# Install the VAST COSI Driver Helm Chart

Installing a Helm chart results in deployment of a VAST driver's *release* in your Kubernetes environment. A release is identified with its release name, which you supply during the install.

To install the VAST COSI Driver chart:

1. Refresh Helm repository information:

```plaintext
helm repo update
```
2. Run the following command to initiate the install:

```plaintext
helm install <release name> <repo>/<chart> -f <filename>.yaml -n <namespace> [--set-file sslCert=VastCerts/RootCA.crt]
```

Where:

  - `&lt;release name&gt;` identifies the release being deployed.
  - `&lt;repo&gt;` is the name of the [VAST COSI Driver Helm repository](/develop/docs/add-the-helm-repository-for-vast-cosi-driver-2-5).
  - `&lt;chart&gt;` is the name of the Helm chart to be installed (`vastcosi`).
  - `&lt;filename&gt;.yaml` is the [Helm chart configuration file](/develop/docs/create-a-helm-chart-configuration-file-for-vast-cosi-driver-2-5) for VAST COSI Driver.
  - `&lt;namespace&gt;` (optional) determines the Kubernetes namespace to which the release is deployed. If this parameter is not specified, the `default` namespace is used. Otherwise, [create](/develop/docs/en/create-a-kubernetes-namespace-for-vast-cosi-driver-1) a custom namespace prior to installing the Helm chart.
  - `--set-file sslCert=VastCerts/RootCA.crt` (optional) specifies the path to a self-signed SSL certificate to [secure](/develop/docs/en/configuring-ssl-encryption-for-vast-cosi-driver-1) the connection to the VAST cluster.

For example:

```plaintext
helm install cosi-driver vastcosi/vastcosi -f values.yaml
```

The output is similar to the following:

```plaintext
NAME: cosi-driver
LAST DEPLOYED: Thu Dec  5 05:24:36 2024
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
Thank you for installing vastcosi.

Your release is named cosi-driver.
The release is installed in namespace default

To learn more about the release, try:

  $ helm status -n default cosi-driver
  $ helm get all -n default cosi-driver

<...>
```
3. Verify that the Helm chart has been installed as follows:

  - Check the release status with the following command:

```plaintext
helm status -n <namespace> <release name>
```

For example:

```plaintext
helm status -n default cosi-driver
```
  - Ensure that the release appears in the list of releases:

```plaintext
helm list -n <namespace>
```

For example:

```plaintext
helm list -n default
```

The output is similar to the following:

```plaintext
NAME            NAMESPACE       REVISION        UPDATED                                 STATUS          CHART           APP VERSION
cosi-driver     default         1               2024-12-01 04:25:33.783236165 +0000 UTC deployed        vastcosi-0.1.0  2.5.0    
```
