# Installing from Google Cloud Platform

Data Center Edition can be deployed on Kubernetes through the Google Marketplace:

* Either with basic features only, by using its *Click to Deploy* feature.
* Or with advanced features by using its *Deploy via command line* feature.

## Basic installation

With the basic installation, you cannot benefit from various features such as autoscaling or deploying with Istio.

### Prerequisites

Make sure that kubectl is configured in your environment and that your cluster has Google’s Application CustomResourceDefinition installed. That definition can be obtained from [this file](https://raw.githubusercontent.com/GoogleCloudPlatform/marketplace-k8s-app-tools/master/crd/app-crd.yaml).

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

* Set the value of your Application authentication JWT Token. See [jwt-token](https://docs.sonarsource.com/sonarqube-server/server-installation/pre-installation/jwt-token "mention").
* If necessary, create the target namespace you want to install Data Center Edition into.

### Installing using Click to Deploy <a href="#click-to-deploy" id="click-to-deploy"></a>

1. Go to the [Data Center Edition page](https://console.cloud.google.com/marketplace/product/sonarsource-public/sonarqube-data-center-edition) on the Google Cloud Platform.
2. Click **Get started** and follow the instructions.
3. In the **Deploy** page, fill in the fields in the **Click to Deploy on GKE** tab: see **Installation parameters** below.
4. At the bottom of the tab, click **Deploy**.

### Installing manually <a href="#installing-manually" id="installing-manually"></a>

For manual installation or development purposes, SonarQube Server can be configured using the [mpdev CLI tool](https://github.com/GoogleCloudPlatform/marketplace-k8s-app-tools) provided by Google. See Installation parameters below for the supported parameters with key.

### Deleting the installation <a href="#deleting-installation" id="deleting-installation"></a>

To delete the installation of SonarQube Server from your cluster:

1. Delete the created Application resource.
2. Delete the PersistentVolumeClaims related to the search nodes and database (if applicable).

## Advanced installation

Use the advanced installation if you want to benefit from various features such as autoscaling or deploying with Istio.

Proceed as follows:

1. Customize the Helm chart. See Customizing the Helm chart.
2. Go to the [Data Center Edition page](https://console.cloud.google.com/marketplace/product/sonarsource-public/sonarqube-data-center-edition) on the Google Cloud Platform.
3. In the **Deploy** page of your Google Cloud Platform, select the **Deploy via command line** tab.
4. Follow the instructions:
   1. Clone the[ repo](https://github.com/SonarSource/helm-chart-sonarqube).
   2. Use the command described in [installing-from-helm-repo](https://docs.sonarsource.com/sonarqube-server/server-installation/data-center-edition/on-kubernetes-or-openshift/installing-from-helm-repo "mention").
