What is Helm?
Helm is a tool for managing Kubernetes packages (like APT/YUM in Linux world), and these packages are called charts.
What is Helm Chart?
The Helm chart is a bundle of information necessary to create an instance of a Kubernetes application.
What Helm can do?
- With Helm we can create new charts from scratch.
- Helm can package charts into chart archive (tgz) files
- Helm use to interact with chart repositories where charts are stored
- Helm is use to Install and uninstall charts into an existing Kubernetes cluster
- Manage the release cycle of charts that have been installed with Helm
What are Helm’s components?
Helm has two major components:
- Helm Client – It is a command-line client for end users. Helm client is used for local chart development, managing repositories and interacting with Tiller server.
- Helm Library – It provides the logic for executing all Helm operations. It interfaces with the Kubernetes API server and provides the capabilities like installing, upgrading and uninstalling charts in Kubernetes cluster.
Why Helm?
Helm helps create charts, and with this chart, we can deploy the application ( no need to write separate YAML files for each application manually). Helm charts contain templates for various Kubernetes resources that combine to form an application. A Helm chart can be customized when deploying it on different Kubernetes clusters.
