# BitBucket Data Center Auth

This page is for configuring auth via BitBucket Data Center (on-prem). If you are using BitBucket Cloud please refer to the docs [here](/ci/recipes/enterprise/on-premise/auth-bitbucket).

Before creating your container, your Bitbucket Data Center admin will need to create an "Application Link".

## Connect your Nx Cloud installation to your new app

It's now time to enable auth on NxCloud. Refer to the [auth guide](https://github.com/nrwl/nx-cloud-helm/blob/main/AUTH-GUIDE.md) here for instructions on configuring your Helm values file.
