Last updated:2021-05-11 10:41:36

KCE integrates the features of Helm. You can manage Helm applications in the KCE console in a visualized manner.

Prerequisites

  • A cluster is created. The Kubernetes version of the cluster is later than 1.8.
  • The cluster resources are sufficient. The Helm service occupies 0.25 CPU core and 160 MiB memory in the cluster.

Enable the Helm service

Log in to the KCE console, click Helm Application in the left navigation pane, and then select the target cluster from the Cluster drop-down list. If the Helm service is not enabled, click Apply for install.

Relevant components such as Tiller are installed in the cluster when you enable Helm. After Helm is enabled, you can use relevant features of Helm. For example, you can create Helm applications in the KCE console.
