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.

# 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 Documentation - Overview](https://prometheus.io/docs/introduction/overview/)
### 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
A monitoring dashboard from Grafana that can be used to visualize metrics collected by Prometheus.
