You can install Helm charts on an OpenShift Container Platform cluster using the following methods:

  • The CLI.

  • The Developer perspective of the web console.

The Developer Catalog, in the Developer perspective of the web console, displays the Helm charts available in the cluster. By default, it lists the Helm charts from the Red Hat OpenShift Helm chart repository. For a list of the charts, see the Red Hat Helm index file.

As a cluster administrator, you can add multiple Helm chart repositories, apart from the default one, and display the Helm charts from these repositories in the Developer Catalog.
