The ACK App Marketplace integrates Helm and extends it with a console UI and Alibaba Cloud chart repositories. This topic explains how to deploy and update Helm charts from the console.
Key concepts
App Marketplace uses these Helm concepts:
| Concept | Description |
|---|---|
| Chart | A Helm package with all resources to run an application in a Kubernetes cluster, including container images, dependencies, and custom resource definitions (CRDs). |
| Repository | A collection of charts. App Catalog provides charts customized or optimized by ACK from open source versions. |
| Release | A running instance of a chart deployed to a cluster. Each deployment creates a new release. |
Prerequisites
Ensure that you have:
-
An ACK cluster
-
Permissions to deploy applications in the target namespace

Disclaimer
Some charts in App Catalog are based on open source versions and optimized for ACK. ACK provides full technical support for these charts in App Catalog. You must proactively upgrade software installed in your cluster and promptly fix defects caused by open source software.
