Docker Enterprise Engine Setup

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)

Note

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.

1. Obtain Your Docker EE Repository URL

Sign in to Docker Hub.
Navigate to Subscriptions and start your trial or activate your paid plan.
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:

sudo yum install -y yum-utils
sudo yum-config-manager \
  --add-repo \
  <YOUR-REPO-URL>

Warning

Make sure your subscription is active; otherwise the repository will return a 404 error.

3. Install Docker Enterprise Engine

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

sudo yum install -y docker-ee docker-ee-cli containerd.io

Enable and start the Docker service:

sudo systemctl enable docker
sudo systemctl start docker

4. Verify the Installation

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

docker version
