Before you install monitoring, ingress or a database on a cluster, you need to find the right chart, pick a version and know what it will pull in. The add-on catalog is the one place in Ankra that answers this for every Helm registry your organisation has connected. Open it from Add-ons in the main sidebar.

​
Add-ons and charts

The catalog shows two kinds of cards:
  • Add-ons - a named tool such as Grafana or cert-manager, with a description, category and links. An add-on groups every chart that deploys it, using match rules (chart names, keywords and home URL prefixes), so the same tool published in several registries appears once. A card is marked Public when Ankra curates it for every organisation, or Organisation when your organisation curated it.
  • Charts - a Helm chart from one of your registries. Charts that no add-on matches still appear, as uncurated charts.
A card that is already installed on one of your clusters shows Installed, or Installed ×N when it is installed more than once.

​
Find what you need

Search matches display names, add-on names and the names of the charts an add-on groups. Three filters narrow the list: When the catalog is empty or a chart you expect is missing, Manage registries takes you to the registries your organisation has connected. Adding a Helm or OCI registry there is covered in Registries; its charts are indexed and appear in the catalog.

​
What a chart page shows

Selecting a chart opens it at a specific version, with a version selector and five tabs: The License field shows the license’s SPDX identifier (for example Apache-2.0). Ankra reads it from the artifacthub.io/license annotation in Chart.yaml, or detects it from a LICENSE or COPYING file in the package, and says which. Copyleft licenses such as the GPL and AGPL family are highlighted, so a license that carries obligations for derived works stands out before you deploy.

​
Install from the catalog

Add-ons run on a cluster as part of a Stack: you add the chart to a Stack, set its values, and Ankra installs it with Helm and keeps it reconciled. The steps are in Install add-ons. From a chart’s Overview you can also use Install with AI, which asks the AI Assistant to help you pick a cluster and configure the installation.

​
Curate your own add-ons

Create add-on defines an add-on for your organisation: a name, display details, a category and the match rules that link charts to it. On an add-on curated by Ankra, customising it creates your organisation’s own copy, which takes precedence over the global one in your catalog. An add-on’s page lists the charts that resolve to it, lets you link or unlink a chart by hand, and shows the clusters it is installed on. Two guides cover sharing what you build:
  • Publishing add-ons - propose an add-on your organisation curated to the global catalog every organisation sees.
  • Publishing applications as add-ons (Closed Beta) - snapshot an application’s manifests as a versioned add-on your organisation can install on any cluster.
