title: Deploy Helm Chart

This section introduces that how you deploy Helm Chart into multi-environments and clusters.
This section introduces how you deploy Helm Chart into multi-environments and clusters.
The typical usage of deploying Helm Chart is to integrate middleware, many from in [bitnami](https://github.com/bitnami/charts) or open-source application tools such as Gitlab, Jenkins in [Helm Official Repo](https://hub.helm.sh/). KubeVela can help you easily deploy these applications to any managed cluster and manage them.

Starting from here, you will learn to use the KubeVela Addons to install plug-ins. The Helm Chart is currently supported by the FluxCD addon. In addition to the Helm Chart, FluxCD addon also supports Kustomize.

- Repo Type: Git and Helm are supported. In this example, we choose Helm.
- Repo URL: Fill in the repo address you needed. we type in: https://charts.bitnami.com/bitnami. If you have configured the helm repo in [Integration](../how-to/dashboard/config/helm-repo) you can choose the repo directly.
- Chart: After fill Helm repo URL, will list all available charts in this field. You can choose one from the list, here we choose: redis.
- Version: After choose the helm chart, will list all available versions in this field. Choose one version of this chart, here we choose: 16.8.5.
- Values: After choose the version, will list all parameters of this helm Chart. Since we are using ACK cluster in the example, PV has a minimum capacity requirement, 15Gi. In the same way, other parameters can also be configured according to your cluster's status.

After filling in the above parameters, click `Create` to complete the application creation and enter the application configuration page. The following steps will stay the same as you've learned in [Deploy First Application](../quick-start).

Clicking the component name, you can open the component configuration page. For the Helm Chart component, we can set the Values configuration options to change the application deployment parameters. the Values configuration options are generated by `values.yaml`, you can set the custom value for every option.
In the VelaUX, the value key format like `replica.persistence.size=15Gi`. they will be converted to YAML value:
```yaml
values:
replica:
persistence:
size: 15Gi
```
After modifying the deployment parameters, the workflow of the environment must be executed to make the modified parameters take effect in the specified environment. Due to the existence of Revision, the configuration parameters will be saved in each historical version.
## Visualize the resources created by Helm Release
For a helm chart, users often don't know what resources they will create, making it difficult to troubleshoot. In VelaUX, users can visualize the resources created by Helm Release. via the resource graph, users could know the relationships between the resources and the status of all resources. Click the `Detail` action button could view the resource YAML.

## Deploy via CLI
You can also create the application with helm component via CLI:
