This section explains how to install Data Center Edition on Kubernetes or OpenShift (see also the [SonarQube Server Helm chart documentation](https://artifacthub.io/packages/helm/sonarqube/sonarqube-dce)).

To deploy Data Center Edition on Kubernetes or OpenShift:

1. Read [before-you-start](https://docs.sonarsource.com/sonarqube-server/server-installation/data-center-edition/on-kubernetes-or-openshift/before-you-start "mention").
2. Customize the Helm chart and install it in Kubernetes. See:

   1. [Customizing the Helm chart](https://docs.sonarsource.com/sonarqube-server/server-installation/data-center-edition/on-kubernetes-or-openshift/customizing-helm-chart)
   2. [installing-from-helm-repo](https://docs.sonarsource.com/sonarqube-server/server-installation/data-center-edition/on-kubernetes-or-openshift/installing-from-helm-repo "mention")

   Alternatively, if you want to deploy from the Google Cloud Platform, see [installing-from-gcp](https://docs.sonarsource.com/sonarqube-server/server-installation/data-center-edition/on-kubernetes-or-openshift/installing-from-gcp "mention").
3. Once your SonarQube Server is installed and running, you can access SonarQube Server UI in your web browser (the default system administrator credentials are **admin**/**admin**) and you’re ready to begin [overview](https://docs.sonarsource.com/sonarqube-server/analyzing-source-code/overview "mention").
4. If you have customized your Helm chart, you can now encrypt sensitive data in your `values.yaml` file. See [encrypting-helm-chart-sensitive-data](https://docs.sonarsource.com/sonarqube-server/server-installation/on-kubernetes-or-openshift/encrypting-helm-chart-sensitive-data "mention").
