Import a Helm Repository

KubeSphere builds app repositories that allow users to use Kubernetes applications based on Helm charts. App repositories are powered by OpenPitrix, an open source platform for cross-cloud application management sponsored by QingCloud. In an app repository, every application serves as a base package library. To deploy and manage an app from an app repository, you need to create the repository in advance.

To create a repository, you use an HTTP/HTTPS server or object storage solutions to store packages. More specifically, an app repository relies on external storage independent of OpenPitrix, such as MinIO object storage, QingStor object storage, and AWS object storage. These object storage services are used to store configuration packages and index files created by developers. After a repository is registered, the configuration packages are automatically indexed as deployable applications.

This tutorial demonstrates how to add an app repository to KubeSphere.

Prerequisites

Add an App Repository

  1. Log in to the web console of KubeSphere as ws-admin. In your workspace, go to App Repositories under App Management, and then click Add.

    app-repo

  2. In the dialog that appears, specify an app repository name and add your repository URL. For example, enter https://charts.kubesphere.io/main.

    app-info-dialogue

    • Name: Set a simple and clear name for the repository, which is easy for users to identify.

    • URL: Follow the RFC 3986 specification with the following three protocols supported:

      • S3: The URL is S3-styled, such as s3.<region>.amazonaws.com for the access to Amazon S3 services using the S3 interface. If you select this type, you need to provide the access key and secret.
      • HTTP: For example, http://docs-repo.gd2.qingstor.com. The example contains a sample app NGINX, which will be imported automatically after the repository is created. You can deploy it from app templates.
      • HTTPS: For example, https://docs-repo.gd2.qingstor.com.

        Note

        If you want to use basic access authentication in HTTP/HTTPS, you can use a URL with a style like this: http://username:[email protected].
    • Description: Give a brief introduction of main features of the app repository.

  3. After you specify required fields, click Validate to verify the URL. You will see a green check mark next to the URL if it is available and click OK to finish.

    Note

    • In an on-premises private cloud environment, you can build your own repository based on ChartMuseum. Then, you develop and upload applications to the repository and deploy them on KubeSphere for your own needs.

    • If you need to set up HTTP basic access authentication, you can refer to this document.

  4. The repository appears in the repository list below after imported and KubeSphere automatically adds all apps in the repository as app templates. When users choose to deploy apps using app templates, they can see apps in this repository. For more information, see Deploy Apps from App Templates.
