploy an application on Kubernetes. It groups YAML manifests, parameterizable templates, and configuration values in a standardized structure. Charts enable sharing and versioning complex applications in a consistent and reproducible manner.

2

What is the command to install a Helm chart?

Answer

The helm install command deploys a chart on the Kubernetes cluster by creating a new release. It accepts a release name and the path or reference of the chart to install. This command initializes the resources defined in the chart and deploys them according to configured values, while maintaining history for future rollbacks.

3

Which file contains the default configuration values of a Helm chart?

Answer

The values.yaml file contains all default configuration values used by the chart's templates. This file centralizes configurable parameters such as image names, replicas, resources, or ports. Users can override these values during installation with the --values or --set option to adapt the deployment to their environment.
