Pull Helm Charts from OCI Registry

Introduction

Devtron supports the installation of Helm charts from both: Helm repos and Container/OCI registries. Unlike Helm repos, OCI registries do not have an index file to discover all the charts. However, Devtron makes it easier for you to populate your charts from multiple sources to the chart store.

Prerequisites

• Helm Chart(s)

• OCI-compliant Registry (e.g. Docker Hub and many more)

You must add your OCI registry to Devtron with the Use as chart repository option enabled.

Tutorial

Populating your Charts to the Chart Store

1. Go to Global Configurations → Container/OCI Registry.

2. Search your OCI registry in the list, and click it.

3. In the List of repositories, add the chart repo(s). The format should be username/chartname. You can find the username from your registry provider account.

   
4. Click Save or Update.

5. From the left sidebar, go to Chart Store.

6. You can find your chart(s) either by using the search bar or by selecting your chart source.

   

You have successfully pulled your charts to the chart store.

Removing your Chart from the Chart Store

1. Go to your OCI registry settings in Devtron.

2. In the List of repositories field, remove the unwanted chart repo.

   
3. Click Update.
