Application Metadata

To display more information about custom applications in the UI, define a metadata.yaml file for each application in the git repository.

You can define how custom applications display in the DKP UI by defining a metadata.yaml file for each application in the git repository. You must define this file at services/<application>/metadata.yaml for it to process correctly.

You can define the following fields:

Field Default Description
displayName falls back to App ID Display name of the application for the UI.
description “” Short description, should be a sentence or two, displayed in the UI on the application card.
category general 1 or more categories for this application. Categories are used to group applications in the UI.
overview Markdown overview used on the application detail page in the UI.
icon Base64 encoded icon SVG file used for application logos in the UI.

None of these fields are required for the application to display in the UI.

Here is an example metadata.yaml file:

displayName: Prometheus Monitoring Stack
description: Stack of applications that collect metrics and provides visualization and alerting capabilities. Includes Prometheus, Prometheus Alertmanager and Grafana.
category:
  - monitoring
overview: >
  # Overview
  A stack of applications that collects metrics and provides visualization and alerting capabilities. Includes Prometheus, Prometheus Alertmanager and Grafana.

  ## Dashboards
  By deploying the Prometheus Monitoring Stack, the following platform applications and their respective dashboards are deployed. After deployment to clusters in a workspace, the dashboards are available to access from a respective cluster's detail page.

  ### Prometheus

  A software application for event monitoring and alerting. It records real-time metrics in a time series database built using a HTTP pull model, with flexible and real-time alerting.

  ### Prometheus Alertmanager
  A Prometheus component that enables you to configure and manage alerts sent by the Prometheus server and to route them to notification, paging, and automation systems.

  ### Grafana
