A Helm package is a compressed archive file that contains a packaged Helm chart. It is created by running the helm package command, which inputs a Helm chart directory and generates a .tgz file.
The Helm package bundles all the necessary files and resources to deploy an application on a Kubernetes cluster using Helm. It includes the chart’s templates, configuration files, metadata, and any additional files specified in the chart directory.
This page explores how to use the helm shell command with practical examples. Once you have your helm Chart ready for shipping (your build is ready), you can create the archive or package using the helm package command, the command to pack is helm package.
Helm package command syntax:
helm package <CHART-NAME>This should be done from the Chart’s parent directory.
