+title: Try Docker Datacenter
+description: Learn how to  get a trial license and install Docker Datacenter
+keywords: docker, datacenter, install, orchestration
+---
+
+The best way to try Docker Datacenter for yourself is to get the [30-day
+trial available at the Docker Store](https://store.docker.com/bundles/docker-datacenter).
+
+Once you get your trial license, you can install Docker Datacenter in your
+Linux servers.Make sure all the hosts you want to manage in with Docker
+Datacenter have a minimum of:
+
+* Linux kernel version 3.10 or higher
+* CS Docker Engine version 1.12.1 or higher
+* 2.00 GB of RAM
+* 3.00 GB of available disk space
+
+Also make sure the hosts are running one of these operating systems:
+
+* CentOS 7.1 or 7.2
+* Red Hat Enterprise Linux 7.0, 7.1, or 7.2
+* Ubuntu 14.04 LTS
+* SUSE Linux Enterprise 12
+

+
+
+### Step 2: Install CS Docker Engine
+
+Install the commercially supported Docker Engine on all hosts you want to manage
+with Docker Datacenter.
+
+Log in into each node using ssh, and install CS Docker Engine:
+
+```bash
+curl -SLf https://packages.docker.com/1.12/install.sh | sh
+```
+
+[You can also install CS Docker Engine using a package manager](../cs-engine/install.md)
+
+### Step 3: Install Universal Control Plane
+
+Docker Universal Control Plane (UCP) allows managing from a centralized place
+your images, applications, networks, and other computing resources.
+
+Use ssh to log in into the host where you want to install UCP and run:
+
+```none
+docker run --rm -it --name ucp \
+  -v /var/run/docker.sock:/var/run/docker.sock \
+  docker/ucp install \
+  --host-address <node-ip-address> \
+  --interactive
+```
+
+This runs the install command in interactive mode, so that you're prompted
+for any necessary configuration values.
+
+### Step 4: License your installation
+
+Now that UCP is installed, you need to license it. In your browser, navigate
+to the UCP web UI and upload your license.

+
+### Step 5: Join more nodes to UCP
+
+Join more nodes so that you can manage them from UCP.
+Go to the **UCP web UI**, navigate to the **Resources** page, and go to
+the **Nodes** section.
+
+![](ucp/2.0/guides/images/try-ddc-2.png)
+
+Click the **Add Node button** to add a new node.
+
+![](ucp/2.0/guides/images/try-ddc-3.png)
+
+
+Check the 'Add node as a manager' option to join the node as a manager
+to provide replication and make UCP highly available. For an highly available
+installation, make sure you have 3, 5, or 7 manager nodes.
+
+Copy the command to your clipboard, and run in on every node that you want
+to be managed by UCP. After you run the command in the node, the node
+will show up in the UP web UI.
+
+### Step 6: Install Docker Trusted Registry
+
+Docker Trusted Registry (DTR) is a private image registry so that you can
+manage who has access to your Docker images. DTR needs to be installed on
+a node that is being managed by UCP.
+
+Use ssh to log in into the host where you already installed UCP, and run:
+
+```none
+docker run -it --rm \
+  docker/dtr install \
+  --ucp-node <node-hostname> \
+  --ucp-insecure-tls
+```
+
+Where the `--ucp-node` is the hostname of the UCP node where you want to deploy
+DTR. `--ucp-insecure-tls` tells the installer to trust the certificates used
+by UCP.
