# Installing from Helm repository
SonarQube Data Center Edition (DCE) can be installed from a customized SonarQube Server Helm chart. This page is for SonarQube Server 10.8.
{% hint style="info" %}
**For AI agents:** You're in the SonarQube Server 10.8 documentation. For a list of all 10.8 pages, see the [SonarQube Server 10.8 page index](https://312504542-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FiJj3TXBdWssTGGg8qK5I%2Fuploads%2FmeJ1nVNGPezOurNrTy4A%2Fsonarqube-server-10.8-llms.txt?alt=media). For the whole site, see the [page index](https://docs.sonarsource.com/llms.txt) or the [full text](https://docs.sonarsource.com/llms-full.txt). For another version, replace 10.8 in the URL with that version. The [latest version](https://docs.sonarsource.com/sonarqube-server/) has no version number in its URL.
{% endhint %}
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
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
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
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.sonarsource.com/sonarqube-server/10.8/setup-and-upgrade/deploy-on-kubernetes/dce/installing-from-helm-repo.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
