Custom Kubernetes Component Launch Parameters

Last updated: 2020-10-29 09:57:05

    Overview

    To facilitate the configuration and management of Kubernetes component parameters in TKE clusters, Tencent Cloud supports custom Kubernetes component parameters. This document describes how to configure custom Kubernetes component parameters in clusters.

    Notes

    • To use custom Kubernetes component launch parameters, you need to submit a ticket to apply for it.
    • While submitting the ticket, you need to provide custom Kubernetes component launch parameters, including your account ID, cluster ID, and the component and component parameters.
    • For Kubernetes cluster version upgrade, due to the potential incompatibility of launch parameters after a Kubernetes version upgrade, major version upgrades will not retain the custom Kubernetes component parameters from your original cluster version. Therefore, you need to reconfigure custom Kubernetes component parameters.

    Directions

    1. Log in to the Tencent Cloud TKE console, and click Clusters in the left sidebar.
    2. On the "Cluster Management" page, click Create above the cluster list.
