Application Management

Feature Overview​

Application Management is a tool for managing applications in the openFuyao platform. It provides complete functions of deploying, updating, and uninstalling programs. In the current version, applications can be installed using Helm charts. The entire application list is displayed on the Application Management page and O&M management operations can be performed in the application list.

Applicable Scenarios​

Application Management supports complete O&M operations on released applications in Helm format.

  • Application information acquisition: You can obtain a list of applications, displaying the application name, status, and update time for each application, and filter and sort the applications. In addition, more information such as YAML, resource list, events, and monitoring is displayed on the details page.

  • Application lifecycle management: You can install, uninstall, upgrade, and roll back applications installed in a cluster.

  • Application installation using Helm charts: You can upload Helm charts of various types for application installation. You can also modify application parameters.

Supported Capabilities​

  • Basic information display: Basic information is displayed, including the application name, status, creation time, application template, template version, and update time. On the application list page, applications can be sorted by name or update time, and can be filtered by installation status.
  • O&M management: Users can perform application upgrades, rollback, and uninstallation. The upgrade function applies only to applications installed from the openFuyao application market. Users can view application resources (such as logs and events) and modify configurations (in YAML format).

Highlights​

Application Management supports lifecycle management of applications. You can install, deploy, upgrade, uninstall, and roll back applications through simple and intuitive operations. In addition, you can view application resources and logs, and monitor and observe applications.

Implementation Principles​

Figure 1 Implementation principles

The monitoring data in Application Management comes from the monitoring components of the openFuyao platform. Before using the application monitoring function, ensure that the monitoring components of the platform are running properly. For details, see Monitoring.

Using the Application Management Function​

In the left navigation pane, choose Application Management. The Application Management page is displayed. On this page, you can view the deployed application instances, including the application name, status, and update time.

Click an application name. On the application details page that is displayed, view the application details, including details, YAML, resources, logs, events, and monitoring information.

Upgrading an Application​

Prerequisites​

  • Kubernetes 1.28 and Helm 3.14.2 have been installed in the cluster.
  • The marketplace-service in the cluster is running properly.

Context​

Helm is a package manager in a Kubernetes cluster. Similar to apt used in Ubuntu and Yum used in CentOS, Helm helps you quickly install applications.

Restrictions​

The format of the software to be installed is Helm chart. Currently, only software uploaded to the repository can be installed.

Procedure​

  1. Method 1: On the Application Management page, click Input image description in the table and select Upgrade. The Upgrade page is displayed.

    Method 2: On the Application Details page, click Operation and select Upgrade. The Application Upgrade page is displayed.

  2. Select the target version for the upgrade from the Version drop-down list.

  3. Click OK.

You can roll back or uninstall an application by clicking Input image description in the Operation column on the list page or Operation in the upper-right corner on the details page and then selecting the desired option.

OperationDescription
Roll backThe application can be rolled back to an earlier version, which is identified by the version number and serial number. Currently, data rollback is not supported.
UninstallDue to Kubernetes' mechanisms, after an application is uninstalled, the files or data generated on the host's storage device or distributed storage device during the running of the application will not be forcibly removed. You need to manually remove the files or data to free up the storage space.
