Helm is a Kubernetes package managing tool, widely using in the industry. Developers can create Kubernetes packages with Helm and install in repositories same as docker images. So, whenever developers want to install the package, you can simply pull the chart from the repository and proceed.

In Docker, we build docker images and store them in a remote repository such as Docker Hub, GCR or ECR. Same with Helm you can generate Kubernetes packages with Helm called Charts. These charts can package into archive (tgz) files and store them in a remote or local repository.

There are 03 main components in Helm.

1. Chart — a bundle of information necessary to create an instance of a Kubernetes application
2. Config — contains configuration information that can be merged into a packaged chart to create a releasable object
3. Release — a running instance of a chart, combined with a specific config

The Helm client and library is written in the Go programming language.

The library uses the Kubernetes client library to communicate with Kubernetes. Currently, that library uses REST+JSON. It stores information in Secrets located inside of Kubernetes. It does not need its own database.

Configuration files are, when possible, written in YAML.

Let’s try to create a Helm package.
