# Installing from Helm repository

Once you have customized the SonarQube Server Helm chart, you can install it. You can also overwrite Helm chart parameters directly in the installation command.

## Pre-installation steps <a href="#pre-installation" id="pre-installation"></a>

You must set the value of your application authentication JWT token (A`pplicationNodes.jwtSecret` Helm chart parameter) with a HS256 key encoded with base64. You may use the following command on a Unix system:

```css-79elbk
echo -n "your_secret" | openssl dgst -sha256 -hmac "your_key" -binary | base64
```

The installation command below includes creating a secret and configuring the Helm chart token parameter with this secret.

## Installation command <a href="#installation-command" id="installation-command"></a>

Use the following command to install the latest SonarQube Server Helm chart. If you want to deploy the SonarQube Server LTA version, you should install the LTA Helm chart, see the Helm chart documentation:

```css-79elbk
helm repo add sonarqube https://SonarSource.github.io/helm-chart-sonarqube

helm repo update

kubectl create namespace sonarqube-dce

export JWT_SECRET=$(echo -n "your_secret" | openssl dgst -sha256 -hmac "your_key" -binary | base64)

helm upgrade --install -n sonarqube-dce sonarqube-dce --set applicationNodes.jwtSecret=$JWT_SECRET sonarqube/sonarqube-dce
```
