-
-Once you deploy Docker Trusted Registry (DTR), you can use it to store your
-Docker images and deploy services to UCP using these images.
-[Learn how to deploy DTR](/ee/dtr/admin/install/index.md).
-
-Docker UCP integrates out of the box with Docker Trusted Registry (DTR).
-This means that you can deploy services from the UCP web UI, using Docker
-images that are stored in DTR. You can also use a
-[UCP client bundle](../../user-access/cli.md) to do the same from the
-CLI.
-
-If you've configured DTR to use TLS certificates issued by a globally-trusted
-certificate authority, you can skip this, since all clients will automatically
-trust the TLS certificates used by DTR.
-
-If you're using the DTR default configurations or configured DTR to use
-self-signed certificates, you need to configure all hosts that want to push
-or pull Docker images from DTR. This includes:
-
-* All UCP nodes
-* Your local computer or any other that wants to push or pull Docker images
-  from DTR
-
-If your host isn't configured to trust the DTR TLS certificates, you'll get an
-error like:
-
-```none
-docker login dtr.example.org
-
-x509: certificate signed by unknown authority
-```
-
-## 1. Configure your local computer
-
-If you want to use your local computer to interact with DTR, you need to
-configure it to trust the DTR TLS certificates. This depends on the operating
-system:
-
-* For macOS:
-
-  In your browser navigate to `https://<dtr-url>/ca` to download the TLS
-  certificate used by DTR. Then
-  [add this certificate to the macOS trust store](https://support.apple.com/kb/PH18677?locale=en_US).
-
-* For Windows:
-
-  In your browser navigate to `https://<dtr-url>/ca` to download the TLS
-  certificate used by DTR. Then
-  [add this certificate to the Windows trust store](https://technet.microsoft.com/en-us/library/cc754841(v=ws.11).aspx).
-
-* For Ubuntu:
-
-  ```bash
-  # Download the DTR CA certificate
-  sudo curl -k https://<dtr-url>/ca -o /usr/local/share/ca-certificates/<dtr-domain-name>.crt
-
-  # Refresh the list of certificates to trust
-  sudo update-ca-certificates
-
-  # Restart the Docker daemon
-  sudo service docker restart
-  ```
-
-* For CentOS or RHEL:
-
-  ```bash
-  # Download the DTR CA certificate
-  sudo curl -k https://<dtr-url>/ca -o /etc/pki/ca-trust/source/anchors/<dtr-domain-name>.crt
-
-  # Refresh the list of certificates to trust
-  sudo update-ca-trust
-
-  # Restart the Docker daemon
-  sudo /bin/systemctl restart docker.service
-  ```
-
-## 2. Test your local setup
-
-To confirm that your computer is configured correctly, try to pull and push
-images from your local Docker installation to DTR.
-
-1.  Create a test repository on DTR.
-
-    Navigate to the **DTR web UI**, and create a new **hello-world** repository
-    so that you can push and pull images. Set it as **private**, and save
-    the changes.
-
-    ![](/ee/ucpimages/dtr-integration-1.png)
-
-2.  Pull the `hello-world` image from Docker Store, re-tag it, and push it to the
-DTR repository you created.
-
-    ```none
-    # Pull hello-world from Docker Store
-    docker image pull hello-world:latest
-
-    # Re-tag it
-    docker tag hello-world:latest <dtr-domain>/<user>/hello-world:latest
-
-    # Log into DTR
-    docker login <dtr-domain>
-
-    # Push your image to DTR
-    docker image push <dtr-domain>/<user>/hello-world:latest
-    ```
-
-3.  Validate that your image is now stored in DTR.
-
-    When successfully pushing the image you should see a result like:
-
-    ```none
-    The push refers to a repository [dtr/username/hello-world]
-    5f70bf18a086: Pushed
-    33e7801ac047: Pushed
-    1: digest: sha256:7d9e482c0cc9e68c7f07bf76e0aafcb1869d32446547909200db990e7bc5461a size: 1930
-    ```
-
-    You can also check that the tag exists on the DTR web UI.

-
-## 3. Configure UCP Docker Engines
-
-You also need to configure the Docker Engine on every UCP node to trust the
-DTR TLS certificates. This allows you to deploy services to UCP using images
-that are stored in DTR.
-
-For each UCP node:
-
-1.  Log into the node as an administrator, using ssh.
-2.  Configure the system to trust the DTR TLS certificates, following the same
-steps as you used to configure your local computer.
