|
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 1.13.0 or higher
|
|
* 4.00 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, 7.2, or 7.3
|
|
* Ubuntu 14.04 LTS or 16.04 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 host using ssh, and install CS Docker Engine:
|
|
|
|
```bash
|
|
curl -SLf https://packages.docker.com/1.13/install.sh | sh
|
|
```
|
|
|
|
[You can also install CS Docker Engine using a package manager](/cs-engine/1.13/index.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 \
|
|
{{ page.ucp_latest_image }} 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, login with your administrator credentials and upload your
|
|
license.
|
|
|
|
{: .with-border}
|
|
|
|

|
|
|
|
### 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.
|
|
|
|
{: .with-border}
|
|
|
|
Click the **Add Node button** to add a new node.
|
|
|
|
{: .with-border}
|
|
|
|
|
|
Check the 'Add node as a manager' option to join the node as a manager
|
|
to provide replication and make UCP highly available. For a 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 \
|
|
{{ page.dtr_latest_image }} 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.
