# Docker Enterprise Engine Setup

> Learn to install and configure Docker Enterprise Engine on CentOS 7 for secure container workloads.

Learn how to install and configure Docker Enterprise Engine (EE) on CentOS 7 to get your container workloads up and running securely.

## Prerequisites

| Prerequisite           | Description                                                 |
| ---------------------- | ----------------------------------------------------------- |
| Docker Hub ID          | An active Docker Hub account.                               |
| Docker EE Subscription | A paid subscription or a 30-day trial (for evaluation use). |
| Supported OS           | CentOS 7 (x86\_64)                                          |

  If you don’t have a subscription, sign in to Docker Hub and click **Start One-Month Trial** to enable Docker EE repositories for your account.
</Callout>

## 1. Obtain Your Docker EE Repository URL

1. Sign in to Docker Hub.
2. Navigate to **Subscriptions** and start your trial or activate your paid plan.
3. Copy the repository URL provided under **Docker Enterprise Engine**.

You’ll use this URL in the next step to configure your host.

## 2. Configure the Docker EE Repository

Replace `<YOUR-REPO-URL>` with the URL you obtained:

```bash theme={null}
sudo yum install -y yum-utils
sudo yum-config-manager \
  --add-repo \
  <YOUR-REPO-URL>
```

<Callout icon="triangle-alert" color="#FF6B6B">
  Make sure your subscription is active; otherwise the repository will return a 404 error.
</Callout>

## 3. Install Docker Enterprise Engine

Once the repository is added, install Docker EE and its dependencies:

```bash theme={null}
sudo yum install -y docker-ee docker-ee-cli containerd.io
```

Enable and start the Docker service:

```bash theme={null}
sudo systemctl enable docker
sudo systemctl start docker
```

## 4. Verify the Installation

Run the following command to confirm you’re using Docker Engine – Enterprise:

```bash theme={null}
docker version
```

Expected output sample:

```bash theme={null}
Client: Docker Engine - Enterprise
 Version:           19.03.5
 API version:       1.40
 Go version:        go1.12.12
