Manage releases by using Helm - User Guide for Kubernetes Clusters| Alibaba Cloud Documentation Center

Container Service for Kubernetes (ACK) integrates the package manager Helm to help you deploy applications to the cloud in an efficient manner. You can install a chart multiple times in a Kubernetes cluster. Each time you install a chart, a release is created. This requires you to manage release versions. To meet this requirement, ACK provides the release feature that allows you to manage applications deployed by using Helm in the ACK console.

Prerequisites

An ACK cluster is created. For more information, see Create an ACK managed cluster.
An application is installed by using Helm on the App Catalog tab. For more information, see Use Helm to simplify application deployment. In this example, an application named tf-model is deployed.

View release details

Log on to the ACK console.
In the left-side navigation pane of the ACK console, click Clusters.
On the Clusters page, find the cluster that you want to manage and click the name of the cluster or click Details in the Actions column. The details page of the cluster appears.
In the left-side navigation pane of the details page, choose Applications > Helm.
On the Helm page, find the release that you want to manage and click View Details in the Actions column.
On the details page of the release, you can view information about the current release and the previous releases, such as resource names, resource types, and YAML files.

Note To view the status of a resource, click the name of the resource to go to the Kubernetes dashboard page.
Click the Parameters tab. You can view the parameters of the Helm chart.

Update a release

Log on to the ACK console.
In the left-side navigation pane of the ACK console, click Clusters.
On the Clusters page, find the cluster that you want to manage and click the name of the cluster or click Details in the Actions column. The details page of the cluster appears.
In the left-side navigation pane of the details page, choose Applications > Helm.
On the Helm page, click Update in the Actions column for the release that you want to modify.
In the Update Release panel, modify the parameters based on your requirements and click OK to update the release.
(Optional) On the Helm page, find the release that you want to manage and click View Details in the Actions column. On the page that appears, click the History tab. Then, you can select a release on this tab and click Roll Back in the Actions column to perform a rollback.

Delete a release

Log on to the ACK console.
In the left-side navigation pane of the ACK console, click Clusters.
On the Clusters page, find the cluster that you want to manage and click the name of the cluster or click Details in the Actions column. The details page of the cluster appears.
In the left-side navigation pane of the details page, choose Applications > Helm.
On the Helm page, find the release that you want to delete and click Delete in the Actions column.
In the Delete dialog box, select Clear Release Records and click OK. After the release is deleted, the resources of the release are deleted, including the Services and Deployments.

Note If you clear Clear Release Records, the deletion of the release does not take effect. You can still find the release in the release list. If you create another release with the same name, a release name conflict occurs.
