Helm Charts

Overview

Helm is a software package manager that simplifies deployment of applications and services to OpenShift Container Platform clusters.

Helm uses a packaging format called charts. A Helm chart is a collection of files that describes the OpenShift Container Platform resources.

A running instance of the chart in a cluster is called a release. A new release is created every time a chart is installed on the cluster.

Each time a chart is installed, or a release is upgraded or rolled back, an incremental revision is created.

Key features

Helm provides the ability to:

  • Search through a large collection of charts stored in the chart repository.
  • Modify existing charts.
  • Create your own charts with OpenShift Container Platform or Kubernetes resources.
  • Package and share your applications as charts.

You can use the Developer perspective in the web console to select and install a chart from the Helm charts listed in the Developer Catalog. You can create a Helm release using these charts, upgrade, rollback, and uninstall the release.
