Manage Helm Repository¶

The Helm repository is a repository for storing and publishing Charts. The Helm application module supports HTTP(s) protocol to access Chart packages in the repository. By default, the system has 4 built-in helm repos as shown in the table below to meet common needs in the production process of enterprises.

In addition to the above preset repositories, you can also add third-party Helm repositories yourself. This page will introduce how to add and update third-party Helm repositories.

Prerequisites¶

• Integrated the Kubernetes cluster or created the Kubernetes cluster, and you can access the UI interface of the cluster.

• Created a namespace, user, and granted NS Admin or higher permissions to the user. For details, refer to Namespace Authorization.

• If using a private repository, you should have read and write permissions to the repository.

Introduce third-party Helm repository¶

The following takes the public container repository of Kubevela as an example to introduce and manage the helm repo.

1. Find the cluster that needs to be imported into the third-party helm repo, click the cluster name, and enter cluster details.

   

2. In the left navigation bar, click Helm Apps -> Helm Repositories to enter the helm repo page.

   

3. Click the Create Repository button on the helm repo page to enter the Create repository page, and configure relevant arguments according to the table below.

   • Repository Name: Set the repository name. It can be up to 63 characters long and may only include lowercase letters, numbers, and separators -. It must start and end with a lowercase letter or number, for example, kubevela.
   • Repository URL: The HTTP(S) address pointing to the target Helm repository. For example, https://charts.kubevela.net/core.
   • Skip TLS Verification: If the added Helm repository uses an HTTPS address and requires skipping TLS verification, you can check this option. The default is unchecked.
   • Authentication Method: The method used for identity verification after connecting to the repository URL. For public repositories, you can select None. For private repositories, you need to enter a username/password for identity verification.
   • Labels: Add labels to this Helm repository. For example, key: repo4; value: Kubevela.
   • Annotations: Add annotations to this Helm repository. For example, key: repo4; value: Kubevela.
