Helm Application Management

Last updated: 2020-04-26 19:23:06

    Scenario

    You can create, delete, and modify Helm applications in the console. You can also perform such operations on the Helm CLI after installing the Helm client locally and connecting it to a cluster.

    Prerequisite

    • A TKE cluster is available, and at least 0.28 cores and 180 MiB memory have been reserved for the installation of Helm tiller components.
    • Has Helm application management function enabled.
    • Only clusters with Kubernetes v1.8 or later are supported.

    Notes

    • If the Helm application management feature is not enabled, apply to enable it in Helm Applications.
    • After the Helm application management feature is enabled, Helm tiller-related components will be installed in the cluster.

    Directions

    Creating a Helm application

    1. Log in to the Tencent Cloud TKE console and click Clusters in the left sidebar.
    2. At the top of the "Helm Application" page, choose Location > Run Cluster, and click Create.
    3. On the "Create a Helm Application" page, configure the following parameters as needed.
      • Application Name: enter a custom name.
      • Origin: it can be a third-party repository, an official Helm repository, or a self-built Helm repository.
        • Download Address: enter the download address for Chart as needed. Note that the value must start with http and end with .tgz, for example, http://139.199.162.50/test/nginx-0.1.0.tgz.
        • Type: both the public and private types are available. Select one of them as needed.
      • Key-Value: you can replace the default configuration of the Chart package by setting custom parameters such as image.repository = nginx.
